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 system measures important data like cell voltages, cell temperatures and in- and outgoing currents. It also balances all cells to the same voltage during charging. The BMS supervises the whole battery pack and has two signal relays to indicate “allow to charge” and “allow to discharge”. These signal relays can control chargers and inverters with “enable”/”disable” signals or by connecting an energy efficient power relay to the signal relay. An example is the 123\SmartRelay. Easily connect your phone to the BMS using Bluetooth to see relevant information including state of charge, energy consumed, energy stored, in- and outgoing current, cell voltages and temperatures. With 123\SmartBMS, your battery pack is in safe hands.
