Hi all, just a quick update:

Found out the motor is series wound, and is worth $1300 refurbished (we got ours for $100)

RE: batteries and budget

We found free batteries. Maybe. A guy (legend) in Perth has several hundred nicd 1.2V 40ah cells to give away - from an old aviation company, barely used. This is great because they have an incredibly long service life and are quite difficult to ruin. Apparently. But they're free which is great. We just have to pay a couple hundred in shipping, bringing our total spend to $600 and leaving $400 for the rest of the build.

We're looking at running a higher voltage now, a 72V or 96V should get us the range we need, or two 72v packs in parallel. my best estimates for a 72V 40aho pack are between 20-30km range.

But I shouldn't count my chickens before they hatch.

Anyway, progress being made and coming in under budget is far more likely with this development. Sweet.
