Electric Bike Batteries - Why You Shouldn't Completely Discharge Them
To prevent you from over draining your battery you can add or buy a battery pack that has a LVC or low voltage cutoff
. A wire connects from the battery pack to the motor controller and if the voltage of any one of the battery cells drops below a preset voltage, the LVC will trip and cut off the power to the controller stopping the bike. Once the voltage rises the power is restored and the bike will move again. A LVC is a great safety device and will guarantee you never accidently over discharge your battery pack. I hope this helps you understand why you should never completely drain your battery pack.
