I didn't Know This Was Possible!! Backdoor Battery Access to the Anker SOLIX F3800!

Published at : 23 Dec 2025

In this video I experiment with charging the Anker SOLIX F3800 via the expansion battery port to see what happens. I got inspiration from @NoiseLab47 when I watched his two videos on the topic. Super interesting results!

**WARNING...this can damage your power station and void your warranty....I was just experimenting in this video so continue at your own risk!**

Inspiration for this project came from @NoiseLab47 . You can find @NoiseLab47 Anker F3800 Videos HERE:

I'm sure there are plenty of other videos on YouTube doing similar experiments but this was my main inspiration. Thanks NoiseLab!
