heck to see if the problem always occurs with the same battery. Mark your batteries so you can tell them apart. Could be a bad battery or I had one battery where the little chip in the battery went bad and it would refuse to charge.

Yesterday same thing, 17th or 18th hole I got the cutout. This was rapid drilling one after the other. Let the drill sit for 15 minutes and drilled another 6. Fished those without a hint of success and gave up for the day.
Good suggestion and I’ll mark the batteries. My hunch is that won’t matter. They are charging fine and overall capacity in inches of ice drilled seems good. Rain today so maybe tomorrow.
It’s pretty rare for me to drill more than 10 holes in one push but would really like the option. Now I”m wondering if I need to keep my gas auger for high volume outings:???:
