I'm putting together my RV solar setup and would like to use a battery temperature sensor, as I understand my Victron MPPT 100/50 charge controller can optimize it's charging of the batteries if it knows their temperature. I currently am using 2 x 6v flooded golf cart batteries, but plan to upgrade to LiFePO4 batteries in the future, so would also like the protection of low temp cutoff. I also have the Victron 500 Amp Smart Shunt. It appears that I can get a temp sensor for the shunt and then the shunt will communicate to the MPPT via bluetooth. I guess I would rather connect the temp sensor directly to the MPPT and not rely on that bluetooth connection if thats possible and recommended.
Which temp sensor should I get and is it connected through the VE.Direct jack on the MPPT or some other way? Are there other good reasons to just connect the temp sensor through the shunt and allow it to talk to the MPPT over bluetooth that I'm not aware of?
Thanks!
