Hi there, I have enjoyed using a Bluetti AC50s for a few years now, but I am finding the display to be somewhat erratic, partcularly the battery percentage indicator. I have just now powered it up through the AC brick in my home and the battery percentage is not showing up. Is there a way to make this display work again? Thanks!
Hi @Agrout, We would like to know if you haven’t used the AC50S for a period of time. Long-term non-use can cause excessive discharge. In this case, please use a car charger or solar charging, which helps wake up the deeply sleeping battery.
If you use solar charging, please choose solar panels with a voltage range of 12-40V.
Once the battery level returns to normal, you can proceed with AC charging.
If the car charger doesn’t help, I’m afraid you’ll need to contact customer service to arrange warranty service.
