Hey, well I have never ran a lipo in my gun before. and im new to the whole ordeal. I want and need to go lipo for size reasons. a small lipo will fit in the UBR buffer. but idk how "LiPo ready" my stock King Arms motor/ gear box are. and considering the huge price tag on mosfets I would like to know if they are needed.
my current price tag on my new loadout is over $600 as is, and really dont want to buy anything I dont need.
I did do a search on the site already for anything mosfet, but I never found what I was looking for. thanks for your time.

Also want to know as only Lipo will fit in Prime LR300
-
Just get an Infected or Mystikal fet for like $15-20 and a lipo from hobbyking for like $12.. Mosfets aren't needed, just highly recommended, especially on high discharge and voltage lipos.
-
well for the UBR best bet is the KA mini. and I dont trust the cheapo brand lipos, given their volatile tendencies. and at this point even $20~ is a lot as im pushing $700 as it is.
-
I run a 7.4v 25C lipo without a mosfet and its just fine.

As Matt stated all my 7.4v lipos have never fried my electrical contacts which is the biggest problem I've had with the 11.1v x20c or 25c lipos. I also have had good luck with 11.1v x 12c or 15c rated lipos without a mosfet.
The best part of using a mosfet aside from the voltage protection is with active breaking which allows for more consistent gear cycling, which may give you a more consistent overall FPS from shot to shot.

prehaps I will moap around the internets and see if I can find a small enough 7.4 from a respectable brand. Yet my past luck says no.

You do realize that King Arms doesn't make batteries, right? I wouldn't call the LiPo's they brand "respectable". I've got like a dozen Turnigy LiPo's and a handful of Tenergy, Flightmax, and Firefox LiPo's. I haven't had an issue with any of them. Just get a good charger and I'd recommend a stand alone balancer.

I understand that king arms does not make any form of battery. The reason I was looking at the KA mini 11.1, is because it is recommended size wise for use in the UBR buffer. I was hoping the LiPos KA puts their mark on would have the best chance for working with my KA internals. Considering those are the ones they would use for their testing.
and by respectable brand I meant, those LiPos are "approved" for airsoft use. Most of what I could find from turnigy were for hobby projects like rc power units and what not.
but then again like I said, idk much at all about LiPos and their brands, which is why I am here asking the question in the first place.
and if you dont mind, which charger and balancer would you recommend/ which do you use?

"Airsoft" LiPo's are, as a whole, over priced, under powered, moderate quality LiPo's. The ONLY reason to get an "airsoft" LiPo is because you can't find a regular one that will fit where you need it to. I get most of my LiPo's from HobbyKing. As far as charger and balancer goes, I use Kong Power's Charger and their stand alone balancer. I've been VERY happy with both products. The standalone balancer is small enough to fit in a pocket or pouch so you can use it to check your voltage on the field at longer games.

Ding ding ding. Best answer. If you're paying $65 - $80 for a Lipo battery from an airsoft store, you're getting hosed. The dangers of Lipo, and needing to be "lipo ready" have been sufficiently neutralized. Your motor / electrical system in your AEG will only draw what it needs, with the discharge rate determined by the battery.
You can get a 1600 mah, 15C 7.4v 2s lipo with deans connectors pre-soldered from EAB for less than $20 + shipping. There are some pretty good chargers and balancers that you can buy from overseas (you just have to wait for the slow shipping). Add an LVC device, deans connectors, and a low resistance ptc fuse to your wiring harness, and you'll still end up spending less than if you bought from an airsoft store.

Exactly.. I've only had experience with the nano-techs, Firefox, and turnigy lipos. All are relatively cheap but have never let me down

Thanks for the info guys. I really need to look at all the different brands now. Should be able to find something that will work for me. I will try a 7.4 1600mAh if I can find one, that will fit in the buffer. and hopefully that will last. Down the road I can up it 2 a 11.1 and pass it through a mosfet. Also is finding those LiPos with Tamiya connectors a fool's earand?

Here's my two cents. From what I've read you don't want to spend much but are hesitant to buy a "cheap" lipo. From my experience I'd recommend this for your situation, this will fit in a standard M4 buffer tube. I'm not familiar with the magpul set up, but if it uses the same stock buffer tube then you're good to go. It's cheap enough you can try it out and then decide where you want to go from there. http://www.ebairsoft.com/firefox-111v-1100mah-lipolymer-battery-short-p-2088.html (http://www.ebairsoft.com/firefox-111v-1100mah-lipolymer-battery-short-p-2088.html)
It's Free shipping, just may take a few weeks and it already comes with the Tamiya mini connector. Although I would highly recommend converting over to a deans connector just to prevent possibly buring out the tamiya connector. Over a year, I have burnt through 2 of them with standard NiCAD's due to the fact they are only rated for 10amps. But you could easily run it until you have connection issues, then I would change connectors.
As for chargers, you can get nice ones for cheap too. Just make sure it charges Lipo's, this ones nice cause it can charge other battery types and can run off your car battery. You may need to make your own charging connectors. http://www.hobbyking.com/hobbycity/store/__7028__Turnigy_Accucel_6_50W_6A_Balancer_Charger_w_accessories.html (http://www.hobbyking.com/hobbycity/store/__7028__Turnigy_Accucel_6_50W_6A_Balancer_Charger_w_accessories.html)

Thank you sir, very well thought out and links are great. I may just go with that LiPo.
-
you can get them cheaper on ebay i just bought a 3 cell 11 1200 20c for 11 bucks shipped. I would suggest a tenergy charger with built in balancer for you to start with cheap and it works and its shuts off when full charged to not over load a lipo. Also something not said yet you want to invest in a lipo sack. Its a flame retardant pouch you put your lipos in while they charge if your charger ever broke and kept loading your lipo it could burst cause chem and real fires. Dont get scared from this because normal batteries can do the same thing. I just think its worth the money to not come home to no home.

to help you I personally dont really feel lipo puts a ton of stress on guns as much as most noobs want to believe. The one really over looked factor is every airsoft gun is going to break its a madder of how many bbs. A lipo just gets you there faster if you were gunna break your gun in 100k rounds and on an 9.6 your shooting 10 and lipo 20 your gunna get to 100k twice as fast. Will it put added stress sure but most guns stock a able to keep up with speed. Its just how long it will last. crazyNC man put like 20-25 high caps through some crapy 50-70 buck gun with an 11 20c lipo.
