Bluetti describes the set as dual B500K batteries that increase total storage for extended backup runtime; each battery is 5,120Wh (5.12 kWh).\u003c\/p\u003e\u003cp\u003eIf 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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery:\u003c\/strong\u003e B500K expansion battery, two supplied, for Apex 300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity per battery:\u003c\/strong\u003e 5,120Wh (5.12 kWh)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCycle life:\u003c\/strong\u003e over 4,000 cycles, rated by Bluetti for up to 10 years\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum system size:\u003c\/strong\u003e up to 100 kWh\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible stations:\u003c\/strong\u003e Apex 300, AC300, AC500, AC200L, AC200MAX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlso pairs with:\u003c\/strong\u003e SolarX 4K, Hub D1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e wall mount or trolley\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetti part number:\u003c\/strong\u003e B500K2-2-07-SPFUS-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis is genuine BLUETTI gear shipped direct from Bluetti's US warehouse.
