- If you're looking for a top quality battery pack for your Radiomaster TX16S with decent life (run time), the Gens Ace 4000 2S TX pack is a great fit and good value for around $25 USD.
Let's look at the size of this TX16S battery option, install it and calibrate the battery voltage on the TX16S. Lastly, we'll calculate the safe running time for this TX16S battery pack.
To calibrate the TX16S battery voltage and calculate the run time, you'll need a digital multi-meter (DMM). However, from the video, I'll show the operating current of a typical TX16S with full screen brightness and volume level, so you could use that value for any other TX16S LiPo battery pack you might want to get a battery life estimate on.
You could also perform a rough voltage calibration by subtracting about 0.03V from the battery pack's open circuit voltage if you can't test your battery while it's running in your radio.

Good job John, I just ordered the battery pack for my tx and I ordered the Eachine 180 heli about a week ago. Looking forward to your review of this heli.
Nice 👍
Hi John, Really helpfull vid,I bought the Jumper T16 when it first came out.Had a lot of the early issues with mine. really thinking about getting this radio to replace the jumper.
Also looking forward to the e180 vid, hoping this will be cheaper option over the OMP,thas out my price range.
Just now considering getting back into RC from a time when, 1/2 the RC plane club scoffed at this new wiz bang computer radio idea. "that will crash your model", "skilled pilots don't need that", or "that's cheating", etc...
Similar thing happened when brushless motors came along.
Wish I could see today, what's coming in another 25 years?
Looking forward to your thoughts on the E-180.
Me too - LOL
@@Rchelicopterfun Lolz, got out this past Thursday for the first time this year. Felt great to get in the air again :)
Hi John, what do you do storage (between flying sessions) wise for the lipo inside the TX? I have a 5000mah lipo in my TX16 and I'm not entirely comfortable leaving the lipo inside the TX....
I cover my LiPo storage methods on my RC LiPo Batter Page: www.rchelicopterfun.com/lipo-batteries.html
As stated on that page, I never store any Lipo pack (including a TX pack) much over 50% for more than a couple/three days at most.
Great Video John, While you are talking batteries, can you tell me what power units you use for your Ichargers please, some are stupid money when you start talking power for a icharger 4010
I cover the basics of what I use on my power supply page on my site: www.rchelicopterfun.com/rc-power-supply.html
Can't go wrong with Meanwell but for my iChargers including the 4010DUO I pretty much use modded server supplies exclusively which I cover in detail on this page: www.rchelicopterfun.com/dps-600pb-build.html
I use 4 of them hooked in series to power my 4010Duo. You should be able to find 4 HP DPS-600's for under $100 USD combined. The value doesn't get any better than that - nor does the quality :)
@@Rchelicopterfun thank you john. Help really appreciated
Hi John.
Thanks for the comprehensive video.
The whole business is mind boggling when we mess with lipos.
I have a printed out book form copy of the Radiomaster T16s manual and it says all about the importance if charging but not exactly what source we plug it into to charge it.
I am innocently using my pc but having thought about it I seem to remember that the usb socket on a pc is only 5v.
I am at a complete loss.
No one says!!!
I am using the lipos ( 1850s)
That came with the tx.
The tx goes green when charging but it would surely need roughly 8V to charge 7.4V?
Internal charge circuitry uses a DC to DC buck converter. Ie. lower DC voltage stepped up to higher voltage.
@@Rchelicopterfun
Aha!!! That explains things.
I have done your switch mod ready for heli setup.
For the speaker mod, on opening the case up I already had a speaker in the back. I drilled a series of holes in the back casing from the inside and turned the speaker around .
Super loud now.
Thanks John.
Thanks for this useful tutorial. Just got the Gens Ace 4000mAh 2S pack and got some error when trying to charge w/ my Gens Ace iMars ii charger. it says "too low voltage, scrap the battery". The batttery new/never used and each cell 3.8V. Don't understand. Do you have to use the EHR cable in addition of the balance plug?
If you are not charging the pack through the TX16's internal charging circuit via the USB-C, then yes, as with the vast majority of RC chargers when charging a multi celled LiPo pack, you charge through the main power plug and balance through the balance plug. Without the main plug plugged into your charger, it's not seeing any voltage and therefor thinks the pack is at zero volts and completely destroyed - www.rchelicopterfun.com/lipo-battery-balancing.html
Hi!
Great tutorial. Was trying to learn more about charging the battery via usb-c using this radio.
Is there a known issue with this radio when charging via usb-c?
I am using an identical battery as shown here, new arrived today. And trying to charge it inside the radiomaster tx16s Max. After a couple of hours it didn't send any charge to the battery - I checked with multimeter after removing it from the radio.
Thanks
No issues I'm aware of. I have three TX16's and they all charge perfectly from the USB C just as shown in this video. I know lots of other TX16's users as well, none have charging issues. Is the power light turning green when you plug your USB in? Green light indicates it's charging. I'll also presume you are plugging into the correct USB port for charging; the one on the bottom of the radio, not the one on the top.
@@Rchelicopterfun Thanks. I was plugging to the bottom USB port and was using an iPhone wall charger and USB-C cable - no charging nor green light. After reading your words, decided to try a different charger and tried my MacBook Pro wall charger since it has a USB-C plug - it worked! Green light indicating it was charging and after a couple of hours green light turned off.
Thanks again.
@Vitor Morais - glad you got it sorted.
Hi there, Im a Pilipino Fan of you
Would the current draw not be higher as usually the RC has the radio sending/receiving data (including the radio in the external module which can sometimes be configured for high power to reach further)? Or would this be neglectable?
Current (transmit output) is a constant for a given protocol, it doesn't get higher or lower with range. The single biggest power consumer is the screen.
Just love hearing Canadians when they use metric system ;)
Welcome US... you are most welcome to join :)
Jokes aside, thank you most informative :)
🙂
I went with this same battery for my Tx16s and I was wondering if you only charge these packs via transmitter or if you use the icharger at times. I have a tenergy charger for other lipos but doesn't seem to have capability unless I'm missing something? Any info would be greatly appreciated
@SovOutlaw - You can charge a LiPo TX pack internally or externally - your call. Which method you choose will be based on the pros & cons of each charging method and which ticks off more pro boxes than con boxes which include, but are not limited to...
Pros of charging within the radio: Easier, better for the connectors (less manipulation which will eventually cause them to fail), frees up your LiPo charger for flight packs.
Cons: Slower (lower current output using internal radio charge circuitry), inability to easily storage charge the pack to 50% capacity (likely the biggest con), and inability to monitor battery condition (capacity during charge cycle, cell balance, internal resistance etc.). I personally chose to charge within the radio 90% of the time because the balance circuitry is good as we saw & I overcome the storage charge issue by timing my charge cycle to give an approx. 50% storage state. Of course I still pull the packs out a couple times a year to charge them on one of my proper computerized chargers to monitor the pack condition/health.
@@Rchelicopterfun yeah I think the only option currently (without buying a new charger) is to try internal charging with a 2A outlet plug I can use on usb side. The tenergy charger I have is a 2 system setup where it had balancer and output area and the other cable labeled “do not remove” isn’t a balance port so I can’t even set that up to current other rc charging stuff. Poorly worded so my apologies
Where did you get your 242 loctite from and how much did it cost?
I saw a 250ml one for like £240 from somewhere and a 50ml one for £12.50 from amazon. I'm not sure if the amazon is legit so could you please give me the link for where you bought yours?
Get my Loctite from our local machine shop. They have no site - so no link. $45 CND for 50ml bottle.
i have a lion 7.4V 5.0AH on my radiomaster, what is range of voltage it should be set up in the edge tx
I acquired 2 higher end RC vehicles, one Baja bug and a Bronco, anyplace you could point me to for how to set these units up as they haven't run in about 3 years. Thank you.
No idea, I'm an RC helicopter guy only.
Hi John,
I just got this radio(i am a complete beginner btw) and have installed two 18650 batteries which are 3.7v each with a capacity of 3000mah. the first thing i did was that i put it on charge. What i noticed during charging is that, when on charge there is a green light constantly ON which goes off once its done charging (or so i thought), so when the light went off i took it off the charge and noticed that the radio wasn't fully charged(the bars werent full at the top). As I dont have a multimeter i just set the battery calibration to 7.4v as both cells are 3.7v each and the battery meter range to 6.4v-8.4v. Is something wrong with my radio or the calibration values I set? Any help is appreciated, i just hope i havent gotten a defective radio.
Nothing wrong with the radio, it's your calibration process.
First you MUST use a DMM to do this correctly. Without a DMM your reading is only as good as your guess; and your fully charged voltage guess is way off. 3.7V is not what a fully charged lithium cell will be producing. 3.7V is the nominal voltage of the cell. Fully charged, the cells will be upwards of 4.18 to 4.19 volts (unloaded). You can't use that voltage however for calibration because the voltage will sag under load. The voltage will also sag by different amounts depending on how much load is on the battery (screen brightness level for example) and how healthy/good the battery cells are.
In short, using a DMM is the only way to calibrate the actual voltage - guessing is just that - guessing.
You can also vary the voltage meter readout on OpenTX radios, but that again requires some form of voltage measurement equipment.
@@Rchelicopterfun Thanks for the reply. So you're saying that the battery charge only to the amount you set it to on the battery calibration? Because what I did was, I plugged the tx in with a 18W plug that charges upto 2.4A. And when the green light went off, I unplugged it and turned it on. After turning it on I could see on the main page that the battery voltage was at 7.5 volts with 2 bars off the battery symbol. This was before I did any messing with the system settings and calibration. And then after commenting on here about the issue, I tried to charge it with a 5v 1A plug, and it charged fully upto 8.2v which makes sense now as you said the lithium cells charge upwards upto 4.18v. Why did this happen? Was it the plug I used previously? if so, why did it stop at 7.5v?was it the plus I used?
The voltage calibration process as shown in this video has nothing to do with charge termination voltage. That is set in the built in charger circuitry and we have no control over it. Calibration simply matches the voltage readout to what the actual under load battery voltage is.
Sorry, I don't understand what you are saying about these different plugs? Are you talking about the USB C cable or the USB power source? No idea why different USB power sources or USB C cables would produce different states of charge? Faulty USB perhaps or a USB power source with some sort of automatic current output which is messing with the internal charger in the radio? Just a guess without being able to test it all. Suggest contacting tech support.
How does the charging work? and do you know it is charged?
Charging & balancing is done using the radio's internal 2S charging circuitry. When the green indicator charging LED indicator (power indicator) turns off - charging and balancing is complete.
I noticed that you charged the lipo, the battery meter is looking almost dead on the transmitter at the 14:00 in the video
Good eye. Answer is because the pack was not fully charged during that part of the video. The open circuit voltage when tested earlier in the video was 7.6V (3.8v per cell). That would be around a 40-50% charged pack. Pretty much what the battery meter is showing. Charging the pack to see how well it balanced up using the radio's internal charging & balancing circuit was left to after the video because I didn't want to stop shooting in the middle of it all to wait for the pack to charge up.
I just got the color version. using a 2s lipo but when I trying charging it grenn light dont come on. am I missing a setting? is internal charge even working? just got radio last night.
No setting in the radio - it should start a charge cycle automatically as soon as you plug the USB C in. A few items come to mind to check or try. 1. Try a different USB cord in the off chance the USB cord is defective. 2. Confirm you are using the correct USB C port on the radio (the bottom one for charging). 3. Try a different USB power source. 4. If the LiPo pack or 18650 cells are unhealthy (high delta voltage difference between cells) or under a certain voltage (ie. over discharged or faulty cells), the protection circuitry in the charge circuit might prevent the charge cycle. No idea if the charger in the TX16S's has LV or imbalance charge protection as I've never tested what happens if an under voltage or large imbalanced pack is used? 5. The pack or cells you're using are already fully charged (about 4.19 to 4.20V per cell) so a charge cycle simply won't start.
@@Rchelicopterfun yes my mistake... I plugged in the power instead of the balance plug from the battery into the radio once I did that correctly it worked fine.. I had to think about it for a few minutes and then I realized it all good now though.
did they send you the eachine e180 rtf?
Stay tuned 🙂
You didn't connect the radio to a model, I'm assuming that will draw another 75-300ma as well for ELRS, etc?
Radio was transmitting rf regardless. No change if rx is receiving or not.
❤👍👍👏
Hi, I'm using the stock battery tray and Samsung 18650 batteries. I've tried calibrating the voltage several times now while connected (MM between the end posts on the battery for total voltage. The voltage sag just from screen brightness changes gives me different readings. (Forgot which way now). Meter is good. It picks up on the sag/voltage drop, but if i have it match on low brightness, my meter and radio aren't match on high brightness.
That said, I've never had the light turn off for me. I let it charge overnight this weekend, and all morning the next day, light never shut off. When I checked the voltage in the radio I got 8.29 with screen dimmed. My bay charger showed 4.15 per cell. My mm agreed with that.
What gives?
I'm about to pull the batteries off my bay charger when full. Put in holder, use my lipo checker to get voltage per cell, add them up, and power on a quickly set the combined value in the radio to see if that gets it to charge fully.... Please stop me if this might burn it down next time I charge through the radio port.
Pick the display brightness you usually run at or a mid range of where you run at an set voltage calibration at that level/current draw. It's likely due to high internal resistance in the 18650 cells you are using but that is just a guess without properly testing it and knowing exact values (voltage and current draw and testing the internal resistance of each 18650 cell).
The method you described won't give a true value because checking the open circuit voltage (unloaded) will give a significantly higher voltage value than when loaded, especially if your cells have fairly high internal resistance. Exactly why I said in the video it's important to have an external power plug on the battery pack to check the under load operating voltage - that is the only way to get accurate voltage values and then set the calibration voltage. To do that with the stock battery tray, you could solder in a pair of "test" wires as one possible method with a JST plug/similar on the end. That or don't worry about it. After all as we saw, out of the box calibration was pretty darn close - at least on this particular TX16S.
@@Rchelicopterfun Thanks John. Maybe it is IR discrepancy but they way I see it, I charge it with the radio off. And it if the green light indicates it's charging, it never stops charging. I opted to charge them full on my trustfire bay charger, plugged it in, and it yeilded 8.56v on the transmitter while my MM showed 8.46. So I went ahead and brought it back down. I don't typically look at the display while flying, and it goes bright based on buttons only. I calibrated it while dimmed. I'll probably charge it again this weekend depending how much I can get out (or how much I play with a different technique of using FM GV). I'd really just like to get it so it reaches a "done" state and quits charging...
I use 21700 round cells... 2 in parallel so around 10 Ah.. Why so big? My fpv googles also use 2s 8.4V...and with the bigger cells in the trx i can power the googles and save some weight on my head
Should i leave the battery inside the transmitter or remove it after each use
I leave mine in - at a storage state of course like you would with any LiPo battery.
@@Rchelicopterfun ok, so around 7v should be safe to hang out at if i use it daily? And thanks, i really appreciate you taking the time to answer.
7V open circuit voltage is way too low. That's only 3.5V per cell - basically over discharged. A lipo at 50% safe storage capacity is around 3.85V per cell. See my LiPo page on my website if you are new to LiPo's and need to understand their nominal voltage range and how to properly store them, care for them, etc. www.rchelicopterfun.com/lipo-batteries.html
Where did you get that funny sound pack?
OpenTX University. "Amber"
And xou can make your own with tts automate...
hey quick question
My Radiomaster isnt auto charging when its plugged to pc, do someone know why or what i need to activiate to charge it?
Are you plugged into the USB slot on the bottom of the radio? That top USB is for data and bottom for charge.
i noticed on the display there was a picture of model how do you do that?
Upload the image file to the image folder on the SD card and then select the image file in the model setup menu.
@@Rchelicopterfun I tried that radio recognized the fire I got it in the setup but image is still not showing. The aircraft is not binded yet could that be it?
I plugged my LiPo in reversed for a sec and now my tx16 is glitching is it done for
Best to ask a Radiomaster retailer, but my guess is yes, the power board/circuit has likely been fried.
