If you are looking for the biggest battery you can fit in an M4/AR-15 buffer tube this would be it! The 7.4v 2000mAh 15C LiPo Stick Battery from Electro River just about fits in an M4/AR-15 buffer tube, though we recommend you do not fully collapse the stock once it is installed.

The battery measures 12.6 x1.6 x 2cm and should also be suitable for top-wired AK AEGs and will fit in almost all fixed stock battery compartments regardless of the platform. The wire length between the connector and cell group is approximately 9cm and the continuous discharge rate is 15C with a peak discharge rate of 30C.

Special Instructions

If you are using this battery in an M4/AR-15 buffer tube we recommend being very careful when you collapse the stock. In most cases, the stock will no longer be able to collapse into its most compact position due to the size of the battery so we recommend leaving your stock in the second position to avoid squashing the cells.

Size guide

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.
