9 month Battery & BMS Stress test. High voltage drop in the JK-Battery? +How to test solar strings

I used the perfect 100A charge current to test the battery and BMS with a little stress test. This is pretty much the maximum current I have designed the battery banks for. So, let's run this through the #Heltec, the #JK and the #Overkill BM one after another and see if we can find any problems. Yes, we did actually!
In a second test I want to check on the Big Shed solar string installation and find out if all 4 strings perform as expected. I'm showing you how to check your solar parallel strings and find issues.
