Description
NASA-Clipper Battery Monitor BM-1 / black

Product details

The BM-1 is designed to monitor performance of 12 volt battery systems with capacities of up to 600 Amp hours. It is supplied complete with a precision 100 Amp shunt and a prefabricated cable assembly to enable simple installation. The unit continuously monitors voltage, current (charge or discharge), the battery‘s state of charge and the time to charge or discharge. This information leads to more efficient use of the battery, which can enhance the battery life and reduce the risk of failure.

Dimension: 110 x 110 x 27mm / compact version: 110 x 110 x 27 mm. Supply voltage: 8 - 16 Volts DC

Specifications:

  • supply voltage: 8 - 16 volts DC
  • supply current: 3 milliamps
  • battery capacities: 5 - 600 Amp Hour
  • load current: 100 Amps maximum 
  • charge current: 100 Amps maximum 
  • shunt: standard 50 millivolt / 100 amp 
  • displayed starter battery voltage

Can I extend the wiring? It’s 5 meters and need a few extra meter. If yes: witch size of cable and will it defect the monitor?

Hi Jesper, I would like to answer your question with "maybe" because I've never tried to prolong the harness but I imagine that it would be possible. There is only low current on the wires and for prolonging the harness I would take 1 or 1,5 mm² cable cross section. But first let's have a look on how shunt and display are working: Current flowing through the shunt creates a very small voltage drop there, which is proportional to the current height. This very small voltage is led via 2 wires to the display and there it is used for current measurement. If these two wires would be very long, there would be two risks. 1. A voltage drop but with 1 or 1,5 mm² wires that shouldn't be a problem. 2: Interference signals could be induced into the long measuring wires and lead to false display values. Some manufacturers minimize the risk of interfering signals by recommending the use of twisted pair wires. In the wiring diagram you will see at the shunt three: yellow, white and black. The black one is MINUS for the display, yellow and white are the two measuring wires. read the manual careful! There is a note which says: Black and white wires may only be combined at the battery-connection-side of the shunt and nowhere else. My advice: keep distance between the measuring wires and other cables or electrical stuff like powerful motors, pumps, etc.. I'm looking forward for your success report. Good Luck!

Quick delivery to my desk.Straight forward installation. Now the instruments tells exactly what is going on with my batteries. I have two set of batteries and one at the time is used for all use including starter. That schema should be added in the instructions.

Erfüllt voll meine Vorstellung. Mehr noch: entgegen der Beschreibung und der sehr guten Anleitung, kann dieses Gerät gleichzeitig die Spannung einer weiteren Batterie anzeigen. Dafür ist das orange Kabel. Aber eben nur die Spannung. Das reicht für eine Batterie die ansonsten nicht kontinuierlich ge-/entladen wird. In der Regel ist das die Starterbatterie. Die Bilanzierung der Lade-/Entladeströme erfolgt dann für die Verbrauchsbatterie. BM-1 ist einfach zu bedienen und ziemlich präzise.
