I might definitely lean more in the direction of SiO2 where (in the following order):
1) If weather conditions might include ‘extended excursions’ at or below 32F while having no provisions for keeping battery above 32F (e.g. heated compartment or batt. blanket - note, Li safely discharges to about -4’ish F). For some this criteria could be paramount..
2) Initial cost...However, this issue is often mitigated by the long cycle life of LiFePo4, while LiFePo4 entry-fees seem to be slowly dropping...
3) Ultra high amperage discharge rating of SiO2’s well exceeds all other competing Battery types - depends on one’s amperage requirements?
4) Where Recharge ‘C rate’ is not a critical parameter - this more in terms of off-grid (32F +) solar peak-period harvesting windows.
5) Where ‘required-usable’ DOD (depth of discharge) and voltage-sag (vs LiFePo4 alternative) can be offset by having more a/hr capacity - assumes no space or weight restrictions....Much depends on other variables surrounding one’s own particular camping style - not always of primary consideration or limitation.
6) Where unattended self-discharge rate can be mitigated by an active charging device - something to consider when off grid...
FWIW, My camping style is mostly off-grid desert (40th’ish parallel north) with solar harvesting - for ultra low battery internal resistance, limited truck camper space and other camping style reasons I opted to go the Li route, but that’s just me (“actual user experience may vary” - lol!)..
