Attempting to charge LiPo or even Nimh with a lead acid charger is likely to require a fire extinguisher, or even an ambulance.
Yup, the flashlight has a builtin charger circuit, I'd like to use that if possible.

It's an LED flashlight, I find it very practical for playing pretend-mechanic.

And that's why I'm asking here. Don't want to burn down my new garage.
