I just scored a bad pak from a guy doing work here. It has the bad chip that tells the charger this battery is no good. So I think I should end up with 8 or 9 good Sony SE US18650VT cells according to google searches.
Score!!!
I have a few high current Samsung cells from a ryobi pack that had the same issue. Free is my favourite price
Nice! Have fun taking it apart. :)
I bought a ko bl1830. It lasted ~1 1/2 years before the charger red flagged it. When I opened it up none of the intermediate connections pcb were made. The failure was due to a spot weld coming loose on one cell. The other nine cells tested above 3V.
Yeah gettin the pack open was the hardest part .. lots of patience and some really small sharp snips ..I cut right around the screws
I should be able to get it open fairly easily - will update as I go
The knock off just had torx with no security pin. The cells are Golden Dragon.
woohoo got 10 good batteries out of the thing all at 4 volts +
They are green
SE US18650V
willing to trade some if someone is interested…
need a good single cell thrower
