Well, it's a battery. But it's a very large capacity, and should last you AT LEAST two day-long battles, without recharing. I say that because I had a 1500 that lasted me all day, and it was a NiCd, so this, being more than double the capacity and NiMH, should last WAY longer. Great for large stocked rifles, it should serve you well and never quit on you.
-Fairly reasonable price
-Should last all day long and then some. Or a lot.
-It's a battery. It does what it's supposed to do, and it'll last you from sunup to sundown to sunup too....you get it.
-The day I received this, my friend found it for 20 dollars less on another site, but I trust Airsoft G.I., so I didn't make a fuss about it
-May be out of some peoples price ranges, and as stated, it can be found cheaper, but it is very much worth the endless stream of fire you will be able to put out with this battery.
