123\SmartBMS is an easy to use yet advanced, modular BMS to keep your lithium batteries in perfect condition, increasing the lifespan of the battery pack.

The BMS measures important data like cell voltages, cell temperatures and in- and outgoing currents with the two included high accuracy, dual range current sensors. By measuring both currents independently, it is possible to know the current production and consumption. The system balances all cells to the same voltage during charging.

Two integrated signal relays with potential free contacts can be used to switch enable/disable signals or power relays to control the power to chargers/solar regulators and/or inverters.

Easily connect your phone to the BMS to see relevant information including state of charge, energy consumed, energy stored, in- and outgoing current, cell voltages, cell temperatures, SoC history of the last week and error history.

For simulator mode: the PIN is 1234
