dang dude thats really odd. I have 4 more of these if you need em
the bad cell was down to 1.996v. The rest of the group is at 2.5v. gonna charge em under supervision this weekend.
Guessing by how the the other cells recovered I’m optimistic. But ,
Thanks dude. I’ll grab those off you just in case though.
Was talking to pooky and we think I’m dumb. I don’t get any moisture overnight but I left them outside and maybe just got just enough to cause it. That or it’s just a factory dud.
Either way I’m terrified. Battery.Building in an apartment is just not nearly as fun.
The culprit has been evicted
Sorry I don’t have more intermin pictures.
Here’s the final product though. Basically just soldered on wires and wrapped that bitch up
Last battery like this I build for a while. Battery building seems to make me very anxious haha
Dude, how much does that weigh?!?! Holy smokes!
Don’t have a scale but probably 30 lbs.
Daaaaang dude! Thats alot of juice! 19amps!!! Watch the heat on thay battery lol! My 12s8p p42a heats up a bit while charging at 8amps.
I’ll probably charge at 10 amps only. Though 20 amps is still just .5c per cell…
Can’t wait to try this baby tomorrow morning
lol is this why you’re gettin leaky cells?
Heyyyyy
That cell leaked all on its own. Before I even charged
hahahah suuuuuure
That bms sometimes limits the current.
It’s probably truly outputting 20 but the bms is limiting for safety
Literally looks like a bomb
Of the power supply is doing 20 , and the BMS is limiting 16 to the battery. Then somewhere 4amps*50v is 200w is going poof and that’s no good. 200w of poof is a looot
