.....--- Rechargeable Batteries for Optivisor/Magnivisor---

=========================================

Being older and working in N Scale I bought an Optivisor, actually a Carson Optical Pro Series Magnivisor off Amazon. I like the interchangeable lenses and how easy it is to flip the lens up out of the way. It has a nice LED light but the downside was it is powered by 3 AAA batteries that don't seem to run it for too long before it starts to dim.

I got tired of the expense involved in replacing them so decided to power it with some 3.7 volt ex-drone batteries I had from my short drone experience. I also have a USB charger that will recharge them. Three AAA batteries are 4.5 volts in series when full of charge so wondered how the 3.7 battery would work. I works fine and the light is just as bright and lasts a long time between recharging the battery. I also have a number of these batteries so if one goes down in the middle of a project I just swap it out. I'll also use these batteries in two DCC wireless throttles I'll be building that were designed by Dave Bodnar.

The following pictures are pretty self-explanatory but email me if you have a question:
