MOSFET?

I was wanting to use an 11.1v lipo battery with my AEG, but everyone says you need a MOSFET to do it. What is a MOSFET? I'd assume it just works like a fuse to prevent shorts. Please correct me if that's wrong. Also, how would I go about installing one? Thanks in advance!

A mosfet removes sending a large amount of current through the trigger contacts. They can also be used to program burst fire.
The advantage of the mosfet is that it eliminates arcing which can toast your trigger contacts, which aren't very fun to replace.
That being said, I run high discharge lipos in all my guns. My G&P with stock wiring and contacts has a 7.4v 5000mah 25c lipo in it. After a season of use, I did not see any sign of arcing on my contacts. I do not get too crazy on the trigger though. (11.1 lipos will be more prone to arcing)
If you are the type that goes crazy with really quick semi auto trigger pulls or sustained full auto, a mosfet is probably right for you. They do require a bit of tech knowledge to install correctly.

Alright, thanks. Honestly, I'm pretty tech savvy when it comes to the V2 gearbox, I just don't know a few things. I did install a new spring, motor, and bushings as well as having shimmed my own gun. So, to clarify, you just solder the mosfet to the trigger contacts? And does the mosfet replace my battery connectors?

There are a few wire diagrams for mosfets. The standard style with active breaking runs 2 signal wires from the mosfet to the trigger contacts. Then you run your heavy gauge wire from mosfet to motor. Your battery contacts come off the mosfet. extreme-fire.com/MOSFET-WiringDiagram.jpg^Here is a link to some diagrams.

Alright, thanks for helping, much appreciated. I may have to look into this a bit more, I thought all mosfets were like the burst wizard and just acted like a fuse. Thanks for clearing this up.

If you are the type that goes crazy with really quick semi auto trigger pulls or sustained full auto, a mosfet is probably right for you. I would say everything is accurate except for part of this statement. Sustained full auto actually puts less wear on the trigger contacts. Rapid semi auto shooters are going to see the most wear. Arcing occurs only as you are pulling the trigger. Keeping the trigger held down doesn't further damage the contacts. High current (those with strong springs or high speed gears) and high voltage (10.8v/11.1v) guns will produce more arcing than others. Keep in mind using a huge 7.4v 5 billion C battery doesn't mean you will have increased contact wear. Having a gun that draws a shit load of current AND using a battery that can supply that current is what increases wear (assuming voltage is equal). One benefit I didn't see mentioned is that you will see a small increase in ROF. This is because you are removing the trigger from the circuit that runs the motor. This reduces the electrical resistance. Sent from my DROID RAZR using proboards

I didn't see this until now, but please stop removing content from the first post in a thread. We don't lock or delete threads after a question is answered because they function as an archive of information. If somebody with a similar problem wants to, he could search for your thread and find his answer. Now, that's damn near impossible because we have no idea what your problem was because you removed the content in the first post. It's no different from deleting the first post in a thread, it makes the entire thread completely worthless.
Please stop doing this shit, it's getting really annoying.

But he probably won't, right? And he definitely wouldn't if I hadn't said anything. The fact remains, removing the content from the original post ruins the thread. You'd do well not to defend his edit.

Fish I'm sorry for the inconvenience this has created, I'll go back and edit the posts with the original information. I didn't realize that was a rule. I'll be blatant, I didn't read all the rules.

It's never too late to read them.
