I've been playing with 25.9V and 33.3V battery packs.
Cheap controller upgrade allows 24 - 36V battery usage.
Rack holds 2 packs, so I can run at 25.9V and reaching back, switch to 33.3V for a nice torque and speed increase.
Got me thinking about other options ...
1. Why not build a light 3s pack in 2nd eZip battery case. (RC LiPo or Dell LiPo or laptop Li-ion)
I have a few 3s WinForce 5700mAh and 4 in parallel would give me 22.8Ah.
I could rig in series with 25.9V for a 10s 37V Turbo pack.
Switch position I (1) would run as 25.9V (485w motor output) for a legal 20mph ...
Switch to position II (2) would engage 37V (675w motor output) for nearing 30mph!
(675w output could push a "Racing Bike Tuck" to 30mph ... but more liable to add pedal assist)
Hook 3s pack neg to 7s pack positive then hook 7s pos to switch position I and 3s pos to switch position II.
or
2. Move switch and wires near seat.
This allows enough extra room in rack for a 5.7Ah 3s RC Lipo = a few miles of Stealth Turbo!
eZip motor@37V w/11T or 16T mod gives some assist to 34+mph.
I also like the idea of the 3s pack for 12V devices and 110V AC inverter use! Use charging port for 12V output.
36-37V operation advises a limited current controller ... <30A? Or throttle restraint at lower speeds.
