Baitboat Battery Meter Instructions The Baitboat Meter indicates the voltage of the boat battery and must be used with no motors running. The graph shows the profile of a fully charged battery from fully charged to fully discharched. The point on the meter where the green zone meets the red zone indicates a value of 11.7 Volts and corresponds to 40 minutes use of the boat. The green zone indicates from 13.2 to 11.7 Volts and the red zone from 11.7 to 10.2 Volts. An estimation of time remaining on the boat can be made from the meter e.g. if the meter needle indicates halfway through the green (12.45 Volts) the boat has about 23 minutes of life remaining. The boat should not be used when the needle is in the red zone. The included ‘Y' connector is used to monitor the battery condition whilst being charged from either the mains charger, the bankside or the solar charger.
