Triple pole, no?

Just judging by the 6 wires coming from the motor, it has Hall effect sensors. You should be able to find a reversing combination for that motor using the ideas in this thread.

Adding to my list of places to visit before I die :) Might want to trim back that tree branch!

Great to see those modules working well without too much hassle. What's your long term balancing/BMS plan for them?

We agree now that this is salvage/junkyard stuff. It should be priced accordingly.

If I recall, they used those as shims to keep the battery from sliding around inside the box (for whatever that's worth).

If anyone's interested, I just received my 7s3p pack; it seems normal and tests OK on the voltmeter but I think overall it's more of a R&D effort than I'm up for to build a full size car pack. If you're in the US and want to buy it from me I'm happy to send pics; I promise to ship in a much...

I'll let you know how it goes ;) I figure it's the best way to get to know these batteries on a small scale first.

After watching "Deadwood", I wonder who really makes money in the 'Gold Rush'.

That sounds much more like the process I went through.

Well, then the job was easier than I thought. Regardless, the discussion set me on the right path, since I would otherwise have wondered why swapping the same two colored wires for motor and sensor didn't work.

Does that imply that the spreadsheet is incorrect? Your version would suggest there should be 3 valid forward-running combinations and 3 backward-running, since they are just rotations of one another.

Ah, likely true. Thanks.

Hrm, his original post is now missing, which doesn't help here. If you look at his truth table (attached), you see that certain motor combinations will *never* produce smooth running in either direction. "Runs good" motor wirings produce either good running or "NR" -- no rotation -- across all...

This thread was awesome. The spreadsheet in particular helped me find the reversal combination much faster -- if you use it as a "truth table", and cross out the rows and columns that won't get you to the right solution based on the results you get, you can reason your way to the right...
