Strike Systems Li-Po Battery 11.1V 1300mAh 20C T-Dean — Black

Li-Po battery in Crane configuration for AEG airsoft guns, made up of three separate cells measuring 130x22x22 mm each, connected together and designed to fit inside the tubular Crane stock of M4/M16-type replicas. With a nominal voltage of 11.1 V and a capacity of 1300 mAh, it suits players who want enough runtime for a full game session without adding unnecessary weight to their airsoft gun.

The 20C discharge rate defines the maximum current the battery can deliver relative to its capacity: on this unit, that means up to 26 A peak — sufficient for standard motors and the vast majority of ETUs currently in use. The T-Dean connector has lower contact resistance than the classic mini-Tamiya connector, resulting in less energy loss, particularly during bursts. If the airsoft gun still uses the original connector, it is advisable to upgrade it before installation. The integrated balance lead allows charging in balance mode, which is essential for keeping all cells at the same voltage and extending the battery's service life.

Li-Po batteries require careful handling: they must be charged exclusively with a Li-Po-compatible charger, preferably inside a fire-resistant charging bag. It is important to stop using the battery when the rate of fire noticeably drops, or when the ETU signals a low-charge or fault condition — continuing to discharge below the threshold causes irreversible cell damage. Store the battery in a cool, dry place, away from direct sunlight and extreme temperature fluctuations.

Key features

• Three-cell Crane configuration (130x22x22 mm each): fits inside the tubular stock of M4/M16 airsoft guns without structural modifications.
• Voltage 11.1 V and capacity 1300 mAh: sufficient for a complete session on an airsoft gun with a standard motor.
• Discharge rate 20C: delivers the current required by ETUs and high-draw motors without dropping out during bursts.
• Low-resistance T-Dean connector: reduces energy losses compared to traditional connectors; compatible with most airsoft guns already fitted with T-Dean plugs.
• Balance lead included: enables balance-mode charging to keep cells even and extend battery life.
