    Using a tool battery as a small motorcycle starting battery?

    I have been trying to find a small starter battery for my little 400cc yamaha xs cafe racer. I bought a motorcycle starter battery that was just a small 4s lipo which died the first time the headlights drained it. Huge waste of money. It worked great but with no lvc the headlights kill it in a...

    Enertrac still only motorcycle hubmotor option?

    I have been building a cafe racer/scrambler on an old 1979 yamaha xs400 bike. I have been avoiding working on the drivetrain in case I decide to go electric. Even though its a 400 it is a small light motorcycle. If I can convert it to electric for about three grand I'm ready to pull the trigger...

    can my cellman pack be revived?

    I have a 16s 9ah cylindrical cellman lifepo4 battery thats been left drained for a couple months after the charger bit the dust. Is it toast or worth buying a new charger to see if it can be revived. If so where can I buy a cheap charger with a credit card? Thanks for any helpful replies.

    So how do we get the texas instrument bms?

    How do we get them and use them? $2.70 bulk price seems great for a 10 cell stackable bms. I have just begun playing with lipo and this fall when my job picks up I want to play some more and build a couple little projects for my friends. Since they will mostly being using them drunk and high at...

    Currie throttle question?

    This winter I am going to rebuild my ebike with the main upgrade being a larger higher voltage battery. So I stuck my old 36volt ebikekit battery on a e-zip 500 currie scooter. The throttle on the scooter is busted, I fixed it as best I could with some epoxy putty but I have a feeling I am not...

    Hobby city connector question.

    I am ready to buy either two turnigy or zippy 6s 5ah battery packs. I would like to buy a premade parrellel and series harness. I want to run them at 22v on my izip scooter and 44v on my ebike.

    Probably a stupid question but...?

    Do dc-dc converters go the other way? could you up your voltage with one? If that were possible I suppose I would have heard about it by now. But the thought of getting a single thundersky 40ah 12v battery and just using a converter to achieve any voltage I desire is so tempting. Whats wrong...

    One piece crank coaster brake gearing?

    I have a 36 volt ebike kit on a old single speed jamis cruiser with a 44t chainring and a 18t rear cog. As it is now I don't really have the option of pedaling to help my range so I would like to either get a larger chainring or preferably about a 15t cog. I have been unable to find either...

    Just broke my 2nd schwinn rack.

    Fool me once shame on you, fool me twice shame on me. Anything new that says schwinn is crap. It's such a shame it used to be such a good name :( I think I'll try axiom next but it's annoying you can't get something as simple as a rear rack at these "superstores". They have all these great...

    Question about parralell battery packs?

    I recently put together a ebike from e-bikekit.com complete with their 36volt 9ah battery. I am satisfied with the top speed but wouldn't mind a bit more power and range.
