Hi,

1) Please refer to the battery charging specs provided by the battery vender.

2) The device will charge the battery below 3.2V when charging conditions are met. But the user may disable charging if needed.

3) The charger device automatically terminates the charging cycle when the charging current is below termination threshold and charge voltage is above recharge threshold.

4) User battery fuel gauge or battery monitoring circuitry.
