The only airsoft battery made in the USA with a one year warranty. Titan Power packs have the performance, high capacity, and reliability needed to make your battery a part of your kit- not a consumable. Voltage: 7.4v Capacity: 1200mAh Connector: Tamiya Style: Stick C Rating: 25C Size: 127mm long, 20mm wide, 10mm thick Superior Trigger Response With the best discharge rate for airsoft, this means that Lipos have a very snappy trigger with a hard to beat trigger response. Higher Compatibility Made in many sizes and shapes, Lipos can not only fit in most airsoft devices, they also have a much higher chance of fitting in the less common devices. Safety, Maintenance, and Longevity Considerations Lipos can be over discharged (used to failure), have a high puncture risk (which causes fire) as the plastic construction isn't as strong, and will generally have both less usable storage and less total life that li-ion.
