Strike Systems Li-Pol Battery 7.4V 1300mAh Nunchuk T-Dean — Black

Li-Pol battery in nunchuk format, 7.4V and 1300mAh capacity with a T-Dean connector, designed for airsoft guns without a MOSFET or ETU. The nunchuk configuration — two cells connected in series by a flexible cable — fits into the tight battery compartments of AEGs with a fixed stock or buffer tube, with no need for external pouches or dummy PEQ boxes.

Compared to traditional NiMH batteries, Li-Pol chemistry delivers a more responsive trigger feel and a more consistent rate of fire at the same remaining charge: the discharge curve stays flat for most of the cycle, so the last bursts are comparable to the first. Performance in cold conditions is more stable than NiMH, which loses significant capacity at low temperatures. The overall length of 130 mm allows installation in many standard battery compartments without any modifications to the airsoft gun's body.

The battery features a separate balance connector: this is the correct point for charging with a balanced Li-Pol charger, which monitors each cell individually and is essential for both safety and long-term battery life. The T-Dean connector reduces contact resistance compared to Mini Tamiya, with lower energy loss during sustained fire. Please note that Li-Pol batteries require a charger compatible with this chemistry — using a NiMH charger causes irreversible cell damage.

Key features

• The 130 mm nunchuk format fits into tight AEG compartments with a fixed stock or buffer tube without additional accessories, keeping the external appearance of the airsoft gun unchanged.
• The 7.4V voltage is compatible with airsoft guns without a MOSFET or ETU, with no risk of overloading the original contacts.
• The 1300mAh capacity with a continuous 25C discharge rate supports extended sessions with a stable rate of fire.
• The T-Dean connector lowers junction resistance compared to Mini Tamiya connectors, reducing energy loss during sustained bursts.
• The integrated balance connector makes charging safe and efficient with any compatible balanced Li-Pol charger.
