This is the ME-BMK battery monitor kit by Magnum. The ME-BMK is a single battery bank amp-hour meter that monitors and provides important information about the condition of the battery. This information will let you know how much energy you have available, and let you plan your electrical usage to ensure the battery is not being over-discharged.
The ME-BMK is easy to install and is designed to be networked with a Magnum Energy inverter/charger using a remote (ME-RC50 or ME-ARC50) or router (ME-RTR) to display information about your battery bank.
