This project uses a four-forty 12S BMS board and a particle photon as a BMS for a 12S lithium ion battery. Included in the project are the following features:
- isolation of low from high voltage systems
- web connectivity (not fully implemented but hardware supported)
- current measuring
- cell level voltage monitoring
- low and high voltage cutoff
- 30A maximum current rating (depends on relay used)
