Okay I finally have somewhat of an understanding as a beginner and got to "sink my feet" in a little bit today. Some of the process to me of an EV are pretty simple..........
(then again it depends on what you are working on like a scooter for example),
but grasping some of the things that I did I had to get the hang of it.
So I got to work on a scooter with a friend of mine who guided me through the experience,
and found it is something I actually enjoy.
We are waiting on two more batteries to be able to hook the rest of them up together.

Well, when I'm not reading the daily soap opera posts (and participating from time to time!) over on the message boards I have made some progress with the CB-750. At the moment the new front runner is a 96V system, based on 55Ah UB12550's and an ADC MT2113.

Here's the original 72V graph, followed by the new 96V graph:

Oh, just a couple of pictures from a few months back

A wiring diagram of my battery pack. All wires are within an 1/8" of each other, 2 parallel, 2 series. Buddy paired, wires to and from pack balanced.

And a photogragh of the wiring, disorganized?, nah, just effective.

OK, so I found a round tuit down the back of the sofa and decided to use it for calculating some numbers for my CB750 conversion. I've created a spreadsheet based off of Bob Brant's Build Your Own Electric Vehicle and John Bidwell's Secrets of El-Ninja. I used BYOEV for the required torque formulas, and I used El-Ninja for the available torque formulas (they were presented as a nice short list in the Bidwell book!).

Well, Folks
I been complaining a lot, so I finally buckled down, had a sheet of stainless steel. Got out the jig saw, cut me out a fender. Mounted my lights to it. Will probably go with one light, just put a better bulb in. That's for the future. A little clean up on the wiring too.

A big thank you to Jason and Jennifer! I picked up Jennifer's 1973 CB-750 this weekend - after a decade of no use they decided it was time to say goodbye. I promised to ride it back under electric power - but not for a while yet!

Dang. The Lectra is still so close I can taste it.. but... The two major pieces left before it could be taken on the street is a) wiring the manual on-off switch I mentioned before, and b) getting the lights to work. I got the switch and am pondering choices on mounting it on the bike. But today I wanted to get into the lighting system.

In another forum posting I mentioned a problem with the solenoid/contactor on my Lectra. The ratings on the contactor is 60v @ 300A continuous. I'd thought that would be sufficient for a 60 volt pack going through a 400A controller. But the solenoid is stuck in the ON position all the time, indicating the contacts have welded shut.

Ya,

Oh ya, jdh just had to be first, well his mower is battery powered, more fancy than tis ole tiller. I say, no middleman, get da power from the source.

The two 36V 20Ah battery packs arrived yesterday. Pretty fast shipping, considering they shipped from China on Thursday. (sunglasses in the photo are for scale) Sam at YESA was able to have them configured two different ways so I can fit one (barely) where the gas tank was and the flatter one in the left cowl. I think I'll separate the BMS circuit boards and put them in the gas tank area where they're better shielded from the weather.
