    How to put 2 batteries in series?

    I have two 48 volt 20 amp hour Calibike batteries and was wondering how I could put them in series, but also limit the voltage going to the controller. I know fully charged they reach about 108 volts, but I would like to figure out how to limit them to a 72 volt setup without bypassing the BMS...

    Would this motor work with my sensorless Lyen controller?

    My small 250 w hub sensorless hub motor just grinded itself to a halt on Sunday, so now I'm looking for a replacement for my fat tire ebike. I have a Lyen sensorless controller and this motor seems to have a lot of wires coming off of it. Can someone help me decide if this motor would work...

    Is it possible to connect a BMS to 2 batteries?

    I just recently bought a triangle shaped battery from Calibike.com that came with a BMS installed. It is a 48 volt 13 series 9 parallel made of 18650 cells. My other battery is a 48 volt 15 series 10 parallel also 18650 cells. Is there a way of connecting these two batteries using the 14 pin...

    Putting a Car Horn on my bike?

    I have been toying around with a dual tone car horn rated at 12 volts. It works great when I hook it up directly to a 12 volt battery, but when I use my DC-DC converter from Edward Lyen the horn will not function. I have tried running fuses from 10-30 amps, but there is no difference. Other...

    Electric Bicycle Fan

    I was thinking about adding a DC fan to my electric bicycle for LSU football season, but am limited in knowledge about DC motors and what would be the best for cooling and not too heavy. Something that would run at 12 volts would be nice. I want the most powerful thing I can find because...

    Help I accidentally broke my BMS!

    I bought a 48 volt 20 amp 14s Lifepo4 Battery off Ebay and I accidentally scratched the circuit board. I believe the battery has a max discharge rate of 60c and a continuious 40c. Now I am looking to replace the BMS board, but it has to be for a 14s battery. If anyone knows anything about BMS...

    Lipo question?

    Hi I was wondering if a HobbyKing Lipo 7.4 volt battery would power something that is 9 volts? I have an infinite sustain system on my guitar. It runs off of 9 volts, but if you go over 9 volts it will fry the unit. It works best with a new battery and I bought rechargable 9 volts but they...

    Will my motor work on this wheel?

    I bought the Mongoose Brutus and I have a hub motor currently attached to a 20 inch wheel. I have been told that the current motor will be too fast for my new wheel. I bought a Lyen controller and a usb programming adaptor, so I thought I could control the speed using lower speed settings...
