No Puff. These batteries will never puff and become unsafe, like lipos will that have been either neglected or simply aged over time.
No Memory. These batteries can be charged from empty or nearly full without damaging the battery. Even if your battery gets low and your device cannot cycle, the battery is still within safe operating ranges and can be charged safely back to 100%.
More Capacity. The batteries can store on average 2-5 times the energy of other airsoft batteries, keeping you in the game longer.
No Fade / Lasts Forever. They can hold a charge for months and still be ready to use on game day. An extreme example is a pack used for testing, charged in 2012, which still holds 88% of its life in 2018. These packs can also be charged over 300 times and still store 80% of its original capacity.
