First post.
I've learnt a lot from this board, I'm trying to find a solution to the following. There's a vast amount of knowledge here, and I'm hoping I can find a solution to the following. I'm building an electric scooter (vespa type), not to ride on public roads, purely to demonstrate the aggresive nature of electric acceleration. My strength is design and fabrication and my weakness is an understanding of volts, amps and watts. I'm at the point where I'm designing battery/controller compartments and I need help. I want this thing to be able to accelarate hard. Top speed isn't that important to me, 70KPH is fine. Range also isn't an issue, 20 minutes of run time is all I really need. Of course my top priority is weight. From a design standpoint, I need a 12" rear hub motor that runs a 130/70/12 tire, I can't really deviate from that. Right now, I'm looking at an 72v 8000w QS260 12" V4 hub, with an 72v 8000w ND72850 controller. My question is what type of battery design would be best to accomplish my goal? Everyone seems to be looking for top speed and range, I'm not. Torquey acceleration is what I need. Batteries get very heavy when range and 120KPH are needed. What I'm looking for may not be possible, but I'll be damned if I give up without giving it my best. Cheers to all who offer any advice.
