       Feel like a naughty school child.Don't want to tell @mntmn that I appear to have killed a Charger v2 board... 😬Back to bypass until I get home.

       @mntmn Not entirely sure.  Left it on my desk charging yesterday (powered off while working on desktop), plonked it in bag, pulled it out of bag today at Hackspace, no life.Thought it odd, toggled standby switch a few times, checked all the connectors, no life on battery or when attached to external power.  Recognized that symptom.Bypass charger board, life again.Enough to carry on with printer builds for today.Can't see any physical damage on charger board.I'm giving some side eye to the Oneplus phone charger sat on that desk and wondering if it's possibly played a role in the death of two boards.

       @kianryan hm, very strange. i guess you did try detaching and reattaching the batteries to the charger board to reset it? also, could it be that a cell is dead, could you measure them?

       @mntmnOne cell is measuring 3.6V, the other cell is measuring (and I've checked) 0.1mV. It's super dead.They're not your cells, they're a set of the high capacity ones that were linked to on the forum. Been using them for a while. But it was in use two days ago and I'm pretty sure it was displaying balanced voltage levels before charging yesterday.Will switch back to the original ones for now. Slightly concerned about that TBH.

       @kianryan perhaps the cells built in safety got tripped (which i hope it has)
