Running firmware 0.3.3 and software 0.3.0.
Charging the battery voltage of 3.552 is 98%. Discharging 98% is 3.171 and 3.183. Reset mcu and did a charge cycle and started discharge and still not tracking Battery level correctly.
Charging is just as bad. 32% level listed at 3.992 v. Will hook up external volt meter to battery to determine if the battery voltage reading is bad. Just jumped from 33% at 4.2 volts to 100% at 4.201 volts. Understand now why the max charge was originally set to 85%.
Found that I didn’t have a lithium with the 3.7 v specification. I got one and ran discharge and charge cycles and now it doesn’t seem to lock up or jump on the battery level percentage. The Battery health didn’t reset with a new battery. Below is a percentage vs voltage and current of battery.

Hi,
When a new battery is installed, it can sometimes take a long time for the HAT to detect battery health and level. In some cases, it gives correct values after the battery has been discharged/charged once.
