I found this forum in a google search for other nuts like me who might have modded a Monster Moto E-1000. I saw OFFROADSCOOT's AWD build, and I just HAD to join and share in the fun!
So, This starts off with me seeing an electric mini bike at Home Depot just before Christmas last year. I couldn't get it off of my mind... the next time I visited Home Depot, they had one marked down to $199.00. Heck, I can't even buy a FRAME for that cheap, let alone a whole minibike, so I brought it home with me. I did need a little minibike for bringing along camping, and going to the mailbox and stuff.
I have a strange delusion that I could run the world on Ryobi tool batteries. So project one was to see if I could replace 50lbs. of batteries with something much lighter. I gutted one of those multi-chargers to get the battery mounts. I simply wired each pair of Ryobi batteries in series to get the 36 Volts, then wired the pairs together in parallel to get more amp hours. Plus, sharing the load across 4 batteries instead of just two is better for the cells. I definitely get more distance with 4 batteries than running off of 2 until the die, then plugging in another pair. I can get about 5-6 miles out of a set of 4AH batteries.
I was hoping I could get someone to give me suggestions on getting some more speed. I'd like to add another pair of batteries, to make 54 volts but I dont know if the stock controller can do that or not. If not, then I'd like a suggestion about what controller to get. I'm also open to suggestions about different sprockets, etc.
Thanks for any advice!
