LiPo Stick/Nunchuck, etc..

Someone (sorry I don't remember who) had recently asked me for a cheap place to get nunchuck or stick type LiPo's...

HobbyPartz.com now carries them. Here is the link: http://www.hobbypartz.com/geacebaforai.html

They run anywhere from $8 to $12 each.

Damn, those are cheap. Can you link a good LiPo balance charger to go along with those?

This is similar to a LiPo charger I have, although the sticker looks a little different, probably just a newer model.

$15.90 - Free shipping

Thank you for the link, I've been looking for cheap 7.4 stick lipos that I could fit into a buffer tube.

The charger you linked us to (the sky one for $15) claims it will charge up to 3 cells. I was looking at the gen ace 1400mah 7.4V 20C battery (you linked us to the gen ace page) and was wondering how many cells it has, I think it has two, but it won't show me any specific number.

Each cell is 3.7V,

3.7V = 1 Cell
7.4V = 2 Cells
11.1V = 3 Cells
(and it keeps going up, but don't use a higher voltage for airsoft, unless you like destroying gears and pistons)

Yes, I knew about the gears and pistons parts, just was unsure as to the fact that one cell is 3.7v, but now I know. Thank you Twitch for your answer. What a Face

If they are improperly cared for they can become unstable.

The Boulder Brigade has a Field Training Manual for its Operators, this is an excerpt from it pertaining to LiPo batteries:

Brigade Field Training Manual wrote:
LiPo batteries are the current "cutting edge" technology for airsoft and remote control batteries. LiPo batteries will offer a stronger output into your airsoft gun, and should only be used in guns, in which the gear box is designed to handle them. The most common voltages for airsoft LiPo's are 7.4V and 11.1V (each cell in a LiPo is 3.7V) A 7.4V LiPo is equivalent to using a 9.6V NiMH, and an 11.1V LiPo is equivalent to using a 14.5V NiMH (this very quickly drops to 13V under load.) These voltages are approximate and nominal charges. A fully charged 7.4V will actually read 8.8V, and a fully charged 11.1 will actually read 13.2V on a voltage meter. A balance charger for a LiPo will not allow you to over-charge the battery. It will stop charging when the battery is fully charged.

When using a LiPo battery it is important to store the battery fully charged, or you will cause a premature death of the battery. It is important to use a balance charger when charging a LiPo, so each cell is charged at the same rate as other cells. This prevents over charging. Over charging a LiPo can cause it to catch fire or explode. LiPo's store an incredible amount of power in a very small package, so it is important to take care of them. Do not attempt to use or charge a battery which is damaged. Never fully discharge a LiPo battery, or allow its voltage to drop below 3V. Voltage alarms for LiPo's are available, and will alarm when the voltage is too low, alerting you to stop using it. If you discharge a LiPo below 3V you will permanently damage the battery.

No. If you want access to the full Field Training Manual, you would need to try out for the team and be accepted.

So, I'm looking into a lipo charger/discharger to get before broken home.
How does this one stack up to what everyone has? http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=6478
Are there better/cheaper ones out there?

by **Twitch** May 4th 2013, 16:30

Don't ever hook up a lipo to a discharger you'll destroy the battery and likely cause a fire/kaboom. Dischargers are for the nimh batteries.

This is the charger I use: http://item.mobileweb.ebay.com/viewitem?itemId=190784986866&index=10&nav=SEARCH&nid=45664877102
