I fly a hummingbird and normally charge these at the 1c rate as a fast charge with peak detect. Although this works ok i was informed on some web site or other that you should rest the packs for at least 8 hours between charges( which i adhere too). Is this right or can i recharge when they have cooled?

The older i get the faster i was

Charging ni-mh batterys

You are right in what you say ni-mh batterys realy should only be charged and discharged once in 24 hour period unlike nicad we abuse them thats what we modelers do best

I charge my ni-mh at 2 c as many times as i need them i only have two 7 cell packs that i have had since xmass and now they are past there best i was getting 11 min on my fixed pitch hummer now i only get 8 min time to invest in new ones

The best way is to charge at 1c and have more packs but if you have to leave them 24 hours after a charge and discharge then i think we are wasting our time and should seriously think alternative batterys like li-po longer duration

Maybe I understood it differently, but I believe it to be NiCad's should only be used once a day, while NiMh's can be used several times a day as long as you allow them to cool in between. When I was running electric cars, they were saying that actually NiMh's get better the more you use them that day. Good luck.
