Me and my dad used to charge all our rc airplane battery packs on power supplies for years without a problem. I could use a voltometer and check it's remaining power then use math to charge it properly. At least till I get my car then I can buy a second batter so I can basically loop. (battery 1 runs out, throw in battery 2. Charge battery 1. Run 2 till it goes out and throw in 1. Charge 2. Repeat)
