2024 available? 100ah+ Lifepo4 UNIT that fits under driver seat

[syncrodoka]

It is weird that the holes for the plastic positive terminal cover that comes on group 41 batteries are missing. Battery shorts are bad.

I like the little caps on the terminals.

Just installed today. Yes it fits! Note to GW: Can you make the terminal posts just slightly shorter? Otherwise, great!

I’ll get pics of interior wiring posted as I can .

I think instead of 45 from top, side holes in the main case about 1/2-3/4 inch below the top woudl do it .

I replaced the stocks battery bus bars ( laminated copper sheet bound with heat shrink ) with 6 awg. To lead out of box. It’s trivial mod .

I printed the top from petg. I’m not happy with it really, I’d like one piece . I’ll probably machine that . But as is , it works .

Impressive job! I would like to do something similar if I can.
I wonder if you could drill the holes for the cables at a 45 degree angle so the cables wouldn't need as sharp of a bend on the outside.

Any photos of the cable connections you made inside?

Hi,

Been working on getting my aolithium to fit drivers side . I printed a new lid, two part as my printer can’t do it in one . There’s a bridging party under to glue together, I’ll probably machine one part version from poly e.

The gland nut things you see, first go round I made them too tall. Bench pics show shorter. I’m tempted to drill side of case and lead cables out that way .

But, it fits under the lid .

Excuse the wiring mess, that’s all being tugged and moved from my previous aux battery set up

progress on an easily repeatable non-bootleg direct-fit under-seat 100ah

should have the first pair ready "Real Soon Now"

[metahacker]

those aolithium 100ah bluetooth batteries are incredible, so cheap and SO good

they can handle 1C (100a) charge and 2C (200amp!!!!) discharge rates (notice the huge copper at those terminals).

i have ran them since they first came out

i have 2 x 100ah aolithium batteries in each of my 2 bay window campers
and 4 x 100ah aolithium going into my new vanagon build

and i had another 2 that went to my shopmate (e.g. from my bus, and then got replaced with new ones) when he needed batteries for his toy hauler trailer in a panic/jam right before going out to glamis .. still working great for him too ...

so techincally, ive bought 10 from those guys

they have been awesome to deal with - i received 1 doa and they sent a replacement right away with no fuss and told me to keep the old one.

when i first ordered my 2nd pair for my other bay window, they immediately called me with an engineer in china on the phone to make sure it was going to work..i believe they had updated the firmware between my 2 first orders and wanted to check in. how often do you see that kind of behavior from a company nowadays? so awesome.

i am working on a replacement lid so that they just drop in on the vanagon normal spots behind the seats, just got the first attempt back from laser cutting. hoping to have it finalized very soon, should make for a VERY easy 200ah of lithium in the vanagon typical battery holders

my t3 is a diesel so i already had a battery tray in the engine bay...also a 2nd aolithium fits perfectly (sideways) behind the taillight, right next to that tray, with no effort.

so, 200ah in the bay and 200ah behind the seats.
should be an easy path to 400ah with zero loss of storage space.
anxious to see how it does...and how my VW MK4 "250a" alternator feels about it :)

also..... i ran those two different dual aolithium setups in multiple years of DAILY driving on both my bay windows starting in February 2022 - both with high amp alternators (~160a on a type 4, 270a on a subaru), no isolator/split charge/DC-DC crap, just raw dog wired straight together and straight to the alternator running the camper loads (e.g. 12v fridge/water pump/heater) and regular vehicle wiring together ..

no issues at all, unlike the renogy batteries (and several replacements they sent me) before them (although they were good enough to refund my original purchase price which was almost like an investment, being that the old renogy price was much higher than the new aolithium price) ..

and i even ran the aolithium pair in my 78 riviera from san diego to brooklyn new york, toronto, etc and back...through terrible rains etc, with them both mounted in the engine bay. (the renogy batteries couldnt take the moisture, despite their IP-rating...those RJ45 ports never sealed properly)

cheaper than an optima battery yet LiFePO4 with bluetooth BMS monitoring built in. perfect size for T2/T3 (soon, with a little help). impossible to beat.

P.S. i like this app better than the one aolithium provides
https://apps.apple.com/us/app/xiaoxiang-bms/id1375405426

it's a very common off the shelf/standardized BMS they are using on the Aolithium...the "JBD"

here's a teardown from a dude who knows what's up

Link


and here he runs a 200A+ sustained load on it from full until its flat, and it doesn't even catch on fire ;-)

these same batteries were like $650 not long ago

That's exactly what I did, I ordered cells a month ago....

Are these going to be affected by the increased tarriffs? Figuring probably will!

They are back. The ad looks different so maybe there have been changes? Still a very attractive price point though.

Nice work.

The wasted space inside the battery boxes is annoying. It's good that the space obsessed have options to either cut the box or build a DIY battery.

Respect for cutting the new battery rather than the Syncro.

Well everybody, It was reported to me on Samba that this thing fits, but a better description would be that it *almost* fits. i have been here before and learned a long time ago on other vws to modify the tech, not the bus, so i dont regret it in the future that i hacked up a classic for a trendy new piece of tech.


So this AO lithium ion battery is a very close fit, but i saw on here one solution of someone hammering away at their battery box to gain the couple millimeters and opening a body seam in the process and decided i didnt want to go that route. I am currently prepping the car for paint and dont want to invite new problems since its Syncro and is super rust free, so i started looking at this battery....

There's an inch or more of clear space above the control panel and heat dissipator inside.
So i pulled out the tablesaw.... and the lid of the battery...
and flipped the part i cut off to provide lower profile in the battery compartment.

Then used the soldering iron as a plastic welder....at 750 degrees worked best.

It is hooked up to solar and so far works fine. i do not however have loads on it to monitor for any temperature impacts to my 'adjustments'. The battery now fits with 3/4" inch to spare, mounted sideways. room for soundproofing on the wheel well box.
Voided the warranty? surely. But i am invested in this battery 169 dollars ( a lot less than the car investment) . It seems like a responsible abuse of technology.
Cut the syncro? Nope.
Whenever this battery dies, the next generation from AO or another manufacturer will surely be smaller. I think they already have the next gen out, and that is the reason for the fire sale on these units.

Hopefully this helps others not chop up their vans to make this work, but may be dangerous and irresponsible attack on a plastic box. It is now kind of a hybrid of unit battery and custom set up. i am not a battery nerd i just wanted something for a reasonable price with good capacity for a house battery that fits under the drivers seat, as the title of the thread suggests.
