The wire, if I get all the strands out, which I seldom do, is probably 16 or 18 gauge. It was meant to carry ac current. Actually I was thinking about copper foil like they use in jewelry next.
I soldier but I really don't want to. They tell me the heat might effect the batteries If I get them too hot. What do you know about the conductive glue being sold these days.
I am still working out the details for the actually ah of the nimh batteries from china. Heck they are all from china. Probably coming out the back door of the same factory that makes them for the american name brand labels to go on.
The best deals are from china on the aa 3000 mh if you can survive the shipping from china, which has been a nightmare during the Christmas season. I build in 90 cells units then string the units together. Those are AA but I also built with 30 C cells mfg rating is 9.5.
I THINK the true ah is about 4ah per unit and the volts are about 36. It's a learning experience. More a process than an experience. I built the AA and C packs to be about the same AH so they are about equal in the draw more or less.
The c rating is strange but it will turn the wheels with any amp battery and not over heat. If there is no resistance that is, but the speed of the wheel is definitely linked to the Amps in the battery. So I'm not sure what the C rating is.
The scooter I built is much lighter and the hub is probably a few watts less, so it ran pretty well yesterday on the battery. It was so cold I had to come in before I got any decent test for range. It did pull some significant hills though slowly of course.
The plan is to jack up the ah one last time over the next few weeks. It will go up by four or five with the next string. then I have another string coming in from China on the slow boat.
When I am able to get this thing on the road consistently, I will have to begin working on the charging system. Since I can not ride it with any consistency, I am charging the pack with two lead acid chargers. Some of the time giving it 3amps at a time. Then after what I think is about the right time, I cut the charge down to one and a half amps for a while. I have a shutoff timer switch I built so I run them one hour at a time.
The weather is too bad to work on the scooter very much but I think it is close to operational. Well it is good for testing I think.
