i currently have a crappy 8.4v standard battery for my src g36c
im building a remote battery unit to go in a spare pouch and have a curly wire from vest to gun . im thinking of using a bank of lipo battery's although
simple i am wondering if i could use RC lipo battery's because of there lower price?

No matter what the intended use it's all about volts and amps, do the math and you should be fine :)

I have a M249 Squad Assault Weapon (SAW) and I hooked up 16 batteries in my Backpack on a voltage regulator so I can control ROF when needed. Its 25,600 mAH.
Peace through superior firepower.

@Rezonate, are you comfortable with your electronics? You have to be really careful playing with your voltage. Its really easy to put too much through the motor and cook your gun. Those M249's are expensive!

I would suggest using one big battery (or whatever you need) and somehow add it to your weapon. You never know when you'll need to drop the gun or move it in some weird angle/fashion.

If using batteries that can supply very high currents, place a proper size fuse in the battery pack. A shorted out connector with no way to shut it off is no fun when the cord becomes a smoke bomb and then starts to set everything it touches on fire.

Safety first on high current batteries.

Thanks for all the replays im using 11.1v lipo 2200mah two to start with i will see how long they last in my g36 shooting at atleat 300fps and at a reasonable rof is there any point in using deens connectors?

Deans are a recommended upgrade. Hope your lipo is at least 20c or better. 2200 mah should last you for an all day event. If your going to use a 11.1v, have you gone thur your gearbox and done all the tweaks? Also a mosfet is recommended to prevent trigger contacts from burning out. You may want to stay with a 7.4v to start off.

what internals do i need?
im using lipo because i don't like nickle metal hydride battery's and there over priced. i found two lipos for the price of one standard battery with half the capacity.
in my src g36 gen2 I have a v3 gearbox with full metal (high torque so they say) gears.
would these internals last till i get my license i think its like 3 games in a period of 2-3 months?
you said use 7.4v wouldn't that have slightly lower rof than standard battery?

The 7.4 4000 mah seems ok. Check out Hobbyking.com, I buy my lipo there, also noticed they are a sponsor of this forum. As for internals, stock stuff is fine. Recommend you do some reading on airsoftforum.com. Shim, correct AOE, seal air leaks.

i just had a cool idea where for normal rof is acceptable i use 7.4v and then in short cqb situations bump it up to 11.1.
i have found a good deal on 11.1 lipos on ebay 2 2200mah 20c 3s packs for £21.99
how many cells do you recommend 2/3
what is the minimum c rating recurred for airsoft guns?
should i buy several 1000mah or buy 2 2200mah?
