Rebel Battery - 350mAh Li-lon 7.4V HPA Micro - JST

Rebel HPA Micro 7.4V 350mAh Li-Ion: The Next-Gen HPA Power Solution

When every millimeter of space in your grip or stock tube counts, you need a power source that is as efficient as it is compact. The Rebel HPA Micro 7.4V 350mAh Li-Ion Battery represents the latest evolution in HPA electronics power, offering higher energy density in a rugged, ultra-slim form factor.

Built with high-performance Lithium-Ion (Li-Ion) cells, this battery provides a consistent, reliable discharge that keeps your Fire Control Unit (FCU) and solenoid running flawlessly without the "puffing" risks often associated with traditional LiPos.

Why Choose Rebel Li-Ion for HPA?

In a specialized HPA build—like a Wolverine MTW or a PolarStar Jack—the battery's job is to provide instant, repeatable energy to the solenoid. Our Li-Ion cells are chosen for their stability and long-term durability.

• High-Capacity Micro Footprint: Despite its tiny 16mm x 16mm x 56mm dimensions, we’ve packed 350mAh of capacity into this cell. That’s extra "insurance" for those long Milsim ops where you can’t get back to a charger.

• 35C Discharge Rate: Don't let the small size fool you. The 35C rating ensures that even high-speed "spamming" of the trigger in semi-auto won't cause a voltage drop to your FCU.

• Rugged Construction: Li-Ion cells are naturally more resilient to physical impact than soft-case LiPos, making them the perfect choice for the rough-and-tumble environment of a CQB arena or woodland field.

• Standard JST Connector: Direct plug-and-play compatibility with almost every HPA engine on the market.

Technical Specifications

The Specialist’s Choice

This battery is the ultimate "problem solver" for builds with extremely tight tolerances. If you’re running a sub-compact PDW or a specialized grip that leaves almost no room for wiring, the 16mm square profile of the Rebel Micro allows it to slide into gaps where wider batteries simply won't fit.

Tech Tip: Because Li-Ion cells handle being left at full charge better than LiPos, this is the ideal battery for players who want a reliable "grab-and-go" setup. However, we still recommend using our Rebel RBC03 charger to monitor cell health and ensure your 350mAh is always topped up for the next skirmish.
