If anyone is interested, the battery for a 70mai A800 or 70mai Pro and possibly the A800s, can be purchased from here -- https://vi.aliexpress.com/item/4000942106956.html?spm=a2g14.12057483.0.0.71bf1ec90hOp40
Does anyone know how to replace the battery ? Anyone have a video of doing it ? It seems my local dash cam supplier left out a lot when he said "remove two screws under the paper sticker and pull apart". The video for the 70mai Pro does not work.
WOW,that's amazing. Are there lots of batteries needed? There is a piece of good news: our official store will sell the battery seperately in the near future. Let's look forward it.
