I am constantly reminded of a slight variation on the square hole round peg type game when reading some of the visionary speculation regarding integration of batteries, EVs etc with the grid. Normally a straight forward puzzle and great cognitive development for infants but have you ever watched a child who has been given access to shapes that look more attractive than the correct ones but don't quite fit, with an added incentive of a brownie point if they do manage to fit them in. Good fun to start with but certain to ends in tears and tantrums.
Agree
Scruff - you have me paranoid about my Makita batteries. They look absolutely fine on the outside, sort of..... well, fit and forget. Are you telling me there is something fiendishly unknowable lurking inside?
Not at all, they're among the best in the business and the bigger the better in terms of longevity...double the price = 3 times the battery.
Samsung cells usually.
All I'm saying is if you stick a light bulb where a drill ought to be and forget about it, where the per cell voltage drops below ~2.6V they will never recover because they are electronically failsafed. You'll have to reflash the BMS to get it to play nice and most people can't.
This also means if you attempt recelling them then you have to maintain power from an external source to the BMS at all times and not let the smoke out with a conductive pokey jabber in the process.
They are state of the art batteries...if you're not in the habit of invalidating warranties you have nothing to worry about.
