Lipo batteries, HELP

[yemenfool]

Ok so ive been into airsoft for a couple years now, just bought an M14 and I am curious about lipo batteries. I know the previous owner of the gun used a Mystery brand 2400 mah 15C lipo and he said it worked very well for him. I know pretty much nothing about these batteries and was wondering what you guys would reccomend I buy in terms of a battery, charger and whatever else I need/need to know to safely use lipo batteries.

Thanks for your help

M14?

Buy an 8.4V 3600+MAH Large battery.

In something that has as much battery space as an M14, I wouldn't even bother with LIPO.

But if you REALLY want to use LiPo, you can fit a 4900mAh 11.1v 25C in this rifle. Rhino is a very good brand and quite cheap.

Heh, I use that 11.v1 4900mah Rhino in my 249
The only reason you'd need a LiPo in an M14 is to get your shots off faster. It's a viable option, but keep in mind you need room for the LiPo, AND it's protective equipment.
IE the 11.1v 4900mah LiPo Kos is talking about is the exact same size as a 9.6v 4200mah NiMH battery. So you'll need to find one that fits your stock, which is easy.
Then you need to make room for a PCB (they're tiny, like the size of a nickel), and if your running 11.1v, you may want a triggermaster to reduce your ROF so your not getting those shots off TOO fast.

Anyway read this first if you want to get into LiPo stuff:

Sorry my HDD committed suicide and I lost all my data, including that 3 page article on LiPo's that was a really good read...

Anyway it's not something you can just buy and slap in your gun like a NiMH battery, you have to know the dangers and what can happen if you aren't aware of what's possible.
I've only heard of one LiPo getting toasted in airsoft, and it was due to gunsmith error. But he saw it smoke, and had time to get it out the door and throw it in his backyard before it did any damage. Even then I don't think it burst into flames lol

Do you mean a fuse or?...

I think he was talking about the lipo cut off switch, so that the battery doesn't discharge to an unsafe voltage

Yea it already has a triggermaster installed. So what about a charger/discharger and can you tell me more about a PCB?

I use the iMax B6 charger to great effect.
A fuse is one thing, a triggermaster is another, a MOSFET switch is another, and a PCB is something else as well.
A trigger master is a fuse and MOSFET switch, but it is most definitely NOT a PCB (protection circuit board).

The new triggermasters are designed to measure input voltage, and they'll cut off once your LiPo reaches it's minimum voltage (6.0v for a 2 cell, 9.0v for a 3 cell).
IT DOES NOT MEASURE VOLTS PER CELL
An 11.1v LiPo, at 9.0v, is empty. However that could means that there are 2 cells at 3.1v and one cell at 2.8v, which would mean one cell is damaged.
What a PCB does is measures the voltage of each individual cell, and cut power if ANY cell reaches 3.0v

It's also compatible with a triggermaster (plugs into the side), and compatible with a MOSFET switch (solders into the switch)

A PCB is a really important safety measure for any LiPo user, especially if your running 11.1v
