The Rich Solar RS-BC12V20 is a 12V LiFePO4 battery charger designed to charge compatible lithium iron phosphate batteries from a 100–240V alternating current power source. It outputs 14.4V ± 0.2V direct current at 20A, giving buyers a clear charging rating for properly matched 12V lithium battery systems. A 50A Anderson connector, M10 battery terminals, LED status indicators, and a tough aluminum shell support straightforward setup and practical use. The charger uses a documented 3-stage charging process: pre-charge, constant current, and constant voltage. Built-in protection for over-temperature, reverse polarity, short circuit, and over-voltage helps support safer charging when the unit is used according to manufacturer instructions.
The RS-BC12V20 provides 14.4V direct current output with a 20A charging current for compatible 12V lithium iron phosphate batteries. Its 100–240V alternating current input range supports use from standard power sources within the stated voltage and frequency limits.
The charger is documented with pre-charge, constant current, and constant voltage charging stages. This staged approach helps support controlled charging, including recovery support for compatible battery management system-protected batteries that need a proper charger connection.
The RS-BC12V20 includes M10 battery terminals and a 50A Anderson connector for connection to compatible battery setups. LED lights indicate standby, charging, full, or error conditions so users can quickly check charger status during operation.
A durable aluminum shell and fan support heat management during charging. The manufacturer lists over-temperature, reverse polarity, short-circuit, and over-voltage protection for the RS-BC12V20, helping protect the charger and connected battery when used correctly.

The RS-BC12V20 gives compatible 12V lithium iron phosphate battery systems a dedicated 14.4V, 20A charging source from 100–240V alternating current input.
LED status indicators, M10 terminals, and a 50A Anderson connector help make charging status and battery connection easier to manage.
