Li-ion airsoft batteries are a great choice for lithium-ready airsoft guns. They are compact, pack a huge amount of power, and unlike Li-Po batteries, don’t have the same risk of over-discharge, making them safer. They also have high energy densities, great capacity and produce more power than other airsoft battery types, like Ni-Cad and NiMH batteries, by far. Improve performance, power, and output: make the upgrade if you can and see why lithium-ion airsoft batteries are taking over.
