I was gonna install an xt60 port, plenty of empty space in the housing
Great idea. Look forward to seeing your modifications.
if you took out the BMS,add a charge only 13s bms, it can fit a dual escā¦
haha Iām hoping to get my ESCās inside the deck asap.
It would be cool to integrate basically an entire esk8 power system into the battery. Then make a top cutout board so it can sink in and be less thicc. Quick swap an entire electronics system would be nice.
That would be quite the cutout!
Seems like they are now sold out.
@Scepterr do you think you could figure out how to use the BMS on the Batteryhookup 48 A123 cells?
hmm that looks considerably more complicated, can you get some of the IC model numbers
Didnāt order it yet, as being able to use the BMS would def make the deal worth it for meā¦
Maybe they can share the info youād need if you contact them?
theyāre not gonna bother with that, know anybody who has one?
@Fosterqc did you end up getting your A123 LiFePO4 batteries at Batteryhookup?
@deucesdown you got your A123 cells without this peculiar BMS, right?
i watched the video, teardown doesnāt look that tedious. and that 10% discount code does work. i gotta think about it, and look for a seahorse/pelican case that fits
tempting!
Yep got em. Havenāt touched them due to needing a power supply for my kweld.
Mine are new old stock. Single cells. I have had good luck using the smart bms with them. I have one 15s2p pack with smartbms.
Just took apart one of the cells today. So there are two pouches in each black box making it a 13s 2p configuration.
how was the process to take em out? how destructive is it?
Very destructive, I definitely damaged the internal laminations getting them out. They have double sided tape on both sides of each cell, and the black plastic seemed to be either glued or plastic welded together so It doesnāt open easily. It might be easier if you warm them up before but not worth the effort.
Now i think Iām going to over charge them and see what this STOBA can do when punctured .
I admire your commitment to science. Please make sure you maintain enough motor functions to come tell us how it went
@Scepterr I was trying to wire up one of my batteries for an Ebike. The jumper you showed worked as far as giving a readout of the full battery voltage. But when I plugged it into my VESC it quickly turned off (after 2 or so seconds of power on). Almost like it doesnāt allow a load on the BMS, and those pins just allow charging? Did you try discharging it more so then connecting a multimeter? if I canāt get it figured out I plan to just bypass the BMS
jumper the other pair, see if that does the trick
so both pairs jumpered
Okay, iāll try it. Thatād be cool if one controls charge and the other discharge.
