What Has Been Done with Our Drive Systems!!
Jeff had a vision when he converted his 2005 Honda TRX450R quad from gas burning to electric, he wanted to "Design and build an electric quad using a stock frame while keeping the stock look", with a desire to keep the weigh under 400#. It certainly looks like he has hit the mark.
Frame
- 2005 Honda TRX450R, purchased from Kelly at KMS Performance (was previously a gasoline drag race quad) modified by Lonestar Racing
Motor/Controller
- Sealed HPEVS AC-35 controlled by Curtis Instruments 1238-7601 controller
Batteries
- Earth X Motorsports ETX48E X 9 = 120.6V capable of up to 1,000A burst, built in Battery Management System.
- Also, ETX12A x 1 for controls and LED lights.
- Two removable battery boxes, 65 lbs. total w/ tray
“ At the voltage and current above, the motor is ~76 hp which is good but 129 lb. ft. of torque at the motor! I have a 15 tooth front sprocket and a 70 tooth rear sprocket using 530 chain on a +14” swingarm. So the gear ratio is 4.7:1 so 606 lb. ft. at the axle = Diesel truck territory! ”
