Matrix High Performance 11.1V Brick Type Airsoft LiPo Battery (Model: 1800mAh - 20C / Small Tamiya)

"So let me start off by saying that this battery is incredible, I bought the biggest of them all (65C 5000mAh). I use it in my DSG and it lasts forever, like a full day and a half of play forever, it's honestly crazy, it gives me incredible trigger response and has boosted my rate of fire tremendously. So I have nothing but praise for the battery itself, that said, it is GIGANTIC. I would be baffled if anyone knew a gun that could fit the battery so keep that in mind. My solution was to buy a buttstock mag pouch, I ended up choosing one from Condor ("Condor Tactical Butt Stock Mag Pouch" on Amazon) that fits the full style stock on my DSG and it fits perfectly. So all in all, incredible battery (IF YOUR INTERNALS CAN HANDLE IT, you will definitely need upgrades), but keep in mind you will likely need some form of external storage or mounting.

"Got these for my AUG, fits perfectly. These are compact and last long.

"Got this lipo for my arp9. Fits nice in the buffer tube and will have enough room to collapse the stock completely. I also got the 1000 version but it shipped 1100. I do not know why but I am not complaining.

"Fits into my G&G buffer tube as described. Snug fit.

"Great battery! But its listed as a 1000 mah but i got a 1100 mah. Im not complaining its just interesting.

"Works well and is very compact. I have no complaints.

"It works and it charges. It's a win for me. Nice and compact too

"Fantastic battery! I have had no problems. Lipo's are really really good.

"No problems until I accidentally charged it as a NiMh battery. Oops. Poofed up but didn't burn or explode, so that's a positive sign to its quality, I suppose.

Otherwise, this is one of the very few LiPo batteries that will fit into oddball battery compartments. For example, I have a P-90 Terminator and a modified JG AUG and it's the largest battery that'll fit. Battery can also handle the M140 spring in the modified AUG.

"This is an amazing battery. If you have the battery space and the right gun. You can totally kick ass with those battery, I can't recommend it enough!

Pro:
-long lasting
-increase in performance
Con:
-you don't have it :p

"I got this battery as a package with my AUG A3.

Performance is great. I get comments about the fire rate of my rifle being really fast on a stock internals. It lasts the whole day with heavy use.

It charges to 12.4v (that is normal and not unusual for 11.1v lipo) and after a full day at the field and 2000 BB's it still reads a voltage of 11.3.

It fits very well with plenty of room to spare, even with a MOSFET it fits well.

They warn you about not discharging below 3V per cell but do not mention storing them charged. You are not supposed to store lipo at about 3.8 per cell and check them monthly to make sure they do not discharge below 3v per cell. Read up on LIPO health in detail its important for the batteries health. So choose a charger with storage mode. The generic chargers that come with the kits are great for charging but not storage and maintenance of batteries.

"I have 2 of these. Using 1 in a wickedly quick semi-auto sniper rifle. Lasts 2 days (6 hours +/ day) in full on rage mode. The other is for an M4, also lasting all day with frequent full auto. Excellent batteries for the price, no cell failz w/ mosfet protection. Had them for just under a year.

"Great Battery, and I've noticed quite an overall improvement in my ROF/Longevity/Trigger Response with my JG G36(K)(dmr version). This battery has been very good to me so far, and I hope it stays that way! LiPo is the way to go.

Upgrading the Wiring/Fuses/TriggerContact/Deans soon...

"I was wondering if this lipo would fit into the buffer tube of a combat machine. I want to put on a magul stock, so a small lipo is preferable.
