Masterlink BTM-III Battery Monitor

Monitor up to 3 battery banks for a single display.

Keep track of vital battery bank information from one convenient display. The Masterlink BTM-III battery monitor gathers voltage, current, Ah, time remaining and remaining capacity (in percentage terms) data for up to 3 battery banks. The information can be displayed in a number of different ways. Users can select to have all three battery levels displayed on a single screen or elect to page through each bank and have more specific battery information. Additional LEDs indicators offer a simple and quick to read visual display of battery level. The well-lit LCD screen also displays historical information.

In a system with only two battery banks the input of the third bank can be used as a backlight input. If you connect this with the navigational lights, for example, both will turn on simultaneously. The BTM-3 includes ten languages: English, French, German, Spanish, Italian, Dutch, Norwegian, Danish, Swedish and Finnish.

This panel is suitable for MasterVision, Mastervolt’s modular central switchboard with various monitoring functions. The included shunt, a measurement device for accurate reading of on board systems and batteries, should be placed close to the battery. For a high current system an optional 1000A Shunt is available.
