First of all the frame isnt in most cases up to the task.
2nd they use bicycle parts often from downhill bicycles but still not up to the task.

What wh/km where u at at 122km/h with flux weakening ? And what wh/km would you have with no flux weakening...

Re: 72V 3000W Cyclone Electric and Gas Generator Build (SBP kit) - Three Phase Dev

But when you count in the defective parts from your combustion engine in the next 10 years and the fuel and lubricating oil fro the next 5 years (about what and battery would last.) And what would it look like when you get to have a seized-up piston ? :bigthumb: get some quality flexible 100w solar ...

Re: 80% charge in one hour?

Thats only partly true.
Each Lithium chemistry has its own parameter for fast discharge and fast charge to yield a reasonable cycle life.
Watch in the specification of your buy. and only charge fast when needed.

Sure, but "Turnigy Graphene" is the product name i was refering to. And those are GREAT batteries. The best i'v...

The cells hold super well, they need like 5-10kg of pressure to get in.
But do the cells not want to expand and shrink while heating or cooling while in use.
It could cause great problems like popping open on top or buttom ?
