I have a question about the tinyscreen+. How long would a tinyscreen+ run on full power with a fully charged Lipo 150mAh battery attached? I also have the same question, but for a fully charged Lipo 500 mAh battery, how long would the tinyscreen+ last? Thank you for reading!

Depending on what is displayed, the TinyScreen+ can draw 30-60mA. So, about 3 hours on the 150mAh battery, and about 10 hours on a 500mAh battery. It's usually used with our 270mAh battery for about 5 hours of use.
