I had one of these batteries - it worked well for a couple of months, then I think that a cell or the bms went bad, either way the battery was not functional. Factory made a swift refund. Not sure if mine was a fluke or what, but that was my experience.

How do you know when the battery is fully charged with that controller?

Thanks for sharing your QRP experience. Not using the output without a cutoff was a bit ah-ha for me with another batter pack that is similar for jump starts.

Great video, thanks!! Robert K5TPC

At least it's trying to send a positive message at the time..

So even though the cells in the end are all going in the same place, does it actually matter in the order that you set them in when you create the headway bank?

I DID MINE IN A FEW SECONDS WITH JUST A PINPOINT TOOL. SCRAPED THE BRIDGE OUT. WORKED FINE.

Niceee

I just put mine inside a container with aluminum foil around the container and grounded the foil works a bit

Is it meant to be backwards english "stop war"

I'm a bit shocked to see the inside of it. It looks like they were in a hurry, not professionally done in my opoininnio. I thought LDG products were better than that. I at least hope it performed okay in the field.

At :30 you say "to control the temperature to what ever I set it". Does that mean it can simultaneously heat and cool as necessary? In my app I want my photochemistry to be at a fixed temp, despite the ambient temp. I've seen various units that have a selector for hot/cold.. are there others that can detect and ..as in your case ... make the temp as designated? Does the module expand on this... ie heat or cool as needed to reach the temp.. or is this solely related to the function of the cooler and your thermostat limited to a certain range (voltages?) In your test/demo you have the unit powered (male cig lighter inserted to 12V source) The female cig lighter goes to cooler' input (Male12V cig? ) Not afraid of new challenges.. but fundamental education lacking

This looks interesting.. Does it throttle the input to lower or increase the temp, or is this simply a thermometer or thermostat? ie Can you set a temp and plug in series with the the power . MY idea is to use a thermoelectric cooler to keep the photo chemicals at a constant temperature.. would this be something for/like that?

Is this a mini pole or standard 10m pole?

Haha.. The title should say "I converted my Spiderbeam into a DX Commander"! LOL :)

godt job

Does this fit a DX Commander Classic pole?

Thanks good to know

Thanks, I have a high speed USB camera which won't connect when my MPPT controller is connected and generating...:( It took me close to a year to think of this as the problem.

I love my 38120 Headway cells , I made a home made 4S-2P power station with them . But one of the coolest things about the 38120s is that a 12V battery can start a car , I haven't done it yet with my battery but I will eventually . Can the Bioenno battery start a car ? Happy building :)

They can be charge with lead charger even mfg tell you can.. only issue it will only charge to 13.3

Looks messy inside. There's better looking ones online.

When I decided to make my e-bike my primary vehicle I discovered battery hookup. Their pricing seemed too good to be true. I purchased 15 36v 4.4ah (samsung cells) packs that were for hoverboards. I absolutely love these guys! They are hands down my first go to when it comes to lithium cells. They were honest and timely. I'm telling you it was the best deal I've ever gotten. They are the best in used cells and packs. And they are as honest as anyone in the battery business! If your on the fence I hope this helps u make the right choices. I've been had by throttle manufactures and bldc hub motor manufactures. But never in batteries because these guys are the best.

mine comes with a low voltage shutoff in the box going to the crocodile clamps which ive tested and it stops pretty reasonable 11V which with the 6ah im prettymuch never gonna reach since ill use a max if 3AH

I have three of these kits including a few spare batteries.. I use MTO Battery for rebuilding my packs with new cells.

Where did you get the larger vfo knob on your G90?

Thinking of doing it to my FT5DR but i saw pepole saying that they lost the functionality of programming via the USB cable or SD card. is it true?

Cool! But isn’t there an offset for FRS and stuff?

Do you think I could use the balcony rail as ground with this unun? thanks

Sounds like a Cessna a bit, surprisingly!! Thought it will sound like C-130H Classic Herc, since C-27J Spartan sounds like C-130J Super Herc!!

I know I'm late to the party but does this mod expand JUST MARS/CAPthose frequencies? curious about the CB band. 26.9650-27.4050

What are the transmits?

Mine i bought from japan still cant get extended frequency and i open the rubber there is no om resistance

4 Amp draw , that's nerve racking , I have seen the Makita , it uses 2 , 18 v. batteries , it's been out for a while but no one sells it in the U.S.

How fuel efficient are these motors ? How much fuel do you think it would use on that 10 amp load for say 1hr ?

I wish they'd chosen another method of selecting freqs. The way this is setup, specifically the last khz switch offering only 00, 25, 50, 75, means there are only like 5 or 6 6m channels to operate on. I wonder if there's a way to mod one of these to allow continuous control over the last two khz steps, so you could select, say, 51.560 or 52.570?

Man, this was good. I appreciate you putting a review on here about this device. I was looking for something similar and was glad I found this online. Thank you sir!

It's less illegal as more of a gray area.

I do the opposite. Drain the batteries into a known good pack that needs charging anyways. Once they’re all all discharged, I charge them up separately or in groups of 4 (if I’m working with more than 48 or so cells) to measure the capacity that I have and configure accordingly

Just a word of caution... if you wire them all in parallel like you do for charging? You can have a really bad time... These cells can deliver **EIGHT HUNDRED AMPS** when shorted... half that gives you 400A of charging current for any battery that is lower voltage... and the cells are only rated for 200A continuous current draw. This means you damage both the higher voltage cells by drawing 400-800A, and that you damage the lower voltage cells by charging 400-800A when they're rated for 80A charge continuous.

How efficient is it?

Thanks you. I had just ordered it and for the price was worried it would be RF loud. Good to know in theory it will be ok.

Battery hookup says the Ah rating is discharging 1.6a to 2.5volts. I found this out on my Second day of testing. I had a bunch to retest because I was going down to 2.0v

Something "you" designed, please get over yourself! DX Commander

To speed up my testing process. I set the discharge current to 20A. My result was roughly 5.18ah and lasted for 20 minutes till it reached 2v and the alarm 🚨 went off. A few minutes later nominal voltage rises to 3.08v I’m not sure how accurate my test is, but now I’ll try to discharge it at 2a

thanks, nice job 73 from kb2uew

how long did it take you to complete testing for all those batteries. Is there a faster way or a better load tester? Reason why I’m ask is because I bought over a hundred used cells from (BH ) and I would like to know what I have.

I use a home-brew version to activate parks. I use 29’ or 55’ of wire, though 29’ never failed me - I’m not sure if it makes a difference, except maybe on 40. I use a 31’ Jackite pole, making it a pure vertical. I’ve worked stations 9000 miles away with 10W CW, so I guess it’s a very effective antenna. My counterpoise is 16’, and I usually use a home brew 1:1 current balun. My rig is a KX2, and the tuner never fails to give me a match down to 60M. You will not be disappointed.

Good informative video. I purchased one off of Amazon for $81 and a 2 amp LiFePO4 charger to go with it. My battery came about 90% charged? I put the charger on it and it showed fully charged in less than one hour. I am getting another one shortly. They are great batteries for the price. You can use a lead acid battery charger on the battery. BUT.....it won't fully charge the battery since the SLA charger cuts off at a lower voltage. It won't harm the battery, it just won't fully charge. This brand battery is a big savings over the Bioenno battery. Barry, KU3X

Thanks for the nice video. Any special reason why you only did the test with only a 4 Amp load current? I would be interested to see how long it can run 20 Amps (max. continuous rating) and 40 Amps (max peak rating) as shown on your battery's label. Theoretically it should run for 1-hr on 20 Amps and 0.5-hr on 40 Amps, but would like to see their actual performance on these max. ratings...
