ME-BMK Battery Monitor

To ensure your batteries perform satisfactorily and have a long life, they need to be properly maintained and charged. If you're using a Magnum Energy ME, MS, MS-AE or RD inverter, monitoring your battery bank is easy with Magnum Energy's Battery Monitor Kit (ME-BMK). This kit acts as a “fuel gauge” for your batteries, monitoring their state of charge (SOC) and then providing this information in an easy-to-understand display via the ME-RC remote. With accurate SOC readings, you can avoid unnecessary battery recharging, saving on fuel and long-term maintenance costs.

There are several other monitoring devices on the market that measure different aspects of a battery bank. The DC Voltmeter measures Open Circuit Voltage. It is not completely accurate and requires the batteries be at “rest” when in use. A hydrometer is another device that measure the concentration of battery electrolyte in each individual cell and compare the readings with the OCV values from the battery manufactures. An amp-hour meter is an electronic measuring device that uses a precision shunt to calculate the amp-hours going in (charging) and coming out (discharging) a battery. This meter tracks the amp-hour usage and compares it against the amp-hour capacity of the battery to determine its charge condition.

The Magnum Energy Battery Monitor actually combines the advantages of these devices with additional information such as monitoring battery temperature and calculating battery efficiencies to provide an easy and accurate means to determine the battery’s State of Charge (SOC) condition. BMK requires 2 Amp DC fuse from any autopart store.

*Many products will require the use of a direct shipping quote from one of our CSR agents due to new DIM weights and measure changes as of Jan 10th, 2018 from major carriers.

Packages greater than a square cubic foot are now required to use a “volumetric weight” based upon length, width, height of a package from most carriers which alters actual weights. Oversized / Unique shaped packages are most affected and may not apply to your specific purchase(s). However, IN ORDER to save you, the customer, shipping costs, associated fees, and to keep product costs down, we are taking action to give direct shipping quotes based upon delivery methods available. Your full name and email address, required in the checkout, is so we can offer you a shipping quote. Your item(s) will NOT ship without communication from our CSR agents. We apologize for any inconveniences.*
