50.4V 51.8V 60V 14S 45A Lithium ion Li-ion LiPo Polymer Battery BMS PCB System

16 May 2016

Basic and decent

Hand soldered with variable quality control. The fuses are bigger then the traces, meaning the board will fry before the fuse blows... Easy to fix with some more soldering on the back around the FETs. The 14S version uses only 6 FETs, not the pictured 8, and does not use the last balancing trace on the board, but otherwise they seem identical. Uses 032N06N3 "OptiMOS" from infineon. I'm sure the board could use a heatsink when appraching 40 Ampere, and I plan on mounting my own at the FET screws. Recommended for lighter amp batteries or if you feel up for modding it yourself.
