Matrix High Output Large Type Airsoft NiMH Battery (Configuration: 9.6V / 4000mAh / Large Tamiya)

"this battery barely fits in the stock of my mp5. i had to mod the stock so that the battery could fit. this performs very well and easily pulls the m120 spring with a good rof. you should get a good fuse tho because it will blow the stock ones

"I bought 3 of these monsters and they are way worth every penny!You will have to take a wood chisel and knock out the supports inside the stock to fit it in but it's easy enough to do. I've put them into a Cybergun Thompson (whoa 10 times better), a JG SoCom M14 and a JG MP5 RAS model and it made good guns into GREAT guns with this minor mod.Be warned it adds weight too and will totally fill a full sized stock. This would be excellent for a SAW ond a battery bag.

"I bought this last year or so and I can say is WOW it fits like a glove in my kwa m16 and the rate of fire was like a hand of god slapping my enemies ( ok it wasn't like that) but I still got a good 20 rps and the response time was almost instant. it will last all day and if it does die you either didn't fully charge it or your using WAY to much ammo.

pros
rps
response time
output
4000 mah

cons
my not fit in smaller stocks since the kwa stock bigger on the inside.

"This battery last you all day...stay trigger trigger very happy long time!!!!

PS....thanks to this dang battery I buy rice bags of ammo...

Thank god airsoft ammo is so cheap!!!!

PSS BRING THE RAIN!!

"Great battery. The capacity of the battery means that it can last more than a day's worth of shooting. The only problem is that it is very large. Other than that, it's a great product.

"This is a very good battery especially if you dont want to run lipos through your gun. I put this battery in a battery pouch on my G36c handguard and it suprisingly doesnt look too bad. I run a m120 spring with a matrix magnum motor and this batery gives me around 28 RPS!!! I would say if you have room for the nearly 8X2 inch battery, then definitely use it.

Pros:
-Great battery that lasts a long time
-Gives your gun high rps without useing a lipo

Cons:
-Very large about 8 inches long and 2 inches wide
-Can make your gun front heavy if you put the battery towards the front

Otherwise the large sise this battery is beast!!

"i have this battery and it is just amazing i use it in my m16 and its to good, its worth the money

"Not much to say... Even though it's an 8.4, it gets a better ROF than some 9.6 batteries I've seen.

Pros:
Gives good ROF
Lasts a good minute. Never died in a game, and I've camped overnight!
Durable

Cons:
Uhhh... Tamiya? Well many people use that, so that can't really be a con...

Just make sure you use a good smart charger, and your set to play all day!

"This battery is fantastic!

I have had this battery for a year now, and it has never failed me. it also outputs more energy than a standard 9.6 which means significantly higher rof than a 1600 mah 9.6. The battery is fairly large, but will fit in over sized stocks such as m16 full stock, m249 saw etc... It is a great battery to own, also because its 5000 mah, it lasts an extremely long time. i use it on my rpk and saw and it goes through approx 3-4 box/drum mags

all in all, if you are looking for something to rely on, this battery is for you!

"WOW! Prepare to bring the pain lol! Haven't had a chance to test the rof yet, but this baby makes the gun sing sweet, sweet melodies of bb filled goodness. Yeah I know, I need to stop further attempts at poetry.

Things to know
-BIG BATTERY! If it goes in the stock of your gun, you might have problems. Mine has the wiring in the front and I just needed to get the external battery pouch. No biggie for those of you with a similar setup. I think its safe to say it won't fit in a peq box. Not the ones I've seen anyway.
-Its kinda heavy, but thats to be expected. My M4 is now very much front heavy lol. Oh well, I'd say the benefits outweigh this little concern.

All in all, its a little pricey (to me anyway), but its well worth it. Watch your opponents' eyes get really big when they see anything in action with this hooked up to it!

"This thing is a freaking monster! Make sure you get a bag that's big enough for it, or that your gun has enough for it to fit, otherwise you'll have to Redneck it to your gun. For those who don't know what that means, let's just say that it involves duct tape.

"Got this battery today for my kwa sr12 and it works great. This battery puts out so much more power than intellect batteries and this one last ages. Perfect for a gun with a big stock like mine. Couldn't be happier

"This battery is simply amazing!! The high voltage gave my CA M15A4 Rifle a SCARY ROF. The mAh is almost ridiculous! I didn't need to charge it for 1 month and thats with a large skirmish and a couple target practices. Do not be fooled by the looks at all!! this is a force to be reckoned with!

Pros
-Huge capacity
-9.6 Volts!
-Durable wiring

Cons
-EXTREMELY LARGE! unless you have an external battery pouch or a large stock to accommodate for the battery, it might be cumbersome to some users.

"Bought it. Shipped a couple of days after. Took a day to ship. That was pretty sweet. This thing fits M16 stocks perfectly. I have KWA M16A2 DMR (evike custom) and it's amazing. It's kinda heavy though, which was good for me because my gun used to be so front heavy. Now it's a little bit heavier but a lot more balanced. Five starts. Absolutely beautiful battery here.

"Great Battery! A good alternative to the lipoly because its safer / more stable power. (NiMh)
The drawback is you need to have place to put it. Its a bit larger than a large type 9.6V.

However, perfect for a P90 with box mag! = )

Last almost forever and because its NiMh it does not require discharging. With a smart charger, you will never ever run out of power. (How do you go thru 10.8V of 4500mah in a day of playing....its almost 8000 rounds even on a M120 spring).
