BMV 700 on 24 V System

I am running two 12V, 100 amp hour Lithium Phosphate batteries on a 24V trolling motor will a BMV700 monitor stay of charge for this system?

Yes. I have one monitoring my 24v bank.

It is similar to connecting to a 12v system. Shunt on the most negative and little red wire on the most positive of the bank.so it reads all 24v.

Thank you for the response. I don’t understand which are the most negative and most positive terminals? How do you determine most negative and most positive?

Connect to the ends of the battery where you get the 24V, or where you take off your loads.

Some installers make the mistake of connecting the positive to any positive in the bank.

If you have two 12V batteries in series, to make a 24V battery, you then use the terminals at the ends of the battery string.
