Charging current/voltage for lipo batteries

Charging at 2C is fast charging, you should not be doing that "the whole way", see my remark about fast charging. Even when fast charging the current must go down when the battery is getting fully charged. If you don''t, the battery will overheat and might start smoking but for sure you will stress it and limit its lifetime.
