I own both a KG36C and a M4Tac that are made by KWA and are brand new. I am trying to use a 11.1 1800 MAH Lipo battery and on full auto the gun shoots fine for 4-5 rounds then they start dying out of the barrel. On semi it seems to be o.k. for the most part with a few exceptions(every so often it falls way short). This battery has been checked and it seems to be o.k. and all the guns work fine w/ 11.1 1200Mah lipo(same brand). I believe they are both 25c lipos but the 1800Mah is 45 amp and the 1200Mah is 20 amp? Is this too much power? I haven't blown any fuses and I am wondering what the issue is? What to do with 60$ lipo battery?

Could you clarify what you mean by "dying out of the barrel"? Also, which gun, G36 or M4?

They only go 30-50 feet in G36 M4A1 and two seperate M4Tacs. Might be defective battery. HCA player

Does anyone have any report from using Li-Mn batteries? I hear they're all the power of Li-Po with way more stability. I'm mainly concerned with over-discharging it. I understand you don't want to use more than 80% of the capacity of Li-Po, is that correct? And does that go for Li-Mn as well?

The main thing to be sure of is to not let your lipo pack drop below 3.0 volts per cell. After that, they may not be recoverable. The real issue from a safety standpoint is overcharging. That is when you can have a fire or an explosion. If you treat them right, they will treat you right. I have been using them in my RC truck for over a year, and I love them. Best way to go in my opinion.

Does any one know of a place where i can get a good 11.1v lipo battery & charger for $55 or less? And that the shipping is free because if the shipping isnt free i would just get the lipo from the same place i by the M4a1.

Thanks!

I'm finding a lot of stuff about Li-Mn batteries, and besides available capacities, I can't find any downsides compared to Li-Po. I even saw a video where they punctured it and it DIDN'T burst into an unstoppable fire haha. Is there something I'm missing about them?

Not much.   Four of my guns are now on Li-mn.  It's better in my opinion.  Just more expensive and the public still haven't adapt to it yet.

How about li-mn is metal casing.  I don't have to worry about dropping, puncturing and general accidental damage.

Hey allizard, I was wondering, since you are KWA Staff, if you can tell me what the dimensions would be of the crane stock battery bay in a KM4 RIS. I am trying to track this information down, as I have a guy that makes my batteries for my RC truck, and he is putting together a couple of packs for me for when I get my gun. Being that I am going lipo, it will be a rectangular pack, not a cylinder style pack the li-mn packs are. Basically I need length, width and height if possible. Thank you so much in advance if you can provide this info!!!
