Keenstone 9.6V 1600mAh Butterfly Nunchuck Stick Mini Battery Pack with Mini Tamiya Connector for Airsoft Guns ICS CA TM SRC JG G36 G&M733: Compact and Powerful Battery Solution Review

The battery worked well in airsoft guns with little use. However, after 6 months my son's gun became very hoarse and a hissing sound came out. Pulled the battery and it was very hot and there was an overclocking response. They put him on a concrete slab and let him calm down. The battery is outside the return window so I'm stuck. Wouldn't buy again and put the other one we bought out of use.

I had no problems with the batteries. I bought 3. All are charged/discharged normally. I recommend using a smart charger, fully discharging before recharging and fully charging before reusing. I don't know if these batteries have "memory" or not, still a good habit for batteries. I know overload will ruin them. In any case, the batteries I received are quality batteries and work as they should. I will buy at least 1 more.

Bought for my son's Lancer Tactical AEG SR-16 electr. automatic airsoft rifle. WOW, what a difference when shooting in auto mode. Previously, you could see about 7 inches of space between each bullet as it exited the end of the barrel. There is now about 1 inch of space between each bullet that comes out of the barrel. It's a constant stream of BB when it hits the target. And the wires are twice as thick as the other battery, which increases the discharge rate. My son is very happy with this…

Playing Airsoft since 2003. There are 8 AEGs and 9 GBBs in my personal collection. Since then I have been setting up and repairing AEG. There will be those who will say that a battery is a battery. All batteries are sold with two ratings - rated output voltage and capacity, usually in milliamps (mAh). Other things being equal, they will all do what batteries are designed to do. While this is true in terms of delivering power, there is a difference in the amount of "boost" a battery can provide.
