Hi 9w6vx I like my electronic gadgets and alarms and found my bike batteries were getting poor to charge plus the HRV issue. I had not normally used my battery conditioners on the bikes but due to Covid shutdown and lack of use of cars and bikes for several months in the UK issues were showing up and I had thought about a simple voltmeter in the car whilst driving as I had checked the HRV voltage while parked and saw the strange low voltages and started to look at the circuit and the negative voltage control system.
On Youtube I saw the BM2 battery monitor and I thought just the job, no more getting the hood up (Bonnet in the UK) to check the battery condition, same as my wife's Jazz not driven for months. I can check the voltage and status of the battery. I now leave the bikes on the conditioners and can see how they switch and manage the charge keeping them ready for a ride. Vstrom 1000 and Honda Crosstourer DCT.
The App is free it has Bluetooth to each module; left connected; you select the one to check it displays the status % and if on charge, will gather the last connection data of the battery and display/download the battery volts, starts and stop, plus charging and I have seen over 1 months worth of information.
Screen shot of the battery status yesterday as I walked by the car.
The HVR screenshot show the battery condition then car start, starts to recharge battery then ECU shuts the voltage down below what the battery had as a standing charge taking power from the battery !!!! Turn on headlights (its daylight) voltage goes back up to charge battery, arrive and engine stopped, the end blip shows when I turn off headlights and battery has little drain.
Trip Friday 17th
Battery charging ok while it was dark, then daylight it starts discharging until headlights put on. Arrival 08:40 and battery settles down to normal. The return trip I thought I would see what state the battery would be as it was 100% at the start of my 2-3 hr trip back. I was shocked to find the battery condition had dropped from 100% to 68% and the voltage peaks/spikes can be seen.
This data can be exported to excel
Crank Test showing voltage drop
Charging test to prove the alternators was working.
Note I have no interest in this company and find it only as a good tool.... to see if the battery is failing.
