Re: How to use a 60v battery pack on 48v motor

if your controller can take 60v it will be fine just keep an eye on motor temps and avoid WOT if you find it gets hot

To judge by how often they need to be bled to have air removed from the lines, lots.

And of course, whenever they're crashed and the hoses get yanked.

never had issues with that and i do ride some crazy tracks

You'd be surprized to know how many bikes on ES are beating the 60Mph.

rumme, if you want to build an e-bike that will carry a 240lb guy at 30mph, that's OK for you, and I don't knock it accept that you are breaking the law. And hell, I don't care about that either.

Re: Battery concern.

Yeah, not sure I 100% agree with that... Sure, high powered bikes will pull the same battery down a lot more than a low powered bike. That part I agree with. BUT, the cathode erosion occurs at an accelerated rate when high discharge rates are used. The cathode doesn't pop out and check whether you ...

Re: Battery concern.

The battery will work - but the problem is, you don't know if you're going to get 3 years or 3 months out of it. As another poster calculated, towards the end, you'll be pulling 2C. I've got some cells which I draw 10C from every day, and they've lasted years. I've got some cells that from the day ...
