Matrix High Performance 11.1V PEQ Type Airsoft LiPo Battery (Model: 1500mAh - 20C / Small Tamiya)

"Works great in my M249. Perfect fit.

"I use this with my Krytac Trident MKII PDW-M Airsoft AEG Rifle and I have no issues. The battery last all day for game play and doesn't take long to charge. It fits well in the PDW stock with the short wire, I would recommend this battery if you don't have a lot of space in the battery compartment.

"I use this in my Krytac Trident MKII PDW-M Airsoft AEG Rifle with no issues. The longer cables make a little trickier to fit in the PDW stock but still fits. Charges in about 30-50 minutes, depending on the usage. The battery last all day w/ no problem.

"Decent batteries, I prefer Elite Force batteries myself but if Elite Force doesn't have the size I need these are my next choice and if Umbrella Armory uses them they gotta be good right

"THE BEST BATTERY FOR THE MONEY! IF YOU ARE EVEN CONSIDERING GETTING THIS, THINK NO MORE AND JUST BUY IT!

It fits perfectly in the the PEQ-15 box! Snug but not tight. Doesn't wiggle around but not impossible to get out either.

The battery life is PHENOMENAL! I run mine with a VFC H &K 416C. For those of you who know nothing about this gun. It shoots hard and it shoots FAAASSSTTT. I also have a very fast trigger finger and I run it hard all day long. It lasts on average 5hrs which is damn good.

Long story short, just buy it!!!

"Works perfect for my Amoeba AM-013, the battery compartment does not fit many sizes of battery but this actually fits w/ a little wiggle room. I have 5 of these and have never had one die, I typically run 2,5000 rounds before I swap the batteries out. I run this in conjunction with a Lonex A2 motor. Bottom line, these work great with a reliable discharge, fit just about any configuration of battery compartment, and charge quick.

"Got this for the Ares Amoeba am-013 and it fits perfectly! The battery lasted me a whole day on the field.

"Received this with my Evike.com order today. Fits in the PEQ-15 perfectly and the ROF is 26bps in a KWA KM4 with an M130.

Hasn't even died yet, after over 4,000rnds it hasn't changed. Still a solid white stream of bbs.


And in response to the guy before me, it says right in the description "for PEQ-15 Type Battery Box". So no, it's not going to fit in a handguard. It's made for a PEQ-15. Fits it perfectly.

"GOOD FOR THE PRICE

Pros:
-Cheap
-Extensive variety
-Works pretty well

Cons:
-A bit more disposable, they can die for no reason
-If you don't use a good charger, they can unbalance

"I'm not going to lie, these things are monsters. I didn't realize it, but it fried my trigger contacts in my ERG, and ravaged my wiring harness. I don't recommend this for anything other than LMG's don't make my mistake and fry your guns. Other than that, trigger response is awesome with them.

"Seems like a good 11.1 with large capacity and such, but it is advertised as a "PEQ" box battery and will not fit in either of mine(PEQ 15 and PEQ 2 style). Overall seems like a good battery but WILL NOT fit in a PEQ box.

"This battery is awesome. The trigger response is a lot better than what it was with my 9.6 and it made my gun shoot a lot faster. only thing that was a con for me was that it didnt fit in my handguard like i thought it would but its all good im just gonna buy a peq 15.

Pros:
nice trigger response
made my gun shoot faster

Cons:
Didn't fit in my handguard..

"This battery blows up
It is a good battery don't get me wrong but if it inflates with something and your dumbass brother stabs it to release the pressure it will light on fire in a class charlie fire and if you don't have some PKP lining around then don't stab it.
pros
good battery
fits in peq
works great
holds a charge

cons
not good protection from knives

"This battery will not fit in a PEQ-16 battery box despite it being advertised to be able to do. These batteries are just a hair (~0.5mm-1mm) too thick to fit in a PEQ-16 battery box like this one: http://www.evike.com/products/32273/

I purchased two of these hoping they'd fit after I verified based on the given measurements that they would. However the measurements on the site are under-reported. In reality this battery is between 0.69mm-1.08mm thicker than described. It is also wider and longer than reported on the site.

The actual measurements of this battery are: 76.21mm-78.10mm* x 35.37mm-35.45mm x 20.69mm-21.08mm

The reason I provided ranges was because between the two batteries I received both were larger than the reported measurements and between the two of them they varied in size.

*Included bent wiring in length measurement since the extra length makes a big difference in their ability to fit in battery boxes.

I've successfully been able to use Echo1 XCR 11.1v batteries in a PEQ-16 battery box: http://www.evike.com/products/41588/
They clearly have better quality control as those batteries have much smaller variances in size.
