In this Video, we install the Battery Monitor on Apres providing voltage, current flow (draw or charge) and temperature monitoring for my 3 batteries - House 1, House 2 and Start. The device will run a program based on SensESP from the Signal K team and interface with my Openplotter system on my boat Raspberry Pi. We have changed direction on the shunt to a 250µohm Shunt from a 500µohm Shunt that we were previously using. The new shunt will package better with the batteries without modification.
The data that the device will provide is as follows:
For Each Battery
Voltage
Current Draw (+) or charge (-)
Battery Temperature
State of charge
