Jackery Battery Pack 1000 Plus Expansion Battery 1264.64Wh is a 1264.64Wh LiFePO4 expansion battery dedicated to the Explorer 1000 Plus system. Key verified details are 1264.64Wh capacity, LiFePO4 chemistry, 4000 cycles to 70% capacity, dedicated compatibility with Explorer 1000 Plus, and up to three packs supported for 5056Wh total system capacity. This makes it suited to extending explorer 1000 plus runtime, building a modular 1000 plus system, and users who already own the compatible base station, with the product's role and operating limits clearly defined by Jackery's published specification. This pack adds energy storage to the Explorer 1000 Plus but does not operate as a standalone portable power station; outputs and system control remain centred on the base unit. For ownership, confirm the exact compatible Explorer before ordering and treat the pack as additional storage within that system. Its value is extra runtime and modular capacity; it does not turn into a separate general-purpose power station when disconnected from the supported base unit.
