BMV 712 reading the house bank plus two starter batteries

Hello.

Have a couple of question please:

1. On my Cat I have a house bank batteries and two starters batteries . All different locations. House bank in near galley, and starters batteries (1 next to engine Port 1 next engine STB). My question is:

Would it be possible to obtain reading of those separate systems? I understand is possible with house bank plus one starter battery, but I want make sure that would an extra input connector in the shunt for the second starter battery.

2. I understand the supplied shunt has 500amps capacity, right? My house bank currently hold 7 batteries, that combine can generate 700 amps. I guess that should be problem, correct?


Thank you,

Erick

@Erick De Moraes One of the inputs to the shunt on the BMV will have to come from your house battery bank. The other can be used to monitor a secondary starter battery's voltage. That being said you could use a switch like this: https://www.bluesea.com/products/8300/Contura_Switch_DPDT_Black_-_ON-ON to switch between the two starter batteries to view their voltages.

Eric, did you solve the problem of monitoring the two start batteries? I have the same setup and would like to check both starter batteries.
