LG 18650 C2 2800mAh (Orange)
I could not find any specifications on this cell.
This battery can be charged up to 4.3 volt.
The batteries has a high voltage, even at high loads. The capacity is below the specified capacity.
These are unprotected cells.
Most LiIon chargers can only charge to 4.2 volt, a possibility to get 4.3 volt is a hobby charger with adjustable charge voltage (Like iCharger).

Reducing the charger voltage to 4.2 volt reduces the capacity with about 200 mAh.
LG does make very good cells and the higher output voltage when loaded can be interesting for some applications. But it requires a special charger.
