So I understand that one of the major functions of recup mode is to save the brake pads?

IMHO, the major benefit is making people believe they just saving the planet whilst "recup" is on...

It will maintain speed, if the hill is only gentle - and it gives you psychological support, when you running near capacity, but still with a long way home ahead.

There are reports, system will shutdown when reaching 10% battery. But even if you're above 10%, it's possible falling temporarily below threshold due to big charge e.g. steep uphill in power mode. In this case, just stop wait a few seconds, then restart your stromer.
