Hello to all of you, I have been inactive on the technical side of ebikes for several years. Previously I was a field person for Giant's ebikes, Bionx, Cyclone, and several others. I have built maybe 50 ebikes for customers and maybe a dozen for personal use from 2001 to 2015. I had a...

not 24v but did a 36v nimh to 36v lithium in a rear soft pack. the electronics would be easy, physical size is challenging.

did it overheat when charging to 26v? if no, then you have an open circuit somewhere you should resolve. if yes, then it is toast. dick

hit an unavoidable patch of mud, blind downhill corner, oncoming bike. dislocated tailbone. medical copays much higher than cost of replacing the tire on time.
