My idea is to unbalance charge them at 5.0A until the battery has a nominal voltage of about 16.6-16.7v and then switch it over to balance so the cells are all the same. Does that sound like a good or bad idea?
Your problem with multiple cells and not balancing, give you a good chance of over charging a cell, boiling it, and catching the battery on fire. The only batterys I've ever seen burn, were being charged without balancing and were close to finishing (3). As far as charging, I've bought a Hitec X4 and a 30amp PS. It's been great and will charge my 6s at 5amp,5000 cell. But I think it's about the 30amp PS keeping the power clean. Hopefully you can learn from my earlier pain(LOL) and campfire car (I was lazy).
