Abstract
The invention continuously monitors the current drawn from the on board battery system of a recreational vehicle or marine vessel. The device calculates and displays the energy remaining as a portion of the total capacity by accumulating over time the net energy drawn out of the battery. The device accurately accounts for the known effect of effectively lower battery capacities at higher current draws, and also allows the user to re-initialize the battery system capacity to reflect either degradation of the battery capacity with time or upgrades to the battery system.
