Battery Shunt Renogy 300 BT

Battery Shunt Renogy 300 BT (Smart Shunt 300A) - battery monitor with Bluetooth

Renogy Shunt 300 BT is an advanced battery monitor (shunt) for precise measurement and analysis of power bank performance.
It is compatible with many battery types, including lead-acid (AGM, GEL), LiFePO (LFP), Li-ion and Ni-MH.
It allows remote viewing of the state of charge (SOC), voltage, current and temperature in the app. DC Home and integration
with the Renogy ONE ecosystem. Additionally, it records historical data and provides alerts on abnormal conditions, helping to protect
batteries and optimize the entire power system.

Key benefits

• Universal compatibility - works with AGM, GEL, LFP, Li-ion, Ni-MH and other types of batteries.
