Electric Bikes - Sticky thread for batteries?

There's not much info about the Schwinn Tailwind on their website. Looking at
the size of the battery and the "small" motor, it should be capable of 50 miles on a charge.

The 3000 charges they claim would be a world record beater for sure.

looks like ping has a webpage now http://www.pingbattery.com/servlet/StoreFront

www.ebike.ca (http://www.ebike.ca) is a supplier of 24, 36, and 48 volt 12 AH batteries, and test them etc.


Yes, I have the same setup, with cycle analyst as well, have had the battery powering 408 motor for five months now, and just recently the voltage has been dipping far too early, way before I reach 12ah. In fact, the cycle analyst would cut off my battery at around 4 ah when my voltage dips below 42 volts. I contacted ebike.ca and like mentioned here, they will replace the BMS free of charge and they stated that the most likely cause is the old BMS not balancing the cells adequately.

They also offered to send the BMS replacement kit with instructions (http://ebikes.ca/BMS_Replacement.pdf (http://ebikes.ca/BMS_Replacement.pdf)) free of charge.

I like it.. i like it a lot!!! :D

I finally decided to write to FireFly Energy about the possibility of releasing a lead acid battery with their newer technology for bicycle use. Daniel Stewart of FireFly Energy responds:

"Thank you very much for your interest in Firefly Energy. I have to tell you though, that our technology is optimized for batteries with 25 Ah and higher capacity. Our first product, to be launched early next year, is a 100 Ah battery.

All this is to say that it's unlikely that we will produce a battery that will be applicable to electric bicycles in the foreseeable future.

Thanks again for your interest."

Time will tell, but Dan says bicycle users shouldn't hold their breath waiting for this newer technology from FireFly. ;)
