Ive been following the battery industry as Im making an EV and not overjoyed on prices of these things here either.

eg. 200amp hour sealed battery 64lbs - 196U$
same as above but bigger size same power - 560AU average

225ahr HD non sealed Lead acid $74 here $240 cheapest

Electric motors 1500U$ here 2600AU$

These things are heavier so I understand but the double for batteries is a joke when shipping in containers is dirt cheap for quantity.

Local prices on Harley parts are a joke, luckily I dont have the inclination to own one but my friends do and basically waste their money even on US sourced parts.

These are datsuns so if Autopro have better prices then at least we have an option. Also try Tuten Auto on Lygon Street Brunswich they beat everyones prices usually and source most things from Malaysia. The owner Tuck could do better with some basic social and manners skills to step up from the dark ages.
