You would, of course have reduced range and probably speed, however it shouldn't ruin it.
As for checking the voltage, I'm a big advocate of the Cycle Analyst from ebikes.ca. It allows you to keep close tabs of your battery at all times with a wealth of information and is worth it's weight in gold. IMHO.
Actually this is correct, in that one should not use a battery that is not brought up to a full charge before being disconnected from the charger. And the BionX panel is more than sufficient for battery monitoring in combination with the LED indicators on the battery.
