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.

SmartBat Pro is an enhanced Bluetooth APP based on "SmartBat" Bluetooth APP. Beside previous functions such as monitoring battery status, processing battery information in real time, it can exchange information with external devices such as revise BMS settings if the built-in BMS support the function. The most fascinating feature is that SmartBat Pro bluetooth APP can read the information of some popular batteries in the market too. The detailed functions are as below, 1. Display real-time voltage , current, power, internal resistance and other parameters in the form of panel and digital display; 2. Display the real-time voltage and alarm status of all individual batteries. If the alarm or protection value is triggered, an alarm is generated. Charging switch, load switch. 4. Compare each data of the cell and the voltage difference. Maximum voltage cell Minimum voltage cell. And cell balance display 5. Cell temperature warning. Real-time alarms are generated for overtemperature, short circuit, overvoltage, and undervoltage 6. Record the warnings that occur at each moment. 7. Compatible with different models of products 8. Revise battery settings on-site (depend on BMS and password needed) SmartBat Pro will help you enjoy your battery.
