Re: Lithium PANASONIC CR123 Explosion
While unregulated lights draw less current from the batteries
as the batteries get weaker (because the light gets dimmer)
regulated lights hit the batteries harder the weaker they get. To pull the same
power out at a lower voltage requires more and more current.
When the batteries have almost nothing left, and are at greatest risk of being
reverse-charged is when the regulator is pulling the maximum current.
Perhaps the regulation circuitry tries too hard.
