I found the original factory specs of the Vectrix battery supplier a couple years ago and I believe that the max continuous discharge was in the 60-80 Amp range. Originally the Vectrix was designed to have a top speed of about 55 MPH and was already stretching the limit of battery discharge by 2x max draw. But Product Management for the Vectrix wanted to market the scooter as Freeway capable (which it already technically was with that speed) and insisted that engineering push the top speed as high as battery voltage and controller current would allow. They ended up with a 67 MPH top speed but had to push the electronics to even beyond the main fuse rating (popping the main fuse of I believe 200A, is not uncommon on the Vectrix and many DiY owners have gone through the labor intensive task of getting the controller out to reach the fuse and replace/upgrade it) and pushing the max discharge to 3x max battery rating. Obviously that caused a short life on many NiMH packs, most owners have found that their packs were losing cells early. I have rebuilt several NiMH packs that had lost one or more cells for such owners. So – it was not originally designed to do the current specified 67MPH top speed. It can reach and maintain it, but needs a pack and main fuse update. The charger had unrelated issues, so usually that will often need to be upgraded/replaced as well. The rest of the bike is pretty solid. Best to get one that already has upgraded charger and just put in Leaf cells and a simple BMS. Regards, Cor.

I have heard that using Leaf cells works well for this. Lots available out there given Leaf's issues with battery life. I had heard that the original batteries were driven rather hard, but 3X max? What were they thinking! Thank you.
