I have x2 12v 100AH batteries hooked in series for a 24v trolling motor.
I talked to Victron support and they told me that I would need two smartshunts for my system using the NOCO GEN5x3 12v 3 bank charger. Or I would need to buy a dual voltage 24v / 12v charger, cheapest I can find is the Iconic for $369.00. It is way cheaper to buy another $115 shunt. Also it is a lot easier job to just install another shunt vs changing my charging setup.
I am unsure on how to wire this up correctly and how to set it up in the app.
Below is a diagram of what I am thinking but would one of the batteries read 24v and the other 12v? I would like to configure it to where the smartshunts only monitor each battery and not the system as a whole.
To complicate this even more I also have a minn kota alternator that charges the battery while running, which is another reason I don't want to switch to a 24v charger because the shunts would be thrown off by the charge coming from it. It is a 2 bank DC-DC charger, 12v @ 10 amp each wired to the same spots as the NOCO minus the starter battery. This isn't on the diagram because it cluttered things up pretty bad.
Also what would a single shunt monitor, if I remove the shunt to the right and leave a single shunt in the middle? Would that monitor the battery to the left? If so could I then just do a DC meter function on the AUX/midpoint wire for the battery to the right?
Thank you in advanced for help :)
