Battery in TC model year 2020 shows 61.2V with voltmeter;  divided by 17 is 3.6V pr cell.

Remaining shows 33%. Original battery. What type of battery cells?

I'v thought from reading somewhere that the cells are 2500mAh, but then remaning percentage would be may between 2% and 22%.

According to the table shown here it's more like above 3100mAh cells.

Anyone knows the type of battery or got the right discharge table?
