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.

This is a great item. Easy to install with the wiring diagram that comes with it. It's rated at 40A and its all in all great Battery Management System. I would recommend this item for anyone wanting to use 51.8v-58.8v fully Charged for that extra top speed on any 48v controller ebike.

I am using this BMS on a 52v 25ah Li-ion battery for a 48v 1200w Ebike and has not given me any problems, pulling a maximum of 35amps in my case.

Ran daily for 10months but this charger would not last being transported daily to work within the given warrantee. Best to get a Luna or even an expensive Grin Satiator.
