Hey folks, I am pretty new to EV bikes, I'm putting together a nice commuter/cruiser with a 750W goldenmotor rear hub motor and cruise controller currently. I'm going to use it to commute to work which is 7.8 miles away, I can charge up at work when I get here, I doubt I'll be running pure EV, I want to pedal as well (help me get in shape and less battery run down).
I had planned on making my own pack using 32 D cells in series at 10Ah to give me about 380 watt hours give or take, however now I am doing more research it seems that most manufacturers grossly (lie?) overstate their amp hours on these D cells, particularly tenergy. I did find another cost effective brand out there "powerizer" but I can find little information on them?
I would prefer to stick with nimh chemistry as its robust and long lasting, does anyone know any good websites that actually test batteries and measure the real amp hours? I can't find any that do this, if not I might end up buying some single sample and making my own rig at home.
Any good websites for buying large quantities of nimh cells, I've found some online but not a loads.
I've even considered using AA nimh cells as some of these have solid 2.3Ah ratings which actually match the manufacturers specs. (there seems to be a drive for high quality AA nimh cells for digital cameras)
thanks!
