It’s a pycarwings2 bug. In pycarwings2/responses.py it should make a change. line 661, in init

 else:
            if self.battery_remaining_amount == '':
                self.battery_percent = 0
            else:
                self.battery_percent = 100 * float(self.battery_remaining_amount) / 12

Where and how do I do that?
