Matrix High Output Nunchuck Type Airsoft NiMH Battery (Configuration: 9.6V / 5000mAh / Standard Deans)

"These work great in out M4 guns that we use.

"I love these batteries, I have bought two of these now and the only problem I've had is due to my less than quality crane stock which almost ruined an expensive butterfly battery. I would recommend to anyone looking for good battery.

"An amazing battery that has lasted me years at this point, and is an amazing and cheap upgrade for any beginner airsofter.

"The MATRIX HIGH OUTPUT BUTTERFLY TYPE AIRSOFT NIMH BATTERY (CONFIGURATION: 9.6V / 1600MAH / SMALL TAMIYA) is a long lasting battery that works great in my AEG rifle.

"got the 12v 1600mah and its give quite a good output.

"10/10 battery!!!!
Insane life span lasted me 5 days before it died
Extremely quick charge time (2 hours) fully charged
Works really well

"I bought the 9.6v butterfly-type 2200 mAh (small tamiya) battery, and it is probably about 20% bigger around than a 1600 mAh 9.6v battery, for reference. If your battery compartment is a tight fit for that, it won't fit the larger capcacity. However, that said, The battery obviously will last longer.

2200 mAh Version:
Pros -
* Good quality
* Long life

Cons -
* May not fit the battery compartments on the tighter end

"These batteries lasted me an entire 9 hours full charge, I would strongly think it would last 12 hours until it's drained. I plan on getting a new one for my rifle, I highly recommend this rifle.

"I bought these batteries for my Cyma M4 Keymod since my Lancer Tactical 9.6V don't last as I thought they would, I decided to buy these as my primary batteries and they are really good. Rate of Fire is consistent from what I seen (yet to Chrono), trigger response is good and they last for a very long time, like maybe around 8-9 hours maybe. I highly recommend these!

"Great battery! Perfect fit in my AK stock and lasts for hours! I bought a second one for the Milsim event I was going to (Red Rising 2) and never had to even swap out for the second battery. Give this thing 2 hours of charge the night before a game and it'll last you all day!

"barely fits in my A&K sr25. if you were wondering, yes it will fit in the sr25 with the full stock, this battery is massive and well worth the money. id recomend using a smart charger for this tank

"Battery is worth the money, it works amazingly, and I have had no problems with it so far.

"Great for airsoft rifles with a crane stock.

Holds enough of a charge to get through an entire day of game play, with juice to spare.

"These Batteries are wonderful i have one for my A&K Masada and one for my Umerex mp5 and they have long battery lives and great rates of fire.

I would highly recommend these batteries
