LiPo Technology Overview

Lithium Polymer (LiPo) batteries are the preferred power source for modern airsoft electronics due to their high discharge rates and compact form factor. Compared to older battery types, LiPos deliver more power for their size and weight, allowing them to fit into tight builds without sacrificing performance.

Benefits of LiPo Batteries:

• Lightest rechargeable battery type for its capacity

• Very high discharge rates for rapid power demand

• Low self-discharge during storage

• Faster charging compared to older chemistries

Recommended Applications

• HPA FCUs (PolarStar, Wolverine, etc.)

• Electronic trigger units

• Compact airsoft builds with limited battery space

• Low-drain electronic airsoft accessories

Package Includes

• NUPROL LiPo Battery 300mAh 7.4V 35C (JST)

LiPo Safe Use Warning ⚠️

Lithium Polymer batteries must be handled with care. Improper use, charging, or storage can result in swelling, overheating, fire, or explosion.

Always follow these safety rules:

• Use a LiPo Balance Charger ONLY

• Ensure balance lead is connected when charging

• Always use a fire-retardant LiPo charging bag

• Never leave batteries charging unattended

• Minimum cell voltage: 3.3V

• Maximum cell voltage: 4.2V

• Maximum charging rate: 3C

• Stop using immediately if battery swells or exceeds 70°C

Failure to follow these instructions may result in serious injury or property damage.
