Title: Arkpax Ark Pro Extra Battery 2300Wh

⚠️ This expansion battery does not function as a standalone unit. It requires the Arkpax Ark Pro portable power station to operate.

The Arkpax Ark Pro Extra Battery adds 2300Wh of IP67-rated LiFePO4 capacity to your Ark Pro system. Unlike expansion batteries from most brands, this one carries the same IP67 waterproof and dustproof rating as the main unit — meaning your expanded system is just as rugged as the base station.

Each Extra Battery expands your total from 2300Wh to 4600Wh. Stack up to ten packs to reach 25.3kWh. Connects via built-in cable and recharges through the Ark Pro main unit at up to 2300W.

Best for: Extending Ark Pro runtime on multi-day job sites • Marine and offshore applications • Emergency response requiring 2+ days of power • Off-grid cabins with high daily consumption

WHY RPC? We are an authorized Arkpax dealer. Free U.S. shipping. Price match guaranteed. Backed by Arkpax’s 2-year warranty.
