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: 9.6v Capacity: 1700mAh Connector: Tamiya Style: Stick Size: 229mm long, 17mm thickLow cost Nimhs are the most affordable type of airsoft battery available for new players with entry level airsoft devices just trying to get started on a budget. Generally Safe Nimhs carry less safety concerns than Lipo with a metal constructed body and less power overall, plus they won't “puff” like a Lipo that off-gases when used improperly. Large Footprint Usually on the bigger side, especially when comparing to similar capacities, Nimh is often twice as large as their lipo and li-ion counterparts. Fewer Charge Cycles Nimhs have fewer charge cycles compared to lipos and li-ions, which in turn likely means that replacements will be needed more frequently. Consider li-ion for the longest life and lipo as a good high performance alternative.
