These people won't buy a $90 light, I'm not sure if they'll want to buy a $90 charger when with a little bit of brain (well if i use the light 2 hours and the batt's supposed to last 4 hours and it takes 10 hours to charge, i'll set my timer to 6 hours), a $5 charger can get you about 90% as much life. Then again, who am I to talk, with my fancy light & motion dual light.

Also, that probe is external, my battery pack has the cells encased inside half an inch of injected foam in a small bottle. The connector has 4 prongs, 1 of them is for the built in probe, should I wish to buy a smart charger.
