What batteries can I use with this charger?
This charger is only to be used with lithium-polymer or lithium-ion batteries that are 3.7V or 4.2V only. Batteries are connected via the 2-pin JST connection, for which a cable is provided. Two LEDs help you determine whether the battery is currently charging (red), and when the battery is fully charged (green).
Takes care of your batteries
This charger works in three stages. It firstly performs an initial preconditioning charge which will help prevent improper charging of depleted batteries. After preconditioning, the charger offers a constant-current fast charge to reach full charge as quickly as possible. When the battery is full, this charger will supply a trickle charge to keep it safely topped up.
If you are looking to store your batteries for a period of time, it is advised to store them with a charge of 50 per cent. This will help ensure the maximum overall life of your battery.
