i use some 50w Chinese chargers. Ive used them for just about every size lipo, from 2s 1200mah to 5s 4000mah to 4s 5000mah. It will charge all those packs just fine. it just cant charge at 1C when charging larger packs. depending on how long in between races you have, you can normally recharge your packs in time. I can get away with a 50w charger for 4s 5000mah and use the one battery all day(well, it's 2x 2s packs, but i charged as 4) for 2 5 minute heats and then a 15 minute main. there are usually 6-8 classes running at the track too.
