Charging/monitoring start batteries

Our house bank on our boat is charged by solar and a quattro and everything is monitored through a Cerbo GX.

We also have start batteries for each of our main engines and one for the generator. These batteries have no monitoring and are charged with a factory AC powered charger.

We would like to upgrade the chargers for these batteries and have one that charges both main engine start batteries and one the charges the generator start battery. Additionally, we would like the voltages of these batteries to be visible in the Cerbo.

Our house bank is 24v and the start batteries are all 12v.

It doesn’t matter if the charging is by ac/dc or dc/dc chargers.

In any case, we only need under 10 amps for each.

What are some options for doing this?

Check the orion tr charger line, there are 24/12 models there.

And they have a ve.direct port for connection to thr cerbo, s o you can monitor the 12v battery.
