Kat...not sure whats going on with you batteries as I havent read this post extremely closely,but it sound like I'm in the same boat as your when it comes to charging multiply batteries in order to fly the next day. And I'm just ahead of you as far as experience and needs go.So heres what I DO know...

This is an ABSOLUTE MUST.....

This is(as Ken recommended) my next purchase,and is llikely gonna work great for what I need along with my wall wort chargers (the chargers that came with my futaba radios). And I'll likely also say one day that it will be a MUST HAVE. And it will charge 4 batts at once at close to what wall worts charge at (I think).

If you use these and charge them at close to whatever mah (70 I think) the wall worts charge at for 12-14 hours before you fly....you'll have nothing to worry about. If it dont work,something is wrong with your batteries.
