I would like to ensure my battery and circuit design are properly sized to drive the whole string of red LEDs, PRT-14503.

They are listed as running at 3 V. If you know their current draw or wattage, I’d appreciate learning that so I can finish my design and order everything I need in one go.

Thanks!

The manufacturer doesn’t provide that, but one could safely assume that because it uses two CR2032 https://www.amazon.com/AmazonBasics-CR2 … B0787K2XWZ which show 225mAh, so they appear to run @ ~450mAh, though it is still a better practice to determine this experimentally, and adjust.

Hope this helps!
