BMS Logic 2R
Measuring module
Modular BMS for 24-2000V batteries
BMS Logic 2R is an updated version of BMS Logic 2.0 and delivers next generation features in the same form factor.
It determines voltage and temperature of the battery cells and does passive balancing of the cells on a command from the BMS controller.

- 4-12 cells
(accuracy ±3mV) - 2 temperature sensors
- Passive balancing (350 mA @4.2V)
- RS-485 (3500V RMS isolation)
Compatible controllers: BMS Main 2R, BMS Main 3
Compatible auxiliary modules: BMS Repeater
