What are these batteries?
 
Hey guys my moms laptop just kicked the bucket.. i was wondering if someone could tell me what kind of batteries these are.. the case says 10.8v 4400mah and there are 6 cells.. so im gessing its just a li-ion 2200mah cell?

think they are worth running?

They're by LG. 3.6v 2200mAh is correct. Doubt they're much good for anything other than their original purpose. Most cylindrical Li-Ion have low discharge rates. There are a few out there that will do well though in higher draw applications. I have several old laptop packs I've dismantled. With 3 of the cells in series you can make a darn nice TX pack. I have three made from sony cells.

i was just thinking tht....im running 4x AA's :D :yipi:

i guess thats what they are going to be

83gt 07.27.2008 07:18 PM

not sure if you could run them as an RX pack. 4 aa's is 6v, and 2 of these would be 7.2v. might be tough on the servo's and radio. I use 3 of them in my MX-3s radio's.

howd u fit them in there?

3 of them wired sxs will just barely sqeeze into the battery tray. It does sort of bend the cover out just a hair, but so far no problems. They charge quick, and last for a very long time.

you could use them as rx packs with a voltage regulator like novaks or use an ubec

83 are you talking about rx or tx packs... sorry for the confusion but it sounds like you mean tx...

lutach 07.27.2008 08:43 PM

Don't try it. The first blip of the throttle you'll be needing a fire extinguisher :lol:.

brushlessboy16 07.27.2008 08:47 PM

ill run 3s2p :D

lutach 07.27.2008 08:58 PM

You could run 3S10P and you will still need a fire extinguisher. Those cells are only good for 5A max draw.

brushlessboy16 07.27.2008 10:13 PM

oh.. then.. um yeah probably gonna blow em up :D

I meant TX. 3s Li-Ion in my Aitronics TX's charge up to 12v, and last for a very long while. I have not seen any ill effects from this and I've been using them for about 6 mos.

Why not just blow 'em up? You don't seem to have problems doing that with other laptop packs... :tongue:
