Built-in three-segment curve charging:

① constant current charging stage, when the battery voltage is greater at 8V, the controller enters the constant current charging mode, and the maximum charging current is 10A (note: The solar panel should be able to provide the power at this time under the current sunlight);

② constant pressure full stage, when the battery voltage continues to rise and approach14.5v enters the constant voltage charging mode, and the charging current gradually decreases. When the charging current decreases to 1A, the charging ends to trickle floating charge.

③ trickle floating charging stage, controller constant13.5V continuously replenishes the small current of the battery.
