For now I plan to use a volt meter I have installed in my camper for SoC level which should be good enough for my use. I've "calibrated" the camper meter with a multimeter at the batteries when the isolation switch is switched off to eliminate parasitic draw. So far there no significant difference between the camper volt meter and the multimeter but I haven't taken measurements when the batteries are in a low SoC.
Good luck with that. As an example on my NL that switch only breaks the connection to the Converter/charger - the jacks+controller and fridge are directly connected to my battery(s) bypassing that switch.

When it comes to accurate SOC’s, I kinda see the Bluetooth feature mostly as marketing gimmickry, while their real utility is for checking individual cell status…Further, it remains to be seen how the Bluetooth will respond to two batteries in parallel or series connection…My view is there’s no substitute for the credibility of a Victron shunt based meter..
Of all possible features, the Bluetooth feature wouldn’t be high on my ‘must have’ list - JMO

Upon edit, the aforementioned Bluetooth SOC inaccuracy may be associated with personal charging practices, and the number of less than a FULL charge, charge cycles which overtime leads to cumulative meter drift, whereas the Victron could be FAR better at resolving cumulative drift…Just MO…

A little late to the thread but just throwing this out there. Instead of 2 100ah batteries is there a chance you would have the space for one 200ah battery? For example -
JITA 12V 200Ah Plus LiFePO4 Battery
Wiring is much easier and solves the problem of trying to balance the cells across 2 different batteries.
