That was just the first once that I came across that could handle most ebike voltages. If you're not running a BMS (because your pack isn't lead), just watch out that it doesn't drop your battery voltage past it's lower limit; these things don't have a set low-voltage shut-off.

I doubt that it will be bothered by there being voltage on the output side when it isn't being powered. You can/probably should use a multi-meter and see if any current is flowing back in to it with it powered off. Don't want to find your main battery dead because this thing has been trickling it off slowly. Or just go with a diode and have some peace of mind on both counts.
