- In this video we share some clips of the paint job, explain the Flex-Mount Bumper a bit more and do a functional test of the Lithium Iron Phosphate batteries running an induction cooktop
I know this is super old. It was quite informative and to the point, but there are some things to consider.
Lead Acid batteries are not inferior, but rather comparable to lithium cost wise per kWh cycled. If you get the reputable brands they easily have many thousands of cycles. This depends heavily on DoD though.
So, I 100% agree with all you say besides the cycle life and therefore the life cost.
For your scenario with the RV, lithium is a no brainer considering the weight alone. For home usage with heavy cycling I think you could go either way for a bigger bank. For things like starter batteries that are almost always full and UPSes that may see 10 cycles throughout their lifespan I would first consider lead acid because of the cost and safety.
The internal resistance is interesting and something that might make come over to the lithium side sooner.
Thank you for your videos!
OK, just starting to work my way through your videos. Well actually more play than work, but anyway, must find the one that makes sense of that bumper thing, and for now... wow that cooktop sucks some power. I love it, love all of it, you are one crazy dude
Wear a respirator when spraying paint! Your lungs must've felt great after painting. Your build is
fantastic! Thank you for taking the time to share.
That's not me...! We hired an ex-autobody paint guy, he brought his own gear and when I asked about a mask he said he was filtering his air through the cigarette. That's what you get for a $150.00 paintjob I guess. 🤷♂️
Bugs love fresh paint.
Lots of questions..
1. What size (cm2) are those brake chambers and what pressure to hold down.
2. Does the ElectroDacus have MQTT output.
3. Not a question, but the cooktop is around 50% overall efficiency - which is good
1. There are many sizes available... Google it.
2. Nope
3. Thanks!
Would you mind listing the components for your system? Looking for recommendations for the whole battery monitoring, charge controller, etc...
My plan is to mimic your larger bank, since you have it all working about perfectly! Thanks, and awesome videos!
Our SBMS100 does it all...
What kind of BMS did you get, and where did you get it?
Where did you order your battery components pieces?
It's the SBMS100
Isn’t it a bit small ? SBMS100 is a 100A and your inverter is 1800 Watts ?? My inverter is 2000 Watts, I guess this BMS is too small, is there aborder model bigger ?
No, the 100A rating refers to the charge current from the solar, the inverter has its own dedicated shunt and can pull as much as needed.
Hello Jason - Very specific question about your Xantrex/SBMS combo. Just received the 24V Prosine version of yours, and an SBMS0. Did you just wire SBMS's XTIO3 in series at the Xantrex On/Off behind its display? Dacian informed me the Prosine allows remote on/off w SBMS but that's the only way I can see that this is possible. As you're the only one I've found w this combo, appreciate your advice on this. Happy Trails.
Yes, I just paralleled a small relay behind the switch. This is controlled by a Raspberry Pi which is monitoring the SoC and if safe, it turns it on. This allows for some fancy logic like turning it off if the load is below a setpoint. You could also just the XTIO3 as you say, just wire it through a relay with an opto, something bloke this: www.amazon.ca/SunFounder-Channel-Shield-Arduino-Raspberry/dp/B00E0NTPP4
@@Everlanders Thanks. I don't need anything fancy and still want to be able to turn it on/off via the switch (only occasionally using it) so I'll just interrupt one of the switch wires on the Xantrex and send it through XTIO3 (i.e. series connected). Sounds like you're saying that will work. Thanks.
So you are considering each set that is in parallel as a cell with reference to the BMS? I was under the impression you have to monitor each 3.2V pack.
Every parallel set is called a supercell, the voltage between them can never vary. If any one of them starts misbehaving, it will pull the others down with it and the controller will shut it all down.
@@EverlandersHave you ever wanted more than the 100amp rating on your ElectroDacus. Videos are top-notch.
We've tickled the 100amp rating a few times, but the SBMS100 can actually do 120A all day long... and as I can't possibly fit any more solar, I've never wanted more controller...
Where did you get your batteries? Any tips on buying batteries in BC, Canada?
store.easpower.com/products/calb-180ah-3-2v-cell
@everlanders where did you pick up the batteries from? (Canadian here thinking about lithium)
Hez!!! Got them here: store.easpower.com/collections/calb-lifepo4-cells
@@Everlanders Hi there! I am also looking for this. However, the link shows 48V batteries, is this what you use? Thanks in advance!
They are 3.2 volt cells, you can wire them in series to get the 12 or 24 volts as needed. Google series vs parallel.
@@Everlanders Thanks for the quick answer! I see, make sense now. So you got 360amp for about 1800 CAD? That is actually cheap, isn't it?
Yes, this was a few years ago.
Flex mount bumper?
Do you talk more about it in another video? Not sure what it does.
+Tim Roach It allows the frame to flex without imparting twist to the box. I talk about it in this video too, with diagrams. czcams.com/video/mIrPho5Diac/video.html
Our new video describes it in more detail. czcams.com/video/7_NlZw3lk3A/video.html
Can you earn money by providing links in the description to products that you use on the truck? I think your recommendations are reliable.
Sure, we could...
Nope
What are the dimensions of the battery box?
279mm x 284mm x 360mm
Thank you for the prompt reply. Is that width x height x length?
I didn't actually measure or make a blueprint when I made it, I just arranged the cells in a block that I liked and made the box to fit... I whipped it up in 10 minuets and got on with the day. The dimensions I gave above are assumed based on the cell size from the data sheet.
Height: 280 mm (11.02 inch)
Width: 71 mm (2.80 inch)
Length: 180 mm (7.08 inch)
Weight: 5.6kg (12.35 lbs)

Thanks for your help. Unfortunately for me nothing gets whipped up in 10 minutes, LOL.
Maybe make a video about battery management.
Your web site has a no content error.
Yes, Thanks. Not so much an error as I haven't made much content yet. I've really been focusing all my efforts into the build itself. I'm lucky if I get time to record some video... I did just post a new video of us hitting the road, if you're not subscribed, you can see it here: czcams.com/video/N-E6btAcVAs/video.html
Dude, you need a bigger bank. 360 is not a lot. that's like average for a build. You need at least 700 to be safe. Especially on days with no sunlight. Shouldn't weigh more than 160 lbs which is like an average person.
I'd love to have more... But we rarely dip below 75% SoC so we're doing fine... We sold our house and currently living full time in our rig in Mexico... So we're always at 100% by 10:30am
@@Everlanders Oh ok that's very cool. And that's crazy though I would never tell anybody to actually like live full time in there build though but that's crazy cool and adventurous. Do you guys have a like a form of washer and dryer in there? Because I wanna do a chevy G20 van build that accommodates a washer and dryer for convenience. I mentioned it in a video I did about electric pickup trucks last month but a full video on it is yet to come. Your overlander reminds me of the earth romers. Dope build.
360 amps lithium has 300 amps usable, lead acid yes you would need 6oo-700 amps. and lithium needs 50% less power to recharge than LA. You can run AC for 6-8 hrs a day with this set up and still cook and wash.
@@1sheinz yeah that's if you're comparing. I'm not comparing I'm just saying in general 700 with lipos is a good place to be. Especially if you're not big on solar. Of course it depends on your power consumption. I'm definitely a power hog. I want 1280 for my van. Shouldn't weigh more than 160lbs. Shouldn't cost more than $1700.
Vince Abednego would you mind sharing your source for 700 Ah for $1,700.00?!
