The Nasa Marine BM-1 (BT) Bluetooth Battery Monitor is a great solution if you don't have the space for a display, or routing the cables would be a long job! This battery monitor directly monitors your boat or caravans lead-acid batteries and sends the data, wirelessly by Bluetooth, straight to your mobile phone or tablet.

Using a simple Android app, which is freely available from the website or Google Play Store (requiring Android V4.3 or later), you can see your service battery voltage, the amount of current flowing in or out, the level of charge for the battery and whether it is time to recharge or discharge the batter. If the battery level gets dangerously low an audible alarm sounds to warn you! Also shown is the starter battery voltage. Apple users can download a slightly more sophisticated app, with extra features that can be purchased from the Apple app store. This app is compatible with iPhone, iPad and iPod touch and can also offer the Apple Watch App for iPhone. This requires iOS 9.0 or later.

  • Comes with 100 Amp 50mV shunt, and all necessary cabling to connect to the main service battery
  • Able to monitor a 12 volt lead-acid battery, or bank of batteries, with a total capacity between 5 and 600 Ampere-hours
  • The current consumption is approximately 2 mA
  • Monitors main battery voltage and current flowing into or out of the battery whilst calculating the best approximation of the state of charge and the time to charge or discharge
  • Audible alarm alerts if the charge becomes dangerously low when load shedding or if charging becomes necessary
  • A secondary input measures starter battery voltage
  • All information is transmitted via Low Energy Bluetooth (Bluetooth 4) and is viewable on any compatible device with a suitable app
  • The Android app is available to be freely downloaded from the Nasa Marine website, whilst a third party Apple app, with additional features, can be located on the Apple app store
