Battery Check100 Smartphone Telemetry

It is hard to get to locations that make it almost impossible to check a battery properly. A battery check on a smartphone gives the users critical battery information.

Do you want to know what happens with your vehicle’s secondary battery when travelling?

Whether using your 12V power or charging the battery, you want to be 100% sure your battery is in good health and has enough power.

To get instant information on your battery’s health and issues, use the wireless Bluetooth battery monitor BatteryCheck.

BatteryCheck is a simple device with an internal shunt. Connect it to your battery’s positive and negative terminals, download the BatteryCheck app, and pair your phone via Bluetooth.

Review 9 February

It’s been four days since I installed the BMPRO Battery Check 100 into the rear cargo area of my vehicle. Immediately it connected with my iPhone, even inside the house, and the car was in the garage.

I bought a 7-inch Tablet to mount as a permanent display in the rear of the vehicle, and it too works well, but the tablet’s Bluetooth must be different in some way, as it periodically disconnects. I don’t have an issue with this, as it is a small step to turn off/on the Bluetooth, and it’s fixed. What surprises me is the accuracy of the unit.

There seems to be little latency in the updates, and it displays exactly what is happening. Well done, BMPRO, I highly recommend it.

BatteryCheck is compatible with a range of standard 24 and 12V deep-cycle batteries. It provides real-time battery management data that allows users to monitor remaining battery energy via a simple-to-use app effectively.

Specially designed for recreational vehicles and marine deep cycle batteries, BatteryCheck allows monitoring up to 80A maximum charge or discharge. BatteryCheck is unsuitable for engine cranking applications and is not intended for under-vehicle bonnet use.

Monitored BatteryCheck Functions:

  • Voltage
  • Charge/Discharge Full Charge Current
  • Temperature
  • Estimated State of Charge (SoC)
  • Determined State of Health (SoH)
  • Discharge Time Remaining – Estimated

What our customers say

“As a battery power obsessive, I can’t recommend the BatteryCheck highly enough, knowing where my battery levels are and what I’m drawing and generating gives me the ability to manage my power usage in line with my solar generation. Running a freezer full time, lighting and charging an electric chainsaw is a balancing act made so much easier with a BatteryCheck.”- Callum.

Review 9 October 2019

I have just installed the new BatteryCheck100 in our Goldstream Mini pop-top. Previously, checking the status of the house battery was difficult, time-consuming and of minor detail. The information now provided via the BatteryCheck100+PRO app is excellent! Detailed levels of volts, amps, temperature and battery health are all updated in real-time and so convenient to access via mobile phone: a very well-made, relevant, Australian product and first-class application software.

Finally, download the app to your Android phone or Apple phone from the Google Play Store or Apple.
