LiPo 7.4V 350mAh 25C HPA JST Impact Arms Battery
In HPA setups, people often talk about air, regulators, or pressure… but without a battery, nothing happens. It powers the FCU, controls your HPA engine, and ensures consistent responsiveness. Clearly, choosing a reliable model is essential.
This Impact Arms LiPo 7.4V 350mAh 25C battery is specifically designed for modern HPA setups. Ultra-compact, lightweight, and stable, it fits easily into minimalist configurations without adding weight to your replica. It’s the kind of battery you install… and completely forget during the game.
With a 7.4V voltage, it perfectly matches the needs of HPA systems. No need for excessive power, just clean and stable supply for the FCU. Result: consistent cycle, excellent responsiveness, and predictable operation.
Its 25C discharge rate ensures smooth system power delivery. With 8.75A continuous and 17.5A burst, it provides more than enough to efficiently power a PolarStar, Wolverine, or equivalent HPA engine.
The JST connector, standard on many HPA systems, allows quick and direct installation. No modification, no adapter… plug it in and you’re ready.

FAQ LiPo 7.4V 350mAh 25C HPA JST
What is a battery used for in an HPA system?
It powers the FCU (Fire Control Unit) that controls the HPA engine cycle. Without a battery, the system will not operate even with air.
Why choose a 7.4V battery for HPA?
HPA systems require stable power, not high voltage. A 7.4V battery is ideal to ensure reliable FCU operation.
Is this battery compatible with PolarStar or Wolverine?
Yes, as long as your system uses a JST connector, this battery is compatible with most HPA engines.
Can this battery be installed in a buffer tube?
Yes, its compact micro format is perfectly suited for installation in a buffer tube or small compartment.
Is 350mAh sufficient for HPA?
Yes, HPA systems consume very little energy. A 350mAh battery generally allows multiple game sessions.
Is the 25C discharge rate sufficient?
Yes, the FCU requires very little power. 25C is more than sufficient for stable power delivery.
Do you need a specific charger for this battery?
Yes, like any LiPo battery, it must be charged with a LiPo-compatible balance charger.
