Matrix High Performance 11.1V Butterfly Type Airsoft Li-Ion Battery (Model: 2000mAh - 15C / Small Tamiya)

"Outstanding batteries. Run them in our Krytac tridents and they last multiple games without needing recharged. Highly recommended!

"Excellent for high rate of fire. Night and day difference between this and an 8.4 (please use a mosfet).

"I put this batter in my Stubby Killer and it works great! Great LIPO battery!

"Is a good battery. Not the easiest to store in a buffer tube though.

"This battery is very good, works in my crane stock and has very powerful cells. I highly recommend it.

"Sweet! Increased the rps of my gun significantly. Lasted through 5 hours of play. Ran out during last round of play but lasted as long as any other battery I have used but increased the effectiveness of my gun.

"The battery works great for the price, fits well in my Matrix SPR15 stock . The battery last the whole day when me and my friends are playing, I would highly recommend it!

"Works as advertised. Stays cool and holds charge.

"I recommend not to get them I’ve gotten multiple batteries in obviously different shapes but none last over 2-3 months so I’m gonna stop buying these bec I always put them in a bag and use a smart chargers ( don’t mix brands or batteries with each other ) but somehow eBay ooff brand is still working till this day so I’ll go with those maybe a little more length but gives any power you want in any certain length

"This battery is amazing! I bought the 11.1v 35C 2500mah battery with deans connectors and I give it 5 stars! I bought 2 of these battery’s and use them in my Krytac CRB that I recently got DSGed. I get about 40 RPS or Rounds Per Second and 377 FPS with .20s. Just make sure not to let it get to hot or it might explode no joke, so don’t go full auto for too long. I usually just switch battery’s in between games to stay safe.

Pros
Lots of mah which is battery capacity
Great discharge rate which is Amps
Fits in a buffer tube nice and snug

Cons
None

"Great batteries! Would definitely consider these If you want a long lasting and powerful battery. I played with 2 of these but only had to use one in a 7 hour game and had checked it's charge and had a little bit less than 1/5 left in it. 10 out of 10.

"Battery works really well and lasts a long time. It is a tight fit into my Krytac CRB, but it does fit. You just have to really yank it to get out. Might suggest sanding the inside of your stock a little bit with a file to make it slide in and out easier. All in all though, great battery for the price.

"Great battery. Lasts me 12 hours of play running a lonex titan A2 motor and M115 spring. Highly recommend.

"I got this for my krytac crb, this is AMAZING!!!!!!!! The rps is 25-28 and almost instant trigger responce. I cant stress how good this is!

"Own 2 of these Fire Fox batteries for both KWA,s they work great ,buy them.
