Li-Poly Battery 7.4V for HPA FCU Units by ASG

Power up your HPA FCU unit with a Li-Poly battery from the Danish brand ASG. This battery combines lightweight construction and compact dimensions with high performance, making it the perfect power source for all HPA weapons with an electronic control unit. Li-Poly technology offers better energy efficiency and higher power compared to traditional NiMH batteries. It is also significantly smaller than Li-Ion batteries, making it easier to fit into your weapon without needing external battery pouches or imitation PEQ boxes, thus maintaining a realistic weapon appearance—a must for every Mil-Sim operator and Reenactor.
The battery features a JST connector and a balancing connector for safe and efficient charging. Theoretically, it can also be used to power AEP pistols and electric drum magazines designed for the same battery voltage and equipped with a JST connector.

  • Suitable for: Polarstar F1 / F2, Wolverine Inferno, GATE Pulsar, etc.
  • Dimensions: 38 x 15 x 20 mm
  • Voltage: 7.4V

Maintenance and Charging Instructions

For optimal performance and safety, follow these battery maintenance guidelines:

  • Before first use, fully charge at a lower charging current (0.1-0.5 A).
  • Avoid overloading and complete discharge of the battery.
  • Store the battery in a dry and cool place at approximately 75% capacity.
  • Charge only with a suitable Li-Poly charger and preferably in a protective bag.
  • Never charge the battery unattended.
