Re: [EVDL] Lithium battery setpoints...

Excellent Lee, thanks. I am not arguing, just speculating - I bet if you tighten the first time until the resistance drops no more, then dis and re assemble the same joint again, tighten until the resistance stops dropping- you will get a different final resistance and a different final torque.

Re: [EVDL] Lithium battery setpoints...

In air, aluminum oxide forms nearly instantly. You have never seen pure aluminum, because it does not exist where a human can stay alive to view it. Therefore, sanding is a useless activity, if the goal is to remove aluminum oxide. You can do it, but you can't stop it from reforming. I suppose

Copper oxide is a semi-conductor. It basically conducts electricity pretty well, which is why copper electrical joints don't need any special treatment (as opposed to aluminum.) http://www.jstor.org/stable/99170 Bill D. At 03:05 PM 7/30/2014, you wrote: Remember iron oxide, aluminum oxide, c

Re: [EVDL] Lithium battery setpoints...

Almost forgot. If you didn't lightly sand the cell terminals and coat with thin film of NoAlOx, then you need to do that now. Yes, doing this is a pain in the butt, especally after it is all put together, but it must be done to get good, low-resistance, reliable, connections on the cell termin

Re: [EVDL] Lithium battery setpoints...

Definitely allow the pack to balance for awhile. Particularly fresh from the factory. Check them all with a voltmeter, not just with the BMS. You want to be sure that everything is connected right and is working 100% properly. Trust, but verify. Do this before and after the first few test runs.

Re: [EVDL] Lithium battery setpoints...

Hello Zeke You must first make sure cells are well in balance by some sort of equalization procedure which involve shunting current from higher voltage cells to the others. Charger is cutoff when a cell reaches above a max set voltage, like 3,65V for example on my Ranger EV. Does your BMS mon
