The charger that I want to buy is the great planes Triton which will do 1 to 24 cell charging+ 6/12/24v lead-acid and 1-4 cell LI-onand Li-po packs discharge and charge. Just incase you decide to try small parkflyers. $129 @ most LHS and you don't need to soder the cells just get the adapter that fits your TX pos and neg terminals correctly and attach them to the posts on the charger
