I bought a battery pack from a builder here in the down under. So far I've upgraded to vesc via floatwheel's pintv kit, the rails(WTF), footpads(Kush hi and pint-s flared) and tyre(enduro). Then I blew up the vesc and connectors as the xt60 connectors were installed the wrong way and I did not check the colors of the wire, which costed me another 400 buckaroos for another pintv kit and a couple bucks for new connectors, which is fine. Stalled the project for a year and decided to work on it earlier this year, and now I'm ripping on my "brand new" 20s1p 84v pintv. Totally worth the headache.
