I ordered a Formentor e-hybrid (204hp) and am waiting for delivery.

Given that the battery has a gross capacity of 25kWh and a usable capacity of 20kWh, what is the best way to charge the battery?

Can I charge it to 100%, considering that the usable capacity is already 80% of the gross capacity? Or should I still only charge it up to 80%?

If I do that, in reality, I am only charging 65% of the battery.

Or is my thinking wrong?
