I am looking to add a smart shunt to 2 12v 100ah Lithium Iron Phosphate batteries in series in order to monitor state of charge.
I have an onboard battery charger with positive and negative leads to each battery.
Would both negatives attach to the shunt?
Also would the bilge area on my boat (where my batteries are) be a suitable environment for the shunt?
Thanks
I don't think there is a solution if you individually charge your series batteries.
Or maybe I understood wrong and the batteries are not in series?
If the batteries are in paralel, you connect the negative wires from each battery to the "Battery Minus" side of the Smart Shunt and everything else (all other negative wires from loads and chargers) to the "Load" side of the SmartShunt.
Regarding the environment question: you can put the shunt inside a IP65 enclosure and use cable glands for all wires.
