Under-voltage protection

In order to prevent a sudden loss in power, the controller will begin to linearly ramp down the
current limit, once the average battery voltage falls below a pre-set under-voltage start level. The
current will be ramped down to 0 and a 7 flash fault indicated if the averaged battery voltage falls
below the under-voltage cut-out level.
