For some reason my solix shuts off and restarts randomly when I go to crank my motor. I replaced the crank battery with a new one and still having the issues. Sometimes it will crank and not turn off but its hit or miss, it doenst make any sense. Also I have a helix 12 at the bow and it doesn't do that ever.
Here is what I have if it helps
4 batteries
3 for Ulterra 36v
1 for motor, helix 12, solix 15
