The 8256 Li-Ion Battery is a compact support power solution developed for use in HPA airsoft systems requiring a small, lightweight external power source. With a 7.4V output and 350mAh capacity, it is optimised for powering FCUs, regulators, and electronic control modules rather than driving AEG gearboxes.

Its cylindrical cell format, measuring 57mm in length and 14mm in diameter, allows easy installation into buffer tubes, grip compartments, or dedicated HPA battery housings where space is limited. The slim profile supports clean wiring layouts and minimal bulk in performance-focused builds.

Fitted with a JST connector, the battery integrates directly with compatible HPA electronics without modification. Using stable Li-Ion chemistry, it delivers reliable voltage output and consistent operation for players running HPA platforms who require dependable auxiliary power in a compact format.
