li-po battery

[Dusti69]

hey just wondering if you guys think this is a good battery. i dont really know anything about batteries and less about li-po's. it has too high voltage i think and not much more mah than an average 8.4 nimh.
the price sounds amazing though

or fire.

Thats what will happen if you buy shit lipo batteries and a charger that isn't meant for charging them. But what do you mean is it a good battery, what do you plan on using it in? Don't skimp out..

double topic.. dam

Sure why not, it looks dandy.
As long as you have the proper charger you should be fine.

I wouldn't recommend it. From my latest li-po vs. NiMH tests, this won't work better than a big sub-C 7 cell 3700MaH battery. For a LiPo, the cost is good - but is it a good long-lasting battery??? I don't know the manufacturer. I hate the quality of chinese batteries - I've had nothing but bad luck at work and at home.

You'd also need to buy LiPo charging and balancing (ie. Blinky) equipment. Normal chargers will not work!

(Not slamming LiPo's, I own 10 and use them all the time up to 270Watts in R/C.)

i have this li-po set up that i got with my ika zuchi.

i dont know what its volts or mah is but evike has this one listed as 11.1v 1500mah. so thats what i have if this is the same set up i got. i would imagine i could charge this li-po with its charger.
it costs a lot less than the nimh 9.6 and 8.4 batteries. i only wonder if it would wear out my krakens gearbox. i kinda think yea it would if it does what the li-po does with my ika zuchi

I use the same brand of Li-Po(Firefox) since January.

A lot of people are using Li-Pos now for R/C Planes... after seeing what happens in a crash with a Li-Po.. I don't think I want to use them. In airsoft I can't see them offering any advantage over standard cells.

+1. I switched all my guns to LiPo. I run a Firefox 12C, 11.1v 1200Mah tri-stick in all my M4-based guns:

It fits perfectly in the handguards, even in places where a butterfly pack won't fit (ie: an TM RIS with a reinforced 1-piece outer barrel) and gives a crazy ROF.

I also bought some Zippy packs from here:

This pack, in particular, runs great in my 380 FPS AK47:

These ZIPPY packs re great packs for the money; unfortunately, they're so good they're almost never in stock.

I also bought this charger:

And this balancer (which apparently is the only weakness of the charger above) which was on sale for $10 when I ordered:
http://www.hobbycity.com/hobbycity/s...rger_1-6_Cells

And as cheap insurance, I bought a couple of these, which beep when my voltage drops too low to prevent over-discharge and fire:

wow... and that can happen in your gun? what would it take to cause that in your gun?
my chrager charges mine in i think less than an hour. i couldnt believe how quick it was

I've been in the R/C hobby for the past 8 years and have watched it grow and advance since then. Li-Po batteries, when compared with NiMH batteries of the same caliber, provide more amperage (power) at a quicker and more consistent rate (not using technical terms), in short they have a much higher discharge rate, major downfall is Li-Po cut-off voltages of course must be pampered (given you don't have a cut-off device).

So I guess this is my point:

Pros-Longer lasting battery (usually)
-Higher discharge rate (more power)
-much lighter in weight


Cons-Cut-Off voltage to worry about
-Can be very expensive up front
-Li-Po is till not 100% stable
-Specific chargers needed


Thats all I can think of for airsoft uses, feel free to edit and add guys.

Hey, I would recommend charging your Li-Po at a constant of 1C, meaning if your pack is 1500MaH charge at 1.5amps, 2700MaH charge at 2.7amps, and so on. It should always take an hour to charge your Li-Po safely.

Thanks, Rex

Unless you are blowing up a LiPo on purpose, the scale of what you have to do wrong to get it to blow accidentally will more than kill a NiMh pack. I have never heard of a LiPo pack exploding except on purpose, when idiots use them (wrong chargers and such), and super cheap Chinese brand ones.

Firefox is one of the best from what I have read, good quality but some Chinese companies label their packs "Firefox" but they aren't, so buy from a reputable retailer.

Advantage over NiMh? I can get 11.1V and almost 3000mAh into the size of a mini 8.4V NiMh, for the size of a large 8.4V NiMh I can get 9900mAh (yeah, overkill, I know.)

Do I use LiPo? Nope, I own too many expensive NiMh packs for it to be worth it for me to switch over, and my only guns are a PTW (official SystemA batteries), and a STAR M60 (massive battery compartment) so I have no need. Those that run guns with mini batteries and high fps upgrades its really worth it.

Any questions, ask Kos-Mos here on ASC or read his battery FAQ thread thats been stickied.

[Kos-Mos]

Read what they say in that video:

They are fast charging (usually 4-5A) a LiPo pack with a NiCd charger.

I am using LiPo's in my guns since 2003. Never had any problem.

And for your information, go look-out the tests that the ROAR (international RC organisation) put the LiPo to before saying it is dangerous.

Some examples:

-Drop the pack from 5' on a concret floor.
-Intentionally over-charging the pack.
-Driving a nail throught the pack and watch it NOT explode.
-Over-heat the pack.

The packs that are aproved are passing all the tests without any significant damage to the surroundings. That mean that if a failure has to happen INSIDE your gun, it won't do shit.

*edit*
Don't get the "FireFox" pack you shown. Looks like a crappy copy.

Zippy packs are know to be one of the best around.
You need at least 15C when you look for packs. That "FireFox" pack is a weak 12C. It probably won't be enought for an upgraded gun, might work for a short time on a stock one.

oh will you look at that, of course I didn't notice the stickied battery FAQ thread, it's only got a big sticky next to it. way to go kos-mos.
