I got this battery about 2 years ago and it is amazing. I've not once had it die on me. When I first got it I went out to the woods and shot a 5000 count bag of bbs through my KWA KM16 BR. At the end of the day It didnt seem to lose voltage at all! It fits perfectly into the KWA full stock, with about an inch to spare. The wires take up the rest of the space. My friend got this battery with his JG M16 as well and it didnt even come close to fitting in the stock so now I have 2!
About 20bps with my KWA M16(M130 Spring)
Still works like new after 2 years!
Connectors kinda failed on me after 1 1/2 years of use. (easy fix)
Its probably too big to fit in any other gun
If you have a KWA M16 and you dont wana use a lipo this is your best bet!
or if you have a battery pouch, Get this battery!
