Vehicle1969 Honda CT90
This is the third version of this motorcycle. The first used a 12v Ford starter motor and resister wire & contacts for a controller. It had one big FLA 12v battery. The second used a Scott 24vdc motor and used two 33ah Hawker Odyssey Batteries with a Curtis 24v - 36v controller. This final version uses an Etek Motor with three 33ah AGM sealed 12v batteries and the same 275a Curtis controller.
I now am using 12 Thunder Sky 40ah lithium batteries.
