On high some protected cells will either trip there protection or provide less currentā¦ ?
IIRC on the Prince mini, the RPP is implemented as a raised ring around the positive contact on the driver. The cell raised top has to reach inside to make contact whereas the flat negative end wouldnāt. Flat top cell donāt work. I think i had to use some KeepPowers or a magnet. Iāll check tomorrow. Not sure how it will work on the Tool AA.
Edit: i checked my Prince mini and it has the raised ring around the positive contact on the driver. I use KP protected 14500 800mAh (black w silver label) which are BT but the raised bit is not even tall enough and i need to add a thin round magnet to get it working. Obviously those protected cells do work - when you help them a bit.
If it works the same on the Tool AA, be prepared to fumble a bit with whatever 14500 youāve got. Only āvery raised topā cells will work as is.
