New models of Gotway BMS don’t have the infamous power cut mosfets, Gotway has finally been aware of the danger of powercut and has made the right BMS for monocycles. Good !
Gotway, recent models, no shunt needed. The Gotway 680Wh power consists of 2 paralleled 16S2P battery packs, each with its own BMS (see schematics), with a total of 64 cells of 2700mA ! A huge beast. Only one overvoltage protection mosfet clearly visible on the pictures, so no shunt needed. Source : vee73 of http://forum.electricunicycle.org/
