Li-po battery safety

sopmod · May 2nd, 2009, 16:39

Hi, ASC members.

I am looking to get li-po battery for my M4. I wonder if li-po battery need to be discharged after using it because I can't find discharger for li-po battery anywhere.

thanks

Discharging a LiPo is one of the worst things that you can do to it. It should always have at least a bit of a charge in it.

You do not discharge LiPo batteries in a discharger, when you notice the ROF decrease in your gun, disconnect it and stop using it. The load has to be removed as soon as the voltage drops below approximately 3.0 V per cellor else the battery will subsequently no longer accept a full charge and may experience problems holding voltage under load.

After a game, just top the battery up using a balance charger.

over discharging a lipo can cause it to blow up next time you'll try to charge it... personally i use this http://www.hobbycity.com/hobbycity/s...idProduct=7224 this one is for a 2 cell lipo (7.4v) but there is other versions for 3 cell lipos. this thing warns you when your battery becomes too low so you can stop using it. i also got this little tool http://www.hobbycity.com/hobbycity/s...idProduct=7704 it indicates the voltage of each cell

Make sure you read up as much as you can on LiPos, used improperly it CAN be very dangerous.

thanks for the tips guys. =)

Im glad that i understand how to handle li-po properly now.

You don't have to baby them you just need to to be mindful that they aren't NiCad or NiMH batteries and as such need a little more care. I Love the LiPo that I have in my KWA and wouldn't trade it for all the NiMH's made in China.

i'm sold to lipo batteries, currently i have 2 7.4v and 1 11.1v and i wouldnt go back to regular batteries

Me too, From what I knew that there are only a few redneck in Montreal who risk to blow up their head using Lipo battery include me and you. lol

I wouldn't trade pile alcaline, lead acid, or a hamster on a generating wheel for all the nimh's in china LOL

Lipos rock!

If you want to run lipo, king arms makes a protection circuit that will cut off power to the gun when the battery runs down. Press the reset button and you're good to go.
There are also charge meters available cheap.

New type lipos are safe and easy to use. They last all day. I blew through almost 4000 bbs yesterday without any problem.

I'll never use regular batteries again.

So this cell balance charger does what exactly? I keep reading about Lipos but I still don't exactly get them...
And what's with this I hear about getting a fire-proof bag to charge them in?
Aside from Rof and duration of use, is trigger response affected?

The balancing tap on the battery plugs into the balacing port of the charger. The "regular" ends of the charger and battery hook up as normal.

The balancing portion of things allows the charger to see each cell of the battery pack and alter the amount of power going to each one. That way it can see one getting charged slower than the others and bring it back in line.

There are simple precautions to take with LiPo's...the same precautions that should be taken with other batteries in fact...but "regular" batteries don't burst into flames if you treat them badly and over charge them.

LiPo batteries are no different from other batteries. A large voltage battery will result in a high ROF and quick trigger response. A large capacity battery will result in a higher ROF and all day shooting goodness.

LiPo's have the characteristics of being able to store and discharge power that delivers the effects of larger batteries in a smaller format.

So in "stock tube" setups or AEGs that just don't have the space for larger batteries, LiPo's can offer an alternative that will provide a good rate of power in a small form factor.

There's other LiPo threads where some of this has been covered.
