The LI-BM500 Smart Battery Monitor provides accurate voltage, current, and capacity measurements for battery systems, especially those in solar power and off-grid applications. It uses a 500A current shunt for precise measurements, and it’s display can show battery capacity, capacity percentage, voltage, current, power, and time remaining. The monitor can be controlled and monitored from a Smartphone via Bluetooth, making it easy to view data on the Android or iOS app.
