So I'm due to get my first first gun soon (a ICS L85) and I've been advised by several people that a good battery to get is a LiPo one. In particular a 7.4v 2600mah Crane Stock.

I've been doing some research on batterys and know that LiPos offer better performance but need to be handled correctly. Seeing everal youtube clips of flaming RC planes is making me have second thoughts.

I understand that they shouldn't be allowed to run down too much? I'm gonna sound stupid but does that mean that you have to keep charging them when if you don't use it fort weeks? If so how often? What happens when you go on holiday? What happens if you do let one completely run down?

LiPo batteries are safe providing they're used correctly. Thankfully the rate at which they lose charge when left alone is VERY VERY slow, I wouldnt worry about one burning your house down while you're on holiday! If you're really worried about it though, just keep them in a LiPo storage/charging bag, they're made of fire retardant stuff so even if it does go BOOM the damage will be minimal.

 
Thanks for the advice.

Can you advise me on what you mean by 'used correctly' I've see lots of reviews that say things like that but not sure what that entails.

have a look in Ed's L85 review, iirc he uses 1000mAh

i don't think you would get a 2600mAh battery in the foregrip :wacko: but i may be wrong

 
Really? Damn. The nice man in the airsfot shop advised me to get those. Maybe I'll pop back in and ask him to show if they fit. Don't want to get lumbered with batteries I can't fit in my gun.

So, if Lipos need to be constantaly charged? How to shops and warehouses store them? I can they be left for months and months?

they dont need a constant charge, they just need to be kept charged ;)

you will know when a lipo is running out of juice as you guns response/ROF drops alot suddenly :huh: :o

 
I have LiPO batteries. Buy a dedicated charger, charge them up and then disonnect.. They have a very small self discharge rate so will stay charged between skirmishes.

Make sure you get the right voltage and physical size for your gun and consider buying two if you are going to be out all day.

Okay, I know I'm going sound even more of an idiot here. But what's that difference between having a constant charge, and being kept charged?

My understanding is that you can't let them run down to being completely empty, if you do they will become damged. What I'm really trying to understand is how often do I have to ensure they haven't run down? Do I have to check/charge them every week? Month, two months, six months?

Put it this way, if I fully charge a lipo battry and leave it in draw somewhere.... how soon do I have to go an check it's not totally run down?

The discharge rate is very slow, I would check probably every couple of months.

 
Just get a nimh, less expense. Seen and used Lipos and unless you want to increase the rate of fire, i dont really see much improvement for the cost...

Just my thoughts on the issue, seems alot of hassle for a massive difference on the day.

(Though to add, if your gun has an annoying battery compartment involving minor surgery to get one in, lipo's can be usefull as their shape is whatever they are molded as)

 
Also I think NiMH lose quite a lot of charge if you leave them standing a while.

Its OK if you are organised and remember to charge them up the night before a game but if you are a last minute kind of person, there may be some benefit to the LiPO route.

You can buy a little Lipo alert unit for about £2 that plugs into the battery and beeps if it's close to dieing. They sell em at Wolf Airsoft in London and am sure you can get them online. Saves the hassle of rigging up your gun every time you want to check the charge

 
I was running a 7.4v 2200 LiPo on my L86 Carbine (ICS) and it would last me well over a days skirmishing. Running 7.4v 1300 nunchucks now I have the DD rail fitted, am in the middle of a re-wire at the mo so not sure how long they will last but have 2 which should be plenty.
