11.1v Lipo "Run Time"?

[Chachi]

I have an 11.1v 1600mah RA-Tech lipo pack coming, and I was curious if anyone had any experience with what an estimated "run time" I would be able to get off this pack. I will be using it in a KWA KM4 RIS, firing .25 bbs. Would I be able to get through a days game with this, if I am not doing the spray n' pray method through the day?

im not 100% sure on the lipo, but i believe the capacities are similar to most nimh batteries. 1600mah should easily last you all day unless you just play with your trigger down.

if im wrong, im sure nec will correct me. he seems to be "that lipo guy".

From what I have heard from lipo users and seen for myself, it seems like a Lipo will last longer than a similarly numbered NiMH. So an 1100Mah Lipo runs as long as a 1600-1700Mah NiMH.

anywhere from 1200 to 1400 bbs

Some say it is 3x as long as standard batteries, and I know people that have used entire M249 box mags on a small 1100mah lipo before, but I'm still not 100% sure on exactly how much more capacity they have. I've never even had a ROF drop using my 4000mah lipo and I shoot a LOT.

I emptied half a 2500 round box mag with a RA Tech 11.1V 1600 mah that i have

lipos discharge evenly without any falloff, so you wouldn't notice a rate of fire decrease when the battery was discharging. the way i understand it is it will just stop when it's out of juice.

[Chachi]

Well, I am versed in Lipos as I run some fatties (2 x 8000mah) in my rc truck. But for airsoft, I have no clue how their capacities relate. That is where you all come in! Thanks for the info so far everyone, I really appreciate it. I think I would be good with the 12-1400 rd range. For now, I will be starting with one battery (other than the free 400 w/ my AEG purchase), and I wanted to see if I can make it through Conflict Europe on the one 11.1v 1600mah pack.

[Beran]

i'd bring extras just in case, but you should be good on just the lipo. the capacity thing varies pretty widely depending on the gun. some motors hog more juice, some wires don't move it as efficiently, and some shim jobs make the motor work harder or easier. the same battery may last 2000 shots in one gun and only 1000 in another. your mileage may vary, and you wont know for sure until you try it. hence the backup. i bring like eight batteries and three or four guns to every game i go to so ill always have something that works.

My experience is that the MAH rating is effectively doubled, so a 2000mah lipo would equate to a 4000mah battery.
Also, an 11.1v battery will equate to a 12 volt or higher output so make sure you have a delay cam on your sector gear or you will have alot of dry fires as the tappet plate cant keep up without it unless very small, short bursts are used.

I have 2, 4000mah 15C batteries for my AK and I used to go all day playing with a bb slinging RPK and I havent been able to get it to chug - it's run strong all day.
Another player here has an 11.1v lipo and his gun sounds like a minigun on crack. One caveat of this however, is he keeps blowing through pistons..

[Chachi]

Yes, very good plan to have extras on hand. That will come down the road for sure, but for now, after pretty much getting my whole loadout and AEG in the last month, I am going to have to run with one at CE. My AEG is un-moded and brand new. I'll have some time to run plenty of BBs through it before the 17th, so hopefully I'll get a good idea of run time by then. Thanks again!

No, they have ROF drops. Lipo users use that ROF drop to know when to stop using their battery so that they don't get over-discharged. A sector gear cam isn't completely necessary, my SCAR doesn't have one and feeds fine with STAR pmags which aren't very good mags. It's running a Systema magnum motor and a pretty light piston/weak spring too.

A 1600mah lipo should last you quite a long time, but I would always bring an extra just in case. At the Civil war event I took along a 8.4v 1200 mah and that lasted me the entire game. Around a 1000 rounds, so a 1600 mah lipo should last a bit more then 2500


Like beran said, you would pretty much have to play with your trigger taped down to need more than one lipo for the game.

I get around 4 shots per milliamp. I can generally run two 2500 round box mags through my SAW with an 1100 milliamp pack.

Like League 4 said, it's been "said" that Lipos get 3 times as many shots per mAh than their NiMh counter part. although the exact time the battery will last will depends on many factors: strength of the main spring, how well the gears are shimmed, how efficient the motor is, type, size and material used in electrical wiring, discharge rate of said Lipo continuous (under load) and instantaneous (start up) and many more factors.

I have a 7.4v 1800 25c lipo that seems to last me about all day and I shoot around 2-3000 rounds a day, depending on what types of games we are playing.
I say depending on how much you shoot in a day, I would buy another battery if you plan on doing an overnighter or "long" day game.
