Yeah that was my main concern
A little bit goes a long way, a thin bead down the entire length of the cell if you work it into that gap will be quite secure
You did not waste your time, because what if one of them was 1.75V?
Now you know that they were all good at the beginning. If there is ever troubleshooting later, this is a variable you can cross off the list.
The second life storage forums has a lot of info about powerwalls https://secondlifestorage.com/
love it, thank you!
First try cleaning up a battery I welded the nickle on the wrong side
Is this good enough?
This 0.22mm is tough to get off with out shredding it Iām tempted to throw away all my 0.15 stuff away
What people think of the clean up any thing I could do differently/better?
what enclosure is that?
Its from Dave. lol
Nice big tub! i like it. i am working on my first battery for one of his enclosures, them things fit a lot of batteries! also your pack looks really good!
Thanks man. His enclosures are prone to cracking and the battery being pretty heavy Iām planning on mounting it to the deck.
Making a charge-n-ride so Iām never the small battery at group rides again, @Arzamenable
-
set up the converter to put out 50.4v. No load voltage was 50.4, dropped a bit when charging at 7.5 (!) amps.
-
pot the board in epoxy so the bits donāt shake off during a ride

???
What buck/boost circuit is this?
I will legit depend on mine to run over head leds, cellphone tower repeater, and MISC phone charging in a dark medical in a tent for 6 days.
This one yeah?
Haha, yeah, I have that sweet lil converter on order, will definitely get that going as well.
this one is a 600w unit available on amazon or wherever. I have had it sitting in my drawer for months.
It was @Skatardude10 that originally inspired me with the power tool range extender.
Only problem I had with mine was that top mosfet to the right of the pots in your picture, I didnāt pot that one for some reason and it broke loose after about 7 months of riding with it on my board. I heard it clinking around, soldered it back on, potted that one extra componentā¦ Still works great. I donāt ride with mine anymore, but if I think iāll need it, iāve got mine packed in a pelican case with larger batteries that I can strap on as needed.
For $13, itās been bullet-proof (with that little bit extra TLC of course).
Haha, I remember you saying something about that, and I have had caps pop off an esc riding so yeah, I potted the whole thing. I donāt think I will even be able to adjust it anymore. YOLO.
Thats what she said.
