I would lke to start a list of hardware features for bms master board v3. Please quote this post and add your stuff at the bottom of the post. I'll start it off. The board will have all the features of V2 in addition to the below list.
1) Picbasic pro based 16F886 Master Chip with icsp
2) Picbasic pro based 12F683 Watchdog chip with icsp
3) Tellymate Video chip 38x25 Display with icsp
4) I2C Eeprom chip 64kbyte
5) Auto power off option once charging complete. BMS powers down after charge end. Save aux battery power. Possibly power BMS from main pack? Once BMS has turned itself off can't restart without operator input.
6) Two seperate charging relay outputs to control a home made two stage charger using 48v open frame power supplies.
7) 19200 baud in/out ports/feature for the home made controller interface. Greg
Possible delayed charge start to allow use of off peak electricity. Not sure hiw that will work with option 5
9) Remote display tx port
10) ?
