The Victron BMV-712 Bluetooth Smart Gauge uses a sophisticated algorithm to keep track of your battery bank's state of charge, voltage, amp hours consumed, time remaining, and much more. This information is all displayed on the gauge itself but it also comes with a handy iPhone app to show data on your phone via Bluetooth. We highly recommend adding this kit onto any lithium battery purchase.
