I purchased a used and working pint x with 100 miles on it, now it has 325 miles (and still works great)

I wanted to make sure the known early model pint x battery flaw wouldn't be an issue. (And I wanted to clean, inspect, and get a feel for how it all goes together)

Anyone have any strong opinions about that solder joint, zoomed in on the second picture?

The board works great, and I didn't see anything terrible that would have me questioning its safety... At least not immediately. I don't know much about soldering, but I know enough to know it looks less than perfect.

Should I be planning on fully removing that board (bms?) and cleaning it in the (not too distant) future? I feel comfortable soldering LED lights, but this one would be well beyond me if it needs reworked.

Thanks all!
