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…

IMHO: this is where inline current shunts (Bluetooth or not) come in handy.
Fairly simple - measure AH In/Out of battery(s).
Also IMHO: anything that relies on battery voltage to calculate an implied SOC can't possibly take into account the parasitic loads our campers have in their calculation and therefore will always be an 'approximation meter' at best.
While the simple solution is to always have more AH then you need/use our truck campers have limited space to stuff more AH in. :)
