18650 Battery Blank

This is a battery blank, so you can hook a battery pack up to a standard lithium battery charger.

I needed this to use my existing battery charger to diagnose which cells in a 10S pack were toast.

Just put a piece of nickel strip or wire through the slots on the battery blank, then hookup to it with alligator clips. Voila! Just make sure the polarity is in the right direction.
