Jackery Battery Pack 3600 Plus – 3.6kWh Expansion Battery for Home Backup Power
Expand your energy storage and extend your backup runtime with the Jackery Battery Pack 3600 Plus, a 3,584Wh LiFePO4 expansion battery designed to add substantial capacity to compatible Jackery home backup power systems. Built for the Jackery HomePower 3600 Plus and HomePower 3600 Pro Max, this additional battery pack gives you more stored energy without replacing your existing power station.
Whether you're preparing for extended power outages, hurricane season, emergency situations, or simply want more capacity for everyday energy storage, the Battery Pack 3600 Plus provides a practical way to expand your home battery backup system.
Add 3.6kWh of Extra Battery Capacity
With 3,584Wh of energy storage, the Battery Pack 3600 Plus adds approximately 3.6kWh of additional battery capacity to a compatible Jackery system.
When connected to a HomePower 3600 Plus, up to five additional Battery Pack 3600 units can expand the system to approximately 21.4kWh of total energy storage. Jackery also states that two compatible HomePower 3600 Plus or HomePower 3600 Pro Max systems can be configured with up to 10 battery packs for a combined capacity of up to 43kWh.
This expandable architecture makes it possible to increase your home energy storage capacity as your power requirements grow.
Designed for Longer Home Backup
More battery capacity means more stored electricity available when the grid goes down. Adding the Battery Pack 3600 Plus can help extend the runtime of compatible Jackery power stations during blackouts, hurricanes, severe weather, and extended power outages.
It is especially useful for homeowners who want to keep essential equipment operating for longer periods, including refrigerators, freezers, Wi-Fi equipment, lighting, televisions, fans, and other compatible appliances.
Instead of purchasing another complete portable power station, the expansion battery lets you build on the Jackery system you already own.
LiFePO4 Battery Built for Thousands of Cycles
The Battery Pack 3600 Plus uses LiFePO4 battery chemistry and is rated for more than 6,000 charge cycles while retaining at least 70% capacity under Jackery's stated conditions.
That long cycle life makes it suitable for customers looking for a long-lasting home backup battery that can be used repeatedly rather than reserved only for emergencies. Jackery states that the battery is designed to provide more than 10 years of reliable home backup under its specified conditions.
Compact 3.6kWh Expansion Storage
Despite its substantial capacity, Jackery describes the Battery Pack 3600 Plus as 34% smaller and 29.3% lighter than others in its class, using its patented CTB technology.
The battery weighs approximately 55.1 pounds and measures approximately 14.8 × 12.5 × 9.0 inches. Dual handles make the unit easier to move when installing or repositioning your home backup system.
Designed for Extreme Temperatures
The Battery Pack 3600 Plus is designed to operate in temperatures ranging from approximately -4°F to 113°F (-20°C to 45°C) for both charging and discharging.
Jackery also highlights high-temperature-resistant ceramic membrane battery cells and safety technology designed to help protect against thermal runaway. This makes the battery suitable for a wide range of environmental conditions when used according to the manufacturer's specifications.
Simple Expansion for Your Jackery Power System
The Battery Pack 3600 Plus connects to a compatible Jackery power station through the included expansion cable, allowing you to increase available energy storage without purchasing an entirely new power system.
It is specifically designed for compatibility with the Jackery HomePower 3600 Plus and HomePower 3600 Pro Max.
