This is the most common airsoft battery out there. This is normally recommended with MOST airsoft guns. Will fit most m4's, G36's, m16's, AK's (wired to the back), MP5's, P90's, AUG's and more. We HIGHLY recommend that you use this in CONJUNCTION with a smart charger or else a normal charger may burn out your battery. On occasion, if the EXACT manufacturer battery is unavailable, we will substitute the battery with the same style, same mah, same voltage, and same quality but a different manufacturer battery.
All batteries should only be charged in an area away from flammable objects due to risks in charging batteries.
