The ASG 7.4 V 1300 mAh 15C LiPo stick battery is a compact lithium-polymer battery pack designed primarily for airsoft AEGs and similar hobby applications where space inside the rear stock is limited. 
 
Key Features & Benefits:
Voltage & Capacity: 7.4 V nominal voltage with 1300 mAh capacity, providing a balance of runtime and compact size.
Discharge Rate: 15C continuous discharge rate — capable of supplying steady current to maintain consistent performance during operation.
Stick Format: Slim single-block stick form factor that fits into most standard stock tubes on AEGs and other airsoft replicas.
Connector: Typically fits with a Mini/Small Tamiya connector and includes a balance lead, allowing for safer and more accurate charging.
 
Important Usage Notes:
ALWAYS use a LiPo-specific charger with balancing capability; standard NiMH/NiCd chargers can damage the battery or cause safety issues.
Avoid deep discharge — fully draining a LiPo battery can seriously reduce life or permanently damage it.
Proper storage (at around ~3.80 V per cell) and moderate temperatures help prolong battery life.
Because LiPo cells are sensitive, they should never be punctured, short-circuited, or physically damaged.
