I had a really close call in stock. As you might know, there's that annoying bug, where battery recharging never switches off if it was damaged even the slightest bit.
I was rebased to Australia, and I was unaware of this bug. I spent 99% of the trip switching between battery and diesel propulsion and barely made it (the last couple miles were purely on batteries).
After that I learned about the bug, and I kept a close eye on the damn thing. then I instaleld TMO and the bug dissapeared.
