Q: When do I have to charge a LiPo battery?
A: LiPo batteries are highly affected when drained and should not be shot below the recommended minimum voltage. Long story short, if you start with a charged LiPo and use it for a bit and your gun's rate of fire is slowing down and the trigger response getting sluggish, it's time to stop using this one and charge it as soon as possible. LiPos do not like to be drained and once ruined, cannot be restored.

Q: How do I correctly identify LiPo batteries? 
A: LiPo batteries will have two plugs coming out of it as opposed to the one you will find on a traditional NiMh battery. On a LiPo battery, one plug is used to power the airsoft gun and one is for charging. You never want to plug the power plug (the Tamiya plug in this case) into a charger by itself, you risk causing the battery to explode from charging incorrectly. Just about all LiPo chargers are considered smart chargers and most will charge off the smaller charge plug, though some fancy chargers may utilize both plugs for charging and balancing. The voltage of the battery is determined by the number of cells. On batteries where the cells are split up, 2 cells is a 7.4v and 3 cells is an 11.1v. On batteries where the cells are packed together, it won't be so obvious but you can look at the charge plug. One wire will be the negative/ground wire, while the other wires will be connected to each cell, so you can look at those wires to determine the cell count.

Q: Why choose LiPo batteries over conventional NiMh batteries for airsoft guns?

A: LiPo batteries offer higher discharge rates and capacity for their size compared to NiMh batteries, enhancing airsoft gun performance. However, they demand careful handling due to their greater volatility.

Q: How should I care for my LiPo Battery?

A: Proper care includes never completely discharging the battery, stopping its use as soon as the rate of fire drops, charging it before storage, and exclusively using a LiPo charger. Regularly inspect the battery for any signs of damage or swelling.

Q: What are the safety precautions to consider when using the LiPo Battery?

A: Safety measures include using only approved LiPo chargers, avoiding physical damage or exposure to heat, and monitoring the battery during charging. Utilizing a protective charging bag is advised to prevent accidents.

Q: What happens if I misuse the LiPo Battery?

A: Misusing the battery, such as by using an incompatible charger, over-discharging, or exposing it to excessive heat, can lead to damage, potential explosions, or battery failure. Note that the warranty does not cover damage due to misuse or negligence.

About the ASG 7.4v 1300mAh Buffer Tube LiPo Battery

The ASG 7.4v 1300mAh Buffer Tube LiPo Battery stands out in the realm of airsoft accessories as a high-performance power source designed to energize any airsoft gun with precision and efficiency. This Lithium Polymer (LiPo) battery is acclaimed for its superior discharge rates and remarkable capacity relative to its size, especially when compared to traditional NiMh batteries. Its compact design, coupled with high-quality cells and construction, makes it an ideal fit for M4-style airsoft guns with retractable stocks, accommodating the buffer tube with ease. The inclusion of a small Tamiya-style connector ensures compatibility with a wide range of devices, underscoring its versatility.

To ensure the optimal performance and longevity of this battery, users are advised to pair it with a LiPo battery charger, with a preference for smart chargers to prevent overcharging. This precaution is part of a broader suite of care instructions critical for LiPo battery users, given their relative volatility compared to standard batteries. The ASG 7.4v 1300mAh LiPo Battery, with its 15C discharge rate and technical specifications, including a 1300mAh capacity and a 7.4v voltage across 2 cells, is engineered for users who demand reliability and performance in their airsoft engagements.

However, it's essential to note the greater responsibility that comes with the power of LiPo batteries. They require diligent maintenance and adherence to specific usage rules to avoid potential hazards. Misuse or negligence, such as using an incorrect charger, fully discharging the battery, or failing to heed the signs of a low voltage state, can lead to irreparable damage or even cause the battery to explode. As such, while the ASG 7.4v 1300mAh LiPo Battery offers significant advantages for airsoft enthusiasts, it also necessitates a level of care and knowledge beyond what is required for more conventional battery types.
