Lithium Battery Activation
REGO 12V 60A MPPT Solar Charge Controller has the activation function of lithium battery.
Lithium batteries may enter sleep mode when the in-built protection is triggered. In such case,
the charge controller provides a small current to reactivate the sleeping lithium battery. The
lithium battery can be charged normally after successful activation.

Operation Conditions
1. Set the battery type of the charge controller to LI. For details, see
2. Ensure the output voltage of the solar panel should be equal to or greater than 16V.

Operation Logic
1. In lithium battery mode, the controller automatically enables the activation function and
provides a constant voltage of over 13.6V to activate the lithium battery.
2. After activation for 1 minute, the controller temporarily stops activation and detects the
battery voltage again. If the battery voltage is no less than 9V, the controller will automatically
turn off the activation mode. Otherwise, it will continue to activate the lithium battery.
