Things are still moving slow, of course, but they are moving forward!
My dad bought a new set of golf cart batteries for the GE garden tractor and my plan was to put them in my motorcycle for a few hours before they get put in the garden tractor, but I of course have to fit that in to the free time I have, so my plan is to put those brand new batteries in and see how the motorcycle performs, as it is I have around 20mph off road top speed with 8 year old batteries, the speed controller cuts out at 30v and 300 amps, I've seen the batteries drop down to 32v (with 42v in batteries hooked up) and 280amps, so right on the threshold of what the controller is programmed to cut out at.
Now for the fun part, lithium batteries, so far I have 3 packs of GBS batteries, 36v and 100 amp hours and two contacts that I might be able to get a 4th set from to make a 48v 100amp hour pack! I also of course need to get a battery management system and a charger but the battery source I have also gets bulk orders of those, so depending on how much work I have in the coming weeks I might be getting all those nifty parts before the snow flies.
The other fun part is a $250 Honda CX500 that I bought because it has a bad water pump, extremely common problem with these motorcycles, it also came with all of the parts to fix the water pump, it otherwise looks perfect with good tires, turn signals, brakes, seat and gas tank, a quick search on Ebay seems to show that if I sell off all off the gasoline related part that I need to pull off I can make around $500 back, making a $1,500 or less out of pocket cost look very practical if you use lead acid batteries and around $3,500 with lithium batteries.
