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
