Product made to order generally delivered in 7/10 working days.
The LiPo 7.4V 300mAh 35-70C Battery for HPA (JST) from VB Power is the ultimate micro-reactor for your compressed air control units.

With literally microscopic dimensions (4 x 1.9 x 1 cm) and a feather-light weight of only 14 grams, it comfortably disappears inside any pistol grip. It guarantees instant solenoid opening thanks to a continuous discharge of 35C and scorching peaks of 70C!

Native for Premium HPA Systems (JST):
If you've invested in a high-level HPA engine, you know that its electronic control unit (FCU) requires a compact, reliable power supply with the correct connector. VB Power has created this gem by wiring it directly with the red JST connector, the absolute standard for Polarstar, Wolverine, and many other advanced FCUs. No more bulky adapters or homemade soldering: just plug it in and you're ready to dominate the field.
Micro Dimensions and Lightning Start (70C Burst):
Space management in HPA replicas is always a challenge, especially if you want to hide everything in the engine grip (Pistol Grip). This LiPo solves the problem at the root: it measures just 40 millimeters in length, 10 in thickness, and weighs only 14 grams. But don't be fooled by the "bonsai" size: its 300mAh at 7.4V are driven by a discharge of 35C continuous and a good 70C peak (Burst), guaranteeing the solenoid valve of your system the instantaneous impulse necessary to sustain extreme rates of fire (ROF) without the slightest delay.
Main Advantages
- Direct JST Connector: The mandatory choice to natively power Polarstar, Wolverine, and similar FCUs.
- Invisible Dimensions: 4 cm long and 1 cm thick, perfectly hidden in the tightest grips.
- Extreme Reactivity: 70C peak to activate the solenoids at the speed of light.
- Feather Weight: Only 14 grams, doesn't add an extra gram to your super-light setup.

Pro Maintenance Tips
PAY ATTENTION TO THE CONNECTOR (This is the JST!): We remind you to avoid incorrect purchases. This battery mounts the red JST micro-connector, typical of Polarstar or Wolverine systems. If your HPA control unit instead uses the white plastic connector (Mini Tamiya), do not buy this battery! Look in our catalog for the "Duel Code 300mAh" model which is equipped with the Tamiya.
Want to build your "Monster" Compressed Air system? Contact us! HPA is the ultimate destination for airsoft players looking for the absolute top (lethal silence, instant reactivity, on-the-fly power adjustment). But assembling and calibrating a Polarstar requires great experience! Want a custom HPA rifle? Stop by the workshop! The technicians at M Tactical will guide you in choosing the engine and convert your favorite replica into an unstoppable tournament machine. Write to us in the "Custom Works" section.
The Electronic "Vampire" (Always disconnect it!): FCU control units are always "listening" and consume a very small amount of continuous energy, even when you are not shooting. If you forget this micro-battery connected to the rifle in the bag at the end of Sunday, the following Friday you will find it at zero volts, swollen and ready to be thrown away. Always disconnect the JST connector as soon as the game ends!
