This is an 8.4v 5000mah large type battery. this is a fantastic battery. it has great power and it also last a heck of a long time. i used to use an 8.4v 1800mah in my G&G M14 then i got this and the rate of fire aswell as the range as at least doubled. this is a great battery.
1. Its long lasting
2. Its powerful
3. Its cheap comared to other batteries
4. Its durable
5. Its perfect for Ar's and Machine guns
6. Its dependable
There are really no cons to this battery(at least i haven't found any yet). The only con I could thing of is that its a little to big for some compact submachine guns but thats it.
