Re: Generic-Chinese-Bluetooth-BMS-communication-protocol

Hi, @simat : Thanks for the work. I built a little test setup for the "China BMS". The data is read with a Pi-Zero running gatttool. With the 3 read commands, I found a lot of things and did a little tinkering: Packvoltage: 52.80 V Amperage: -.23 A BMS Name: LH-SP15S001-P14S-60A Cell#: 01 02 03 04 0...

Good Morning. I am on a build of this great mod here. The over voltage protection is adapted already and I can go from 10 to 14,4 Volts under full load. Now I'm working on the current limiter. Because of the low Quality of the "shunt_connections.jpg" photo, I don't know where exactly to solder. Here...
