Wow, that was fun.
Quick & dirty discharger that wouldn't discharge quickly turned into diagnosing the issue...no voltage on the charge lead, even after charging it, though the charger shows it must be connected properly. Well, drat, I'm pretty sure I know why that is...
As I thought would be a good idea, there's a diode on the other end of the charge lead. That's gonna make discharging a PITA.
Tiny alligator clips to the rescue!
Pretty janky!
Sigh. Suppose I'll have to make something safer if it's going to be a permanent fixture. A removable fuse in line with an alligator clip as a diode bypass, so I can just pull the fuse out when it's not needed. As if I have any 0.5 amp fuses laying around...
I wonder how many AH I should pull out of it each discharge...
It's a guessing game when you aren't working cell by cell.
BTW, a nylon bushing from a Doorman multi-pack will work, if modified. $5 vs buying a whole rod for $35.
