What bmv for 2 batteries.

Currently i have a bmv-700 monitoring my auxilary battery. Which is working fine. However I would like to monitor my starter battery also as i have a cerbo gx and also nuc poweren on full time on the starter battery. My auxilary battery is being charged via mppt via solar panels and the cyrix distributes this to my starter battery when the auxilary battery is full.


However i have no view if the usage of the starter battery. Should i buy another bmv700 or a bmv which supports 2 batteries (712?) .

If you want to monitor the SOC of your starter battery you need another BMV.

A BMV 702/712 or the SmartShunt can only measure the voltage of a second battery.
