Hi Everyone,
Earlier this year I put in SmartSolar MPPT 100/30 supporting a 220W solar panel, and a BMV-712. this powers two 100 AH AGM house batteries plus 1 AGM 76AH starter battery. the house and starter banks are connected via a blue sea SI-ACR automatic charging relay.
My 12 year old shore power ProNautic 12-20p charger just died and I'm looking at the blue smart IP22 30AMP 3 Bank charger to replace it. In order to get temperature sensing, I understand I can either add a $42 BMV-712 temperature sensor or purchase a stand alone smart battery sense for an extra $10. (prices in Canadian, eh)
So the $10 difference is negligible. Question is:
I know if I use the BMV-712 I give up the option of monitoring my starter battery voltage or the mid point house battery voltage with the BMV-712 - should I care about using these options and which temperature sensing approach would be recommended?
Thanks Everyone!
