storing a 8.4 mini battery in collapsable stock?

[panda86]

I tried searching pretty much everywhere, maybe this is just an odd request.

Does anyone make a stock for the M4 (standard stock tube) that can hold 8.4V mini batteries? I've seen the Crane ones, etc.. but I don't really want to get all new batteries when I have a few mini ones that do what I want and work just fine.

I just don't want to have the fake laser battery box up front on my TM M4RIS , it's unbalanced as it is (front heavy), so I want to feed the wires to the back into a stock of some kind.

Any ideas?

Thanks in advance.

U could get a battery bag that fits onto your stock? if u want it to fit inside the stock tube your going to have to go LiPo

Not too sure about the stock part, but if worst comes to worst and you can't find a stock, mabye you could get one of those cloth battery holders that attaches onto the stock.
I'd show you what i looks like, but for some reason i can't find that video for the life of me...sorry.

Theres always the full stock option, it takes away the ability to have an extendable and collapsable options but with a full stock you can fit your 8.4 and in some cases all the way up to a 10 volt batt.

On my first armalite I thought the same thing, with in a few hours though I had changed my mind and the idea of the crane stock was more appealing by the minute.

I don't think there's a crane stock that exists that will hold a mini battery. The best solution would be a battery bag like this one: http://www.airsoftparts.ca/store2/in...roducts_id=421

It will attach to your stock and you can fit the mini in there. Alternatively there are battery slings that keep the battery on the sling so it's completely off your gun. They're a little harder to find and require a bit more wire though.

None of 8.4V mini batteries that I know of can fit inside an M4 standard collapsable stock (not a crane stock which can hold a large or a mini crane battery).

I guess that you should use Li-Po batteries to make it happen. I'm planning to do the same.

Have fun with that next to your face.

Don't talk about things you don't know.

The LiPosacks are made for CHARGING the battery.

The pack is perfectly safe when not hooked to a charger. And it also is perfectly safe when using the right charger and settings.

I have seen Ni-Cd and Ni-Mh packs explode a lot more often than any LiPo, causing a lot more damage (a metal piece flying around the place can be very dangerous).

Thanks for that, Captain Obvious.

Right. Ask Sony and Dell how well their lithium laptop batteries have been working out. Better yet, ask the assistant chief and captain of the fire department from this article about how their defibrillator battery exploded on them spontaneously while sitting on a desk. Or ask this group of R/C users - arguably the largest consumer group of hobby LiPos - how many accidents they've had versus nickel-based chemistries.

LiPos are an immature battery technology and far less stable than NiMH or NiCd. This is proven beyond a doubt through countless accidents and insurance claims; to deny it is asinine and ignorant. They can be used safely provided precautions and the correct equipment is used but people should NOT be recommending such carefree usage of LiPos without understanding that their use carries a significantly greater risk of damage and personal injury. Read that last link and take careful note of the respect and caution everyone extends to LiPo usage.

So the next time you want to throw around notions of speaking from the ass, do yourself a favor and make friends with Google first. It might save you some embarassment.

Thanks for the tips guys. I might try and make something that works (I'm surprised there isn't a stock for 8.4V mini's), or try the sling thing or the stock pouch.

That exploding battery vid is crazy!

[Gryphon]

It is worthwhile mentioning that LiPos don't just explode like that when being recharged or physically abused. Exceeding the discharge rate of the pack (ie. dropping in a heavier spring thus causing the motor to draw more current) can also cause it to blow. If you are aware of the risks then fine, but I really dislike seeing such casual and dismissive attitudes towards this battery chemistry.

[Kos-Mos]

Have you ever used any LiPo chemistry battery?

Doesn't seem to me.

The LiPo packs do not explode when over discharged. They inflate. They can explode on the NEXT charge cycle, or if punctured.

Dell's and Sony batteries are Li-Ion type batteries. Not LiPo. They exploded because there was a flaw in the CHARGING process used to recharge these packs.

The links you gave are refering to faulty use, bad charging, damaged packs and other non-apropriate use.

The ADF link talks about a 3y old pack, and that only 4 failed to work on 30 000. In the last 2 years, LiPos have become a whole lot more efficient and safe.

The RC group link talks about a whole bunch of faulty charging/discharging/damaged pack/over rated packs.

The 12 "Un determined causes" can all be related to missuse or insufficient rating.

Link 5: The pack was way under rated seeing the internal configuration used (a whole lot of packs in parallel, then linked in 2 large blocks). Over-rated.
Link 33: The pack was connected backwards when charging. Read the later posts.
Link 60: The guy left his battery in his car, under full sunlight. He could have left a bomb there, it would have done the same. Overheating.
Link 82: Two packs where left plugged in parallel, mostly discharged. Overdischarge from self-balancing.
Link 92: NO information is provided, causes can be anything.
Link 96: Damaged from shipping, airmail and poor packaging. Damaged pack.
Link 97: Green house effect under a grill lid. Overheat.
Link 101: The guy heated the pack to shrink wrap it. Overheat.
Link 105: Possible puncture of the pack. Possible overheat.
Link 78: The guy plugged a 7.4v pack in parallel to a 11.1v pack. No need to say more. Self balancing and fire.
Link 99: No information provided, story told by a friend of a friend.
Link 110: Different rating packs mixed in parallel setup. Different discharge = Overdischarge of one of the pack.

As you can see. If you READ the stories properly, all have an actual cause, most of the time the user.

You can try all these stupid things with a regular NiCd pack. It will be damaged and can explode.

As usual you're missing the point. You point out that LiPos fail because of user error and abuse. We're all well aware of that. What you cannot seem to grasp is there are idiots in airsoft who WILL abuse their batteries, connect them backwards, exceed their discharge rates (and unlike you claim, drawing too much current from a LiPo WILL cause it to explode), and the consequences will be far more severe than an abused Ni-based battery. Since I've provided you with plenty of evidence of the violence of LiPos, show us a video of a NiCd doing the same thing. Put up or shut up, pal.

Im using Lipo and Im having absolutely no problems at all. I also have a $30 shipped balance charger tha also works very well.

why do people think its that unsafe to use a Lipo? I have both battery and charger for only $60 shipped and it is as safe as it can get.

oh and you can't connect battery backwards, there's protection feature on the battery connector where one side is circular and the other opening is square, thus its impossible to connect them backwards.
