Review on 📺 7 Inch LCD Screen Monitor with Dual Receivers - FPV Monitor for Drone Quadcopter, 5.8GHz, 40 Channels, Automatic Antenna Switching by Will Micheals

For drone camera monitor. Provides a clear image at a good distance (I ended up buying a 3rd party high gain antenna). The controls and settings were pretty basic. The internal battery only lasts 1/2 hour (at 50% brightness setting). It's been 4 months, never discharged, charged, frozen or baked. The case must be separated and the motherboard removed to access the battery and its connector for replacement. I suspect they're getting pretty old for a production date like I'm seeing in video reviews from 2015. I'm currently looking for a new battery (2 Lipo cells, approx. 91mm x 35mm x 10mm at 8.2 volts right after the USB charger. Mine doesn't have a label saying the nominal capacity. There are a few millimetres margin in total directions.)
