these battery's are a pain in a but to take apart took me forever first time maybe can help someone
Specs :
SAMSUNG INR 18650-32E cells 9p10s
pack can draw 50a continuous or 100a peak
27ah at 36v
top
side
discharge port
charge port
now lets begin
there's 12 Philips screws to take out first
then make small cuts in each corner with a small saw so you can insert a screw driver to prise it open in each corner its filled with silicon or something similar and open it from the back end will come apart eventually
then start picking off all the crap on it comes off easy just enjoying to get to all the holes under it
there's 16 philips screws in holes marked i used a drill bit to clear em out can be a pain sometimes
take them 4 screws out leave the rest
take small saw and make a slit on each side all the way true dont worry cells got thick plastic around it won't damage them
then snap the back down will snap easy
IF YOU CANT PULL APART YOU LEFT A SCREW OUT
pull the sh*t of and around the leads and disconnect power cables
pull out the old bms and you done
put in a new bms rewrap and get a charger
hope it helped someone out
YOU CAN BYPASS BMS BY SOLDERING NEGATINE FROM BATTERY TO OUTPUT BMS WILL BE INACTIVE
