Which battery in the bank should Smart Battery Sense connect to?

Hi, I'm going to add the Smart Battery Sense to our Bluesolar 100/50 mppt controller to improve charging on our battery bank. The system is 24v and we have 4 x 6v FLAs in series. Which battery should the SBS be connected to (and presumably to both terminals on the same battery)?

with the info supplied

I would connect them to the same pos and neg connection that goes to all the loads.

otherwise we would need a diagram of how the current batteries are connected

It's a standard wiring configuration for batteries in series, as my diagram shows.

Did you read the manual?

obviously you'll need to connect to the most negative terminal and the most postive, otherwise you can't read the battery voltage.

@Boekel not clear what the ‘most negative’ or ‘most positive’ terminals are. Manual downloaded in 2021 didn’t have any reference.
