First of all this is an original LG 3.7V battery.
The capacity is of 3.000 mili-amp (mAh).
Because of that this battery hast the highest capacity for a true high-drain (20A ) cell.
Furthermore the nominal voltage is standard for all 18650 batteries.
Therefore the voltage is of 3.7V.
Another factor is that A 1.5A fast charge is good.
But remember that hence to that it will decrease the cycle life.
Last factor the battery comes in chocolate color.
