Li-Poly battery-LINK FOUND!! :O + PICS

[Polo609]

I stumbled apon a website sparrowunit.smugmug.com and this team has an amazing selection of m4's and real steel parts (vltor casv + stocks) attatched to their aegs. I have been looking around and also found one of the members posting on airsoftplayers.I asked myself where the hell does the battery go and how in the world does he get a real vltor stock on there with no fitment for a battery in the comparments?? Well the answer is a li-poli battery wich is about half or 1/3 the size of a 8.4 or 9.6 v battery and carries an 11.1 v charge. The mah is supposedly much higher then 3-4000 yet is still kinda safe as long as u dont spray 10000 rounds in a game. I also found the website that sells these batterys but i dont have the link here as i am at work. I will post up when i find it. But for those of u looking for a alternative for a battery and dont feel like getting a crane stock or battery pack or redi mag, these powerful batterys go right in the handgaurd!

First of wouldnt 11.1 V be too much for your gun to handle? Secondly these batteries are pretty expensive, probably twice the price of the others, but they do last forever. Lastly Yea they are smaller but are you REALLY going to notice the weight difference? There like half the size of a normal batt but still. Also you should look into rc sites such as a sight called tower hobbies http://www2.towerhobbies.com/cgi-bin...=++&search3=Go , they'd sell em forsure. One last thing im not sure if they would have the same fittings as the normal batteries. The ones i saw on the above^ site were for recievers in rc cars, to power the controller and servo's, not the motor.

i saw what it looks like and let me tell you, it is p-i-m-p. I dont think its that comon..YET..but i saw a battery plus the charger for 109.99 US. It was a us based store. Also it was written that you can charge the battery up to 1400-1500 times, and doesnt have to be discharged!

Ill post the site tonight, everything is explained, 11.1 is high, and probably not recommended for a stock TM gun, anything slightly upgraded will handle fine. As long as your not using a box mag or go all out. The battery i saw was made for airsoft with tamiya connectors.

i can run my 400fps guns on a high drain 7.4 lipo. I use a lipo for my mp7 as well. all i can give for info is research lipo's, don't cheap out on charger's, get a balancer and take VERY good care of them or else you're in for a nice exothermic surprise
A good site to read up on them is rcgroups.com in the electric airplane section they have a subforum for chargers and batteries

[Gryphon]

I'm still not convinced of Lipos for airsoft use. In certain applications yes, they're appropriate and probably safe (the MP7 being a prime example). However lithium batteries are still not a mature technology as Dell's latest problems with Sony cells clearly illustrate.

Think of it this way. Should a Lipo blow in your gun, what will likely be next to it? A) your hand, B) your face. I went with a 4200 mAh NiMH.

I thought laptops uses Lithium Ion batteries much like a cell phone. And isn't Lithium Polymer a bit more stable than Lithium Ion?

(Not familiar with battery technologies)

I mean it would be nice not having to carry an AN/PEQ box on my M4 w/ MRE installed. Or at least it'd be nice to have a choice.

I'm home, will post link in an hour or so!

REVIEW

This battery is currently one of the best battery we have to sell for Airsoft. It's output and performance is simply amazing. They are currently the strongest battery our technology have to offer. They react different from NiMh or NiCd batteries, therefore, we only recommend experienced players who knows how to handle an upgraded airsoft gun to purchase this item and please read all of the following before your purchase.
This battery is smaller than a 8.4v 600mah mini airsoft battery. But the output and duration of this battery is more than a 9.6V 3300mAh battery! (To many experienced Airsoft players, this means "Problem solved".) This is a red alert generation two Li-poly battery and currently one of the best Li-Poly battery in this price range you can get for an Airsoft gun. (The next level up is a 50AMP output for around $250.)

Putting this on a M120 spring upgraded stock gun (with no high speed upgrade of any type) will give you a stream of bbs going out of your gun at the fastest cycle rate possible while at high velocity. The response time of this battery on single shot firing is almost instant (where on regular batteries you will experience a little delay.).

Evike.com have already had a few local players tested out this battery on top of hundreds of airsofters in Taiwan. A few myth of Li-Poly batteries has been solved.

They will not explode. Li-Ion is liquid and it might if abused. Li-Poly is solid and so it will only expand if you abuse it. We have conducted a test of rapid firing this battery for a few thousand rounds without giving it a rest and the battery got a little bulky and hot. This is under extreme use and should not have been done to your gun even with regular batteries. Take bursts in your shots and if it gets hot or out of shape, give it time to rest.

Many things that 11V is too strong and it might damage the motor. The truth is, this battery outputs at 11V max so it is only a little stronger than 9.6V at full auto firing.

Myth also state that this battery might wear off gears faster. It is only partially true. If your gear's cycle life (depends on brand.) is 50,000 rounds, this battery will probably help you reach that number faster because of it's super high firing rate. (But having 10 bbs coming out of your barrel at a quick trigger pull will definitely give you an advantage in your games!)

Li-Poly batteries are not like the NiCd or NiMh batteries. They have a much longer life cycle. You can recharge it about 1400~1500 times. But just like your cell phone batteries, you need to keep it charged and storage it charged. So when you are done playing, just put it in the charger and charge it full. (The charger included with this package will indicate a full when it is, there is no need to discharge this battery so DO NOT plug it into a discharger.)

Each battery is fully tested prior to your purchase. We warranty this battery for manufacture defective only. Due to that we do not sell used batteries, evike.com does not take any returns on batteries that are not a defect, please be serious with your purchase. Warranty is voided if the battery is altered, charged with the wrong charger, over heated or not in original shape. We brought in this battery due to high volume of request, and we can honestly tell you this is one of the best battery we carry that you can get. Due to the high power of this item, this battery is for experienced players who fully understands all of the above, we are not responsible for any damage of any type caused by this battery.

This battery must be charged with the supplied charger or a Li-Poly charger, all other chargers might damage the battery.

Intresting. Sounds like an investment...
I might try it later. I just ordered 4x 1200 nimh mini battery packs for 55$ Cad.
I think I'll stick with those for now...

I'm staying away from the new LiPo manufacturers until they have some better known history for a few years. So far I'll trust Kokam cells as they've been in the r/c game for a few years now and I've intentionally abused them to try to assess how they fail.

Clean manufacturing techniques are very important in Lion batteries. All it takes is contamination from a metal burr or a faulty self protection circuit to cause a bad failure. I'd put more faith in an older battery design from an established manufacturer than anything cutting edge from a new manufacturer.

On a more specific note, I'm not too happy how they skipped over any circuit protection features. LiPo batteries require built in protection to interrupt current flow in case of: overdischarge (run it down too far), overheating, excessive current draw, overcharge.

Some system designers put the protection ccts in the pack, sometimes they're put somewhere external to the battery. In any case they're necessary so they're issues to be addressed.

The separated cell setup is a nice way to distribute the thin individual cells in available space. However, I wonder if they're more prone to damage because they're individually more prone to bending.

Well said Carl.

I'd stick to technology which has been around for awhile/years. People just recently started to have Li-po packs in their RC car. Before it was all about the NI-CD and NI-MH.
I will wait awhile for the Li-Po's to become popular and have airsoft companies to adapt to the technology. Such as TM, Intellect Brothers.

Or maybe! Carl this could be your new project! In selling Li-po battery packs for our airsoft guns! :-D

[MadMax]

LiPo has been out for some time for R/C cars and before that even r/c airplanes.

I've been running LiPo in my P90 for quite some time now and have had very good results. I use Kokam cells which have been out for some time now. Extreme performance, but I'm not sure I'm willing to carry them until I see manufacturing techniques stabilize a bit more. I'm very leery of the new asian companies cropping up to push LiPo. It's possible that some of them are the ones with the real experience manufacturing LiPo and they've been supplying all the laptop and cellphone manufacturers all these years we've been carrying LiPo and Kokam is a bunch of amateurs serving the goofy small hobby market. Unfortunately I do not know enough to differentiate between all of the new asian companies jumping out with LiPo and my only experience is with Kokam.

I've just seen the direct results of shortcut taking in the manufacturing of mechanical products in China. While Chinese contractors are generally diligent, they sometimes cut corners where they don't appreciate the full ramifications of their economizing. With consumer mechanical stuff, you get creaky crappy flexy products which break. With LiPo you make nice little chembombs which occasionally rupture a separator (with a metal burr) and burn down. I'm just not ready to bring customers an exciting new product in an early phase of manufacturing/safety learning curve as nearly every battery technology we have to date has already passed through.

LiPo seems scary to us now because we're seeing a newish technology which performs extremely well compared to it's predecessors. The high performance of LiPo has forced competing consumer electronics designers to roll it out quickly to provide powerful compact electronics before.

NiCd has caused it's share of fires. Lead acid has caused some hydrogen related accidents. Then there was the good old molten liquid sodium batteries from the earlier days of electric car developments which caused some incredible fires in R&D labs.

This is the best place for LIPO packs

i find with my 8.4v mini, i cant double tap, i never use auto, so if i can decrease the sapn of time it takes to draw the spring and fire, would this be the kind of battery to get?
