What happens if you charge a lithium ion battery below voltage?
Going below this voltage can damage the battery. Charging Stages: Lithium-ion battery charging involves four stages: trickle charging (low-voltage pre-charging), constant current charging, constant voltage charging, and charging termination. Charging Current: This parameter represents the current delivered to the battery during charging.

Can You charge a battery with less current?
You can always charge a battery with less current. Heck you can even not charge it (no current).
