About the Echo1 LIPO 4 - 11.1 1300mAh PEQ box battery

LiPo or Lithium Polymer batteries are high performance batteries you can use to wake up any airsoft gun. They possess higher discharge rates and higher capacity (mAh/milliamp hours) for their size compared to conventional NiMh batteries. With great power comes great responsibility though. We do not recommend LiPo batteries for players just starting out as they require greater care and responsibility to use as they are more volatile than your standard batteries. The rules to using a LiPo battery are: 1) use the correct corresponding LiPo chargers - using a NiMh or incorrect charger settings will ruin a LiPo battery and cause them to explode. 2) Never drain or fully discharge a LiPo battery - the moment your gun starts shooting slower is your signal to charge the battery. Continuing to use the battery while it's at a low voltage state will take it beyond the point of no return when it comes to charging it. 3) We do not cover batteries under warranty due to misuse or negligence.

This square shaped battery is designed to fit PEQ style battery boxes or full stock guns.

Honestly, this is the only airsoft shop I will ever buy from. Their guns are always quality. Their custom work is mind blowing. Their staff is not only helpful, but always happy to help. If you are just starting out or have been playing for years, these guys have guns, gear, and good advice for every situation.

Awesome company and products. Received sooner than projected from Colorado and I'm in California. Less than 2 days from placing order to receiving it. . Everything shipped as ordered . Incredible selection and great price... Did my homework and eventually came back to them. I'm glad I did. My squad will be ordering and I be ordering more gear as well.
