Timely topic for me. I run a 100Ah & a 50Ah (lfp4), circa 2018, in parallel. They both had individual BT which I loved. Early this year they, the 100 first followed by the 50, both lost BT transmission. The batteries seem fine otherwise, as the charging parameters, which I follow with a SmartVictron 100/30, have remained consistent. I prefer not to mount or run a monitor. I liked BT on my phone. This Smartshunt seems like my answer.
Since I have to run a negative (parallel) cable from the 100 to the 50, it will share attachment with the shunt cable. I think it’s best to attach the shunt to the 100ah battery. It’s ok to have the parallel cable & the shunt cable mounted together, correct? As long as I attach nothing else to the “battery minus”?
Will the shunt display only the 100ah SOC? It probably would display two 100ah in parallel (200ah) as a battery bank? But will it display SOC for a 150ah bank since the batteries are not equal ah? Thoughts?
I have a simple battery box setup, connection to solar panels, connection to camper power. I do not have an inverter. I’d like to confirm my recipe for shunt hookup. Thanks ahead for any input.
