Hey I got the charging solution for you if you can run 6s packs (A123 that is)
You can make in like 10 min a charger for 10 bucks that will charge a 3s pack at 10 amps and be done chargeing in under 15 min. Here is how.

Of course if you build 2 of these then charge 2 packs at a time. That give you a 6s1p 2300 MAH pack with a charge time of 15 min :)
It's working great. But Note it only works with 3s A123 packs!!!!!!!!!
