It needs more information on technical specifications of motor, controller and battery. (take ping's battery measurement parameters and use them so we can make an informed choice)
I spent days having to research options on max amps of internal controller and external controller - what the real expected wattage output of the motor actually is and a whole host of other things that are just not on your website. Granted it's far better than ebay sellers who just state 1000w motor, controller, etc.
for example, I have ordered a MP with external controller but I have absolutely no idea which model of controller I'm going to get with the kit. I get the feeling that I get a either 50A or 16A controller or somwhere vaugely in between.
This is a massive implication because it affects everything.
it needs more info for technical people - and an explanation of what AMPS, voltage, watts for newbies actually means and how it affects performance of a MP would be great. - use some of the information in here for a start:
