The Swiss Arms LiPo AN/PEQ 11.1V 3600mAh 25C battery is designed to power electric airsoft guns ( AEGs ) that require a high-performance LiPo power source.

With a voltage of 11.1 volts (3 LiPo cells), it improves motor responsiveness, rate of fire, and consistent performance compared to conventional NiMH batteries.

Its AN/PEQ format allows for installation in external PEQ housings or in the compartments provided on certain tactical airsoft guns.

Technician's Review

★★★★★

High-performance battery suitable for AEGs equipped with a brushless motor and wiring compatible with 11.1V LiPo batteries.
The 3600 mAh capacity provides excellent runtime for long days of play.

⚠️ Workshop recommendation:

• Use only with a replica designed for 11.1V LiPo.
• Check for the presence of a MOSFET or electronic protection system to limit contact wear.
• Always use a LiPo charger with balancing.
• Never leave a LiPo battery completely discharged.

History of the Technology / Brand

History of Airsoft LiPo Batteries

LiPo (Lithium Polymer) batteries have gradually replaced NiMH batteries in airsoft thanks to:

• higher energy density,
• lower weight,
• better discharge capacity,
• faster motor response.

They have become the standard for modern AEG replicas, particularly those equipped with MOSFETs and electronic controllers.
