It is built with automotive-grade cells and an integrated BMS for frequent cycling, and it works across five BLUETTI platforms — Apex 300, AC200L, AC200MAX, AC300 and AC500 — subject to the correct connection cable. Worth knowing before you buy: this is an expansion battery, not a power station. On its own it can only supply power through its built-in 12W USB-A port; household AC output requires a compatible station.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCapacity: 2,764.8Wh nominal LiFePO₄\u003c\/li\u003e\n\u003cli\u003eCycle life: 6,000+ cycles to 80% of original capacity\u003c\/li\u003e\n\u003cli\u003eWeight: 65.04 lb\u003c\/li\u003e\n\u003cli\u003eCompatible with: Apex 300, AC200L, AC200MAX, AC300, AC500 (cable varies by model)\u003c\/li\u003e\n\u003cli\u003eExpansion: up to six per Apex 300 via CA90 connection\u003c\/li\u003e\n\u003cli\u003eStandalone output: 12W USB-A port only\u003c\/li\u003e\n\u003cli\u003eFast charging: 80% in as little as 45 minutes in a supported AC300\/AC500 configuration\u003c\/li\u003e\n\u003cli\u003eWarranty: 3+1 years with registration\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eBLUETTI part number: B300K2-UN-GY-BL-SPFUS-00\u003c\/p\u003e\u003cp\u003eGenuine BLUETTI, shipped direct from BLUETTI’s US warehouse.
