@goatman Great tests! Did you test the temperatures with the PlastiDip or without it? Also, what do you think about covering the vent holes on the positive terminal with PlastiDip? Is this not something to worry about?
where i live im more worried about keeping my batteries warm, my 25r packs ive been using for a year with plastidip. never had a overheat heat problem running at 7 or 10 amps
covering the vent holes
if you see my battery tests like the 40T or p42a, mnke 26650, those were done with the magnets and plastidip at temps of 102F to 104f
i use samsung 30Q and 25R, if i youtube people shorting out their cells, i dont see them blowing up like the mnke 26650 does
anytime ive had a p-group go bad, my battery just stopped working
no fire, no venting, no signs of anything except a p-group at 0 volts
cut the 2 inch slug tape 12 inches long and then cut it into 2-1 inch wide strips
that did 1 side of the battery with 5mm magnets
im using salvaged cells and wasnt all that happy about using the flat square magnets, but if i push on each of the 4 corners of the magnet and if i see the copper with the black mark, move
then i know the magnet isnt sitting flat and only has 3 corners touching instead of 4
its really teetering on 2 points with 3 points touching
in the picture above youll see the magnets arent completely inline, thats why.
i wanted to make sure there was a solid connection
the 4mm nickelstrip came in
grabbed how many i needed and put them on a stack of magnets to see how magnetic they became before putting them on the pack, didnt notice anything really
they do stick to the magnets really well though
nice low profile
