My minolta A2 died on me last year. I have a pair of lithium ion rechargeable batteries and a charger for them. Each battery is 7.4V and 1500 mah.
I was wondering if I could cobble together something to use them to power a LED headlight or maybe a LED flashlight.
I am pretty handy and a good solderer.
It's probably more trouble than it's worth but the geek in me wants to try it anyway. Wouldn't cost me anything other than time.
Is this sufficient power to run a decent LED? Would I need to run them together in parallel to get a decent run time (3 hrs)?
