Thanks for your interest guys. Currently with only half the batteries fitted it is a 10p 10s array. When I add the tank battery this will be in parallel so voltage remains 38V or so. Motor current limit is 200A to be increased to 300A with the extra batteries. I was hoping for 60 mile range and 60 m...

Honda H100 project

Here are some details on my electric motor cycle conversion.

Alternative to Thunder Sky LCP

With the increased cost and difficulty in obtaining the Thunder Sky LCPs I have been looking at alternatives. Other Chinese LiFePO4 being the obvious one but also a parallel approach of polymer cells. The poly cells perform very well but are still expensive. The links show pictures of a 100Ah cell u...
