Giant Power 7.4V 300mAh 35C/70C LiPo Battery – JST (BEC)
The Giant Power 7.4V 300mAh 35C/70C LiPo Battery with JST BEC connector is an ultra-compact 7.4v two-cell LiPo battery designed for electronics power supply rather than main AEG motor drive. At 300mAh, the capacity is too small to run a standard AEG motor for a meaningful duration, but it is well-suited to powering low-draw electronics in airsoft builds — including HPA engine FCU (firing control unit) boards, MOSFET units, electronic trigger systems, and other ancillary electronics that require a dedicated small battery supply separate from or in addition to the main drive battery.
The JST BEC connector is the standard small electronics connector widely used for RC and airsoft electronics boards. 35C/70C burst discharge rating provides adequate current for electronics load without the risk of over-current to sensitive control circuits. For HPA players whose FCU or solenoid electronics require a dedicated small battery supply, or AEG players adding MOSFET and electronic trigger units that need their own power source, this 300mAh 7.4v LiPo is the typical electronics supply cell specification.
