Airsoft Battery should only be charged with the chargers as they are specifically designed to work with the specific voltages required by the battery.

Different battery types have different chemical configurations, and require certain chargers to charge them. Charging a battery with the wrong charger can cause damage to the battery and charger, and can cause fires and further damage. Please ensure that before charging you double check that you are using the correct charger.

If your charger supports multiple battery types always ensure that it is on the correct settings before starting the charge.

We always recommend charging LiPos and other batteries in a charging bag.
