Matrix High Performance 11.1V Airsoft LiPo Battery Starter Pack w/ BMS Smart Charger (Model: Butterfly Type / 2000mAh - 20C / Deans)

"ownes this bundle for just over a year and nothing has melted so that's a bonus. Batteries work great in a Krytac trident crb and Krytac trident spr (if you need help getting them to fit just put bottom of battery in the removable part of the standard Krytac stock and wedge back in. It's a tight fit and can't close stock all the way). batteries I've noticed recently have started to unbalance themselves but all you have to do is get a .5amp nickel charger untill the battery is back to 11.1v. Then charge with the smart charger in the pack. *do not leave batteries dead for a period of time. They will shorten the battery life of them.*

"Great battery and charger! Battery is easily able to handle 1500-2000 rounds before needing a charge if you take care of it. It also charges fast enough for me to charge it back up between rounds. Small enough to fit into about anywhere, I was able to squeeze this in under a Magpul carbine foregrip.

"This battery is amazing. That's all I need to say.
PROS:
-perfect fit for stock tube
-slight increase in fps
-extreme increase in rof (~20+)
CONS:
-doesn't come with the same charger (not a con, just an observation)
-stock doesn't collapse all the way (not a con personally)
This battery/charger combo is a little spendy but is DEFINITELY worth it!

"great battery have no problems with it so far i put it in my cane stock. i had to file down the inside the crane stock but now it fits perfect and pulls my m120 spring back no problem. it keeps its charge a while. it goes it my matrix SPR.

i recommend this battery to people who know how to use lipo batteries

"This battery is insane! I had to switch to mid cap mags because i couldn't wind the high cap as fast as my gun was shooting. Your rate of fire will be drastically increased with this battey. Plus you can play a ton of games without having to recharge. This battery is worth the price in my opinion. If your ready to step up your game then get this battery.

"All I can say is WOW!!! This battery made my KWA SR10 dump a mid cap in seconds!! This battery is huge, so I am using an external stock battery pouch, and it works and fits perfectly!! This thing is more powerful (more MAH) than my three other batteries COMBINED!! HIGHLY recommended to those who play long periods of time or want to be able to put 50 rounds on target in a second and a half!!

Pros:
High ROF
High MAH
Good for all day events/ops.

Cons: Large - 5 1/8 inch tall X 1 7/8 inch wide

Just a note: This has a large connector so guns with a small plug need an adapter.

"This Battery is awesome! Makes my M4 shoot 30bbs a second. Last all day no problem. Only down side is, I keep burning motors out. Even Shooting Conservatively, the motors tend to over heat and short out.

Because of this I will be down grading to a different battery because I can't find a motor to handle the juice.

But if your set-up is super awesome and for some reason you have a motor I can't purchase, than this battery is for you!

"Great LiPo, amazing rate of fire. Bumped my 22 RPS gun to 28 RPS, great for pulling high FPS springs or for just a high rate of fire set up. Great discharge rate of 40C makes for a ridiculously fast set up. I wouldn't recommended this for anyone using a low reinforcement gun or piston, as you would run a high risk of stripping the piston.

"I have had this battery pack for about a year and a half, play on average twice a month, and have only recharged it twice...that being said, I do shoot very conservatively but that is still a heck of a long time to hold a charge. On the days I play, it's either pulling the M130 spring in my primary, the M120 in my secondary, or either of the M150's in my DMR's. General trigger response and ROF (especially with the M120 spring) are completely insane! Many of the guys and gals on my team (sogairsoft.org) use the same battery and have had similar good results. Great buy, just make sure your gearbox and wiring can take the extra power...if so, you'll never use another battery again (except for those below-freezing winter days when a lower voltage battery can save your gearbox from cracking). So good that I'm buying another one soon!

"These battery packs are awesome! The rate of fire clocked faster than my Venom and it lasts almost 3 times as long! I have used many lipo and I have never used on this powerful. There are some 7000mah I am thinking about trying but they are simply too big, these are just the right size.

"So far, Evike is the only store I can find a LiPoly battery package for this price. Despite my worries of stripping out my gearbox, I've been running my CA CQBr with this LiPoly for about 6 months now without any internal problems.

I recommend upgrading at least the piston and spring, as the LiPoly will wear both out much faster than the average Nimh or Nicad battery.

"i absolutely love this battery. it works so well with my gun and incresed the bb's per second by about 10 and incresed the fps by a considerable amount. this battery works fantastic and i think the price is acceptable considering how much it helps ur gun become better. i definetly recommend this but remember that some guns are not li-poly ready and need the neccesary upgrades.

"amazing battery

easily THE BEST 80 BUCKS U CAN PUT INTO AN AIRSOFT GUN i wouldnt reccomend using this battery fr cheap guns without good internals cuz the high rate of fire could strip the piston or motor

"wow.. just wow. this takes my ca scar to a whole new level it fits in the stock and works like a pro. even with 400 fps it still fires faster than any battery ive used. a must have for any ca scar.

"I cant get my charger to work so i haven't put it in my gun. I can imagine would it would be like when it is fully charged. I got a m4 with a systema turbo motor 8mm ball bearings reinforced gearbox m85 spring high speed gears and this thing I am just a little disappointed that it wont charge. I race rc cars so I know a lot about batteries. First of all lipos are chemically unstable so they are really tuchy. Never completely discharge them, don't even let them get low. If they do get low they get hot and blow up. Don't over charge them or they will blow up. Don't let them get hot or they will blow up. Don't short them out or they will blow up. Always store them charged so that they have a longer life. If you follow those rules you should be fine. Only gave 4 stars because it won't charge. Another thing if they do explode you can't stop them so just set your gun down and get everyone away and watch a very expensive fireworks show.
