The BMV-700 is a high precision battery monitor which displays voltage and amperage. It also tracks battery efficiency, average discharge, amount of cycles, and more. The essential function of a battery monitor is to calculate ampere hours consumed and the state of charge of a battery. Ampere hours consumed are calculated by integrating the current flowing in or out of the battery. The BMV-700 is a great addition to your lithium battery purchase!
