Lithium Charging and Balancing Circuit Needed
 

I'm in need of a small Lithion-Ion or Lithium Polymer charing and balancing circuit. Ideally it would be a PCB without a housing or anything, and less than 3" square and 1/2" thick. But, I'm open to seeing what's out there. It needs to be able to charge a 6S2P lithium battery (at a slow rate).

I'm no expert in the area, but based on the charges I have seen/used for my lithium batteries; that size requirement is a little harsh.

I've been looking for a couple days, but probably not in the correct places. I don't want a hobby charger, I want something designed more for an OEM application. Also, it needs to take DC current as the input.

This post isn't really too much of a help, besides marking off websites that have been checked out. Sparkfun had these two, but they don't have enough spank for the 4400 mAh 22.2V battery you are looking to charge. Sorry :/

I would not ignore RC shops, they often have exactly what you're looking for.
For example, TowerHobbies has this this balancer (up to 6S).
Also, if you buy the LiPo packs there, they usually come with tiny load balancers shrink-wrapped to the cells.
