Two B500K expansion batteries in the Apex 300 configuration. Bluetti describes the set as dual B500K batteries that increase total storage for extended backup runtime; each battery is 5,120Wh (5.12 kWh).
If you already own an Apex 300 this is the straightforward way to go from a weekend of off-grid camping to a week. Bluetti rates the B500K at over 4,000 cycles and up to 10 years, and the Apex 300 system can grow to 100 kWh. Mount the batteries on a wall in a garage or basement bay, or keep them on a trolley so they move with the station. Bluetti's page also answers how many B500K units an Apex 300 accepts and whether B500K, B300K, B300 and B300S can be mixed; check that answer before combining battery types.
