Description

Please read up on LiPo packs before purchasing.

Note:

These can be a tight fit. If they are, carefully sand down the sides of the end cap before inserting. If you try and force these in/out while tight or at an angle, they can fail as you force the end cap off (Each AEP LiPo has the end cap tested under our packing cameras to ensure they are not loose prior to dispatch of each order).

While removing these, simply lift the back end of the battery up at the same time as you use the battery release lever. Never try to use a damaged LiPo of any type.

ONLY USE A LITHIUM POLYMER (LIPO) CHARGER WITH THESE BATTERIES. USING A STANDARD CHARGER WILL DAMAGE YOUR BATTERY AND INVALIDATE THE WARRANTY, AND POTENTIALLY DAMAGE YOUR AEP.

If in doubt, call us before use.

We first heard of a LiPo conversion for your AEP a little over a year ago. It involved purchasing an adapter from a Canadian company which got physically soldered into your AEP. This allowed you to use a custom mini LiPo in your AEP removing the need for the poor quality NiMH batteries that come with the AEPs. Unfortunately doing this modification was time consuming, fiddly and invariably this invalidated your warranty.

So rather than go out and source these conversion kits, the boffins in our Technical Department decided to take a different approach. They directly contacted the manufacturer and sent detailed specs of the existing battery plus bare frames for them to play around with. Now, after some development and a few hand-made samples for test purposes, we can officially announce this new product to the Airsoft market!

Ditch the tricky DIY conversion and instead try this plug-in unit. It drops into the body just like your original battery but with higher capacity, better cold weather reliability and the bonus of a faster trigger response and a higher rate of fire!

But why would you want one? Well, put simply, it changes your AEP from a basic gun into a usable skirmish gun. It won't make you 'leet, it won't fire further or even change it's power. But what it will do is give you superb trigger response which was distinctly lacking from AEPs up until now.

We have tested the fitment and can confirm they fit into the following pistols:

CYMA 1911
CYMA Desert Eagle
CYMA/Tokyo Marui Glock 18C
Jieke/Tokyo Marui M93R
Tokyo Marui HK45

And with slight modification to the body:

CYMA 226
Double Eagle M81/Tokyo Marui USP

 

LiPo cells pack a much greater wallop into a smaller package than conventional Ni-Mh or Ni-Cd cells, however these are not for the beginner! On tests, the 7.4v packs are kicking out the same Rate of Fire as our 8.4v mini packs!

Warning:

Never charge these unattended.
Charge on a fire-proof surface.
Charge using a LiPo balance charger ONLY.

World Exclusive! Lithium Polymer AEP Battery (Li-Po / LiPo) 7.4v 550mAh

Great performance, poor cap
Review by Justin

I bought this for my Tokyo Marui Hi-Capa E. The performance is excellent with this lipo, it makes the pistol a formidable weapon with a 100rd mag on full auto. I was disappointed with the build quality of the cap. It broke off the second I tried to use it. One end of the cap was barely stuck on and I knew it would come off the minute any pressure was applied. A bit of fiddling and some new adhesive fixed it but not what you expect to do with a brand new product. Also I initially had a problem getting it to charge. The charger was displaying a "connection break" error message. Upon closer inspection I noticed the negative terminal had some sort of lacquer on it. I scraped this off with a thin blade and it fixed the issue. (Posted on 15/05/2019)

Better than before but still problematic.
Review by Colin

Having bought one of these before, I discovered that not only was the cap not secured but that the battery had been assembled incorrectly so that the arrow on the cap, which should point forwards when fitted in a Scorpion, actually needs to point backwards when inserted into the TM LiPo holder.

Having worked that out and glued the cap in place, I ordered two more as the Scorpion is amazing when run on a LiPo. When they arrived, I was pleased to find that both of the caps had been firmly glued in place:). However, the battery still needs to be inserted backwards into the LiPo holder. Clearly, it is not possible to correct this on the current batch of batteries but, hopefully, it can be sorted out in future. (Posted on 31/12/2016)

Good battery - shoddy quality
Review by Ben

I bought 2 of these, one worked fine, the other the cap fell off and the battery shorted out the first time I removed it.

This was not a rapid field change - I was being very careful as it says on the site, and sat at my bench in my workshop.

I put some electrical tape laterally over the cap on my other batery, and that seems to hold it in place well, and I will do the same for the replacement I've just bought.

But BE WARNED, the cap on these are attached terribly, and you will probably need to make sure it's well attached before using it. (Posted on 11/04/2016)

Attention Mac10/Mp7/Skorpion Users!
Review by steve

I recently bought two of these and the marui aep to 'cmg' adapter elsewhere on this site.

Two things;

1) The polarity is REVERSED when in the adapter!
I should have picked up on this with my smart charger, but i had previously unplugged my usual tamiya cable - aep adapter trying to charge with the balancer plug on the Lipo (cant do this lol)

I ended up blowing the fuse on my mac10 *THANKFULLY* nothing else. I only realised what had happend when i went to charge my original nicad marui and the charger moaned about the reversed polarity.

So, when putting one into the pistol aep to smg adapter PUT IT IN THE 'WRONG' WAY! Works and sounds great after that lol.

2) The fitting in the adapter is VERY tight. I managed to pop the cap off one lipo when removing it - fortunately the terminals didnt short and i was able to loctite the cap on fine and it still works. I've managed to remove a lipo intact on a second go, but it is very touch and go and really *really* doesn't want to slide out horizontally like it should do.

So, i would strongly recommend buying an adapter for each battery (only £5 each) with the intention of keeping in there for life!

In other news, my gun is sooo much more responsive now and in my limited armory is only beaten in ROF by my TM G3 hi-cycle :)

so to sum up;

*POLARITY IN IN ADAPTER IS REVERSED AND WILL POP YOUR FUSE*
*BUY AN ADAPTER FOR EACH BATTERY* (Posted on 04/02/2016)

i bought one of these for my cyma glock 18c and was not dissapointed, rate of fire is incredible and even ups the fps (only a little though) havent had any problems with this product at all, it fits perfectly and after everyones saying they are fragile i don handle them with care most of the time but have been rough with them a few times and... nothing, still working perfectly after 5 months, and i use them about 3 times a week, so if youre looking to get one for you cyma glock, dont think about it just buy it, you wont be dissapointed, cant say what its like for other guns though, so bear that in mind (Posted on 15/07/2015)

Not impressed
Review by Alastair

Bought this item as I was fed up of the poor trigger response from a nimh battery in my tm glock 18 AEP. However, on receiving the lipo I was not impressed. The item fit perfectly without any resistance and when ejected without resistance, the cap flew out and the terminals shorted. The fact that there is not even glue or another product used to secure the cap is disgraceful. Contacted airsoft world and got two quick replys from Duncan. Very polite replies but it was made clear to me that I was at fault and that a replacement would not be provided under warranty as I had voided the warranty. Would not recommend this product and I'm not satisfied with the outcome of this transaction. I understand the disclaimer is there for a reason, but the item was not up to spec.

These batteries are a very good upgrade for any AEP but the only minor gripe is they don't sell or supply a adapter for the contacts end to enable charging with smart chargers that don't allow charging or discharging with a balance port only. Otherwise these batteries offer a excellent trigger response and fire rate upgrade for AEP's. (Posted on 06/02/2015)

Is very noticeable improvement over using normal batteries.
Very good choice.

But you must be very careful when removing the battery because it takes very fair and cost it out.
Remove the battery slowly without forcing or you can break the contacts of the battery.
I recommend strengthening the area, sticking with loctite the two pieces of plastic wrap battery contacts. (Posted on 03/12/2014)

I wasn't convinced by what folks told me about these tiny but might batteries.
But I bought a pair for my TM glock18c and Oh My God what a difference they make the trigger response is sharper and rof on auto is amazing.
The only down side to them is, is that they are a little tight fitting under the barrel, as long as your careful its no issue but in the heat of the moment in the field...

All in all an essential item if you're serious about using an AEP (Posted on 17/11/2014)

Got my battery last week and after figuring out how to connect to my Vapex 600 charger I got a full charge into it for my CYMA GLOCK 18c.
FPS is the same (9ball spring+cylinder and piston head) 230/250 fps but the ROF has gone BONKERS!, 885 rounds/min or just under 15/sec.
NICE!, Trigger response is instant, my pistol has some real "Hose Down" ability now! 100 round mag essential. (Posted on 26/01/2014)

Bought a pair of these to use in my Cyma 1911 AEP. Responsive and 1 battery lasted me most of the game day without issue.

Unfortunately, as Elliot mentioned before, they are a very tight fit and it's important to fit them straight into the bay (parallel with the inner barrel) otherwise it's easy to lever the caps off and expose the metal contacts.

I've already had to return my first set of batteries and I'm thinking some strategic blobs of superglue if my current ones do the same will be a good idea.

Otherwise, I'll be buying more in the future as my arsenal gains more toys. :) (Posted on 13/01/2014)

Been hunting lipos for my electric glocks for some time now, as I'd rather not attempt to convert a lipo myself.
Saw these and grabbed them figuring, worth a try.

I'm rather impressed, a snappier response than the 8.4 batteries it comes with, and even snappier than the TM Pro light being used as a battery.

Only downside its a very very snug fit and a tad time consuming to change batteries, but, its a bearable issue. (Posted on 13/12/2013)
