Solera battery question

[plstaylo]

Re. the battery under the driver's feet for a 2013 Solera. I have unearthed it and wondered what I am looking at. Is it a dual function battery, and is it completely sealed- am I right? How good are these batteries? Or battery.

On a related theme, we bought our Solera secondhand, and I note that there is no accessory battery in the engine compartment, but a nice big empty space for one- is this SOP for a new Solera? Has anyone added an accessory battery, and if so, what kind? I am a bit nervous having just one battery supplying all the electrics- if indeed there is only one on-board battery serving two functions (deep cycle and engine starting) as I suspect, and would like to know what to put in as backup.

And yes, I am a newbie. One who is very grateful for this forum. I just haven't been able to find anything that answers these issues, and the manual is useless for this.

Check under the steps into the coach. There is likely 1 or 2 deep cycle batteries there for the coach. I assume you are worried about only using the MBS engine battery for everything?

Interesting question re putting another battery in the engine compartment. Some MBS cargo vans have this becasue they have more stuff running off the batteries- buses, delivery vans etc. I plan to do lots of boondocking and it would be nice to have a reserve. I can not find a boost feature on mine for pulling from the coach batteries.

The battery under drivers feet is the chassis battery and is not powering coach systems.

The one under the floor board in the cab is an AGM sealed battery. Main function is for starting the engine. The two group 27's under the step are for the coach power. The battery manager under the black plate to the left of the stair well, manages the charging in flight and on shore power.
