Purchased two LifePo4 12v 100AH batteries. They are not connected to each other in any way, one is for graphs, one is for trolling motor.
It think the Victron smart shunt is the way to go.
It looks like there are two 500 Amp smart shunts, I can't tell the difference between the two other than the pictures look different.
I see: Victron Energy SmartShunt 500 amp Battery Monitor (Bluetooth)
and: Victron Energy SmartShunt IP65 500 amp Battery Monitor (Bluetooth)
I need to be able to
1. see charge on both batteries via bluetooth app
2. i would like to be able to have the round screen they sell at the front of the boat so all I have to do is look down to see the trolling motor battery life.
Which unit do I need?
