This is my third home made battery pack, (if count the original pack, it is the fourth pack of the bike.), It is use 44 (11S4P) Samsung INR18650MH1 battery.
I accidentally connect the battery wire in wrong direction and burn the XT60 connector immediately, fortunately the BMS seems survived, and ebike still working. It could be a very expensive mistake.
Three different battery used for my three set of battery pack. From top to bottom are LG HG2 (LGABHG21865), Samsung INR18650-35E and Samsung INR18650MH1
