Wrong battery voltage reported

Post by karlelch » Sat Jan 13, 2018 3:20 pm

Hi,

I am getting high voltage readings like 4.3 V or sometimes even higher from the PIco (see below).
When I measure the voltage at the battery, it reads 4.067 V (for the firmware reporting 4.3 V). I am worried that the PIco might try to charge the battery beyond the recommended voltage. I am using a 3000 mAh Lion battery (LP603048-3P, 3.7 V), which I bought some time ago as a higher capacity battery for the PIco (it was advertised to be compatible with the UPS PIco HV3.0A).

Please advise.

Best
Thomas
