If you need a battery for your AR36 AEG or polymer handguard equipped M4/AR-15 AEG this one will do the trick! The 7.4v 1800mAh 20C LiPo Flat Nunchuck Battery from Electro River is a flat nunchuck style battery, also known as a "butterfly" configuration. Unlike other nunchuck batteries, this won't inside a crane stock and is more suitable for large polymer handguards such as those found on AR36 and M4A1 AEGs and will also fit nicely in most fixed rifle stocks.

The battery itself is a 2-cell 7.4V LiPo with a wire length of approximately 9cm between the cell groups and the connector, and each of the two cell groups measures 10 x 0.6 x 3.5cm approximately. The pre-wired connector is the common mini-Tamiya type and the continuous discharge rate is 20C, with a maximum discharge rate of 40C.

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.
