The battery meter is stuck at 100%, even after an hour or so of use. The last time I charged it, it dropped suddenly to 84% after only a few minutes.

Is there a fix?

Hi Bill D, the battery displays 100% at 4V but if you charge it for more it can go up to 4.2 volts. Thats why you see 100% from 4.2V to 4.0V then you will start seeing the drop.

That makes sense. Does the unit have overcharge protection or do you need to check the meter while it's charging?

Yes it will stop charging when full and displays Battery Level 100% instead of Charging...
