Can I ask about debugging/fixing a broken product?
I've taken a part a broken roomba down to the PCB. I can connect the PCB directly to the battery and connect the charging cable & charger to the PCB.

I'm wondering if I could post about asking for suggestions on debugging the issue. I know consumer electronics are most likely off topic, but I'd ask about the PCB specifically and why the input voltage is wrong. 

Someone suggested I try debugging the charging mosfets, but I'm a beginner hobbyist and don't know how.
