Turbo Switch Wiring Diagram
Center switch position is a disconnect
(Faulty switch could result in short condition! (unlikely but) Do not operate unless both batteries have proper fuse installed!!!
Simply redirecting 2nd battery (3s 11.1V) neg wire allows a turbo function.
Normal - my eZip, 25.9V provides 17mph w/485w motor output.
Turbo - my eZip, 37V provides ~23mph w/695w motor output.
Upgraded to 16T wheel sprocket or 11T motor sprocket
Normal - my eZip, 25.9V provides 20mph w/485w motor output.
Turbo - my eZip, 37V provides ~27mph w/695w motor output.
Any Turbo voltage is possible ... if controller supports normal and Turbo voltages.
eZip MY1018z and XYD-16 motors have survived as high as 48V input if ...
lower Amp controller or stringent throttle restraint at lower speeds.
35A 48V can "burn up" motor and\or shear the sprocket retention key.
I chose 7s (25.9V) plus 3s (11.1V) because I run 25.9V at gearing for legal 20mph.
I have a large quantity of 3s LiPo that can fit nicely in 2nd eZip battery case.
(Can also task 11.1V pack for 12V lighting or inverter use)
Motor has been proven at 25.9V (20,000+ miles on 3 eBikes) and 37V (4000+ miles on 1 eBike)
(27mph motor only allows 30mph capability w\heavy pedal assist!)
