NASA Clipper BM-1 Battery Monitor

NASA Marine



Add to Cart


With this information you can stay on top of the state-of-charge of the battery bank, and ensure you are using it efficiently. There is a backlit LCD display and a visual alarm is triggered should the voltage fall to a preset level. The BM-1 has a low current consumption, so you do not need to worry about it draining the battery bank itself!

The BM-1 battery monitor comes complete with a precision 100 AMP current shunt and a prefabricated 5 metre cable assembly (fitted with a fuse, plus ring terminals for the shunt and battery) to enable simple DIY installation.

Available for both 12V and 24V battery systems - please see the options menu above.

The unit comes with a 'shunt' - a device that goes between the battery bank and all loads or charging sources, that enables the monitor to measure what is going into or out of the battery bank. Please see the wiring diagram for details of how it should be wired.
