Title: non-train-related LED question
Post by: faithie999 on December 21, 2018, 07:37:52 AM

I made an ugly Christmas sweater adorned with a couple of strings of tiny LED's that I purchased at Walmart.  the strings are powered by 3 AA batteries wired in series.  the battery pack is inside the back of the sweater at my waist and is always in the way when I sit down (yes, that is definitely a first-world problem!).

will 6 volts from 2 CR2032's in series overpower the LED's?  alternately, would a single 2032 (or 2 in parallel for more run time) be enough power?

I don't want to cut into the wiring until I know what source I will use.

thanks!!

2032 isn't going to work for you. A 2032 has a drain measured in micro amperes. You need milli amperes. Even if the drain were sufficient, a 2032 battery has but 1/10th the reserve of a single AA lithium battery.

Move the battery pack to somewhere more comfortable.
