Other Notes: Resistive setup for 12 volt rear/36 volt front light. Lull lift battery guage. 3.5 to 1 ratio to lower top speed and increase torque. Hi/low switch to limit speed to 20 and help battery life. Max Kw limited by battery sag. Update.. batteries still holding well, but seems to discharge a little faster, batteries have held up longer than expected for the abuse :) Update 2-11-12 Battery capacity down to about half capacity, looks like 5 years is life of batteries. Upgrade to lithium in the future, batteries arrived 1/14
