The Jackery HomePower 2000 Plus v2 Battery Pack is the modular building block designed to scale your home backup ecosystem. Engineered with premium LiFePO₄ chemistry, this expansion pack seamlessly plugs into your base HomePower 2000 Plus v2 to multiply its runtime. By stacking multiple packs via the heavy-duty DC expansion ports, you can scale your system from a nimble 2048Wh base unit up to a massive 12kWh home energy fortress capable of sustaining critical appliances through extended power outages.
Plug-and-Play Expansion | 6000+ Life Cycles | Dedicated Solar Controller
Double Your Runtime Instantly The v2 Expansion Battery Pack acts as an instant energy reservoir for your home generator. When paired with the main generator, the internal logic automatically creates a synchronized power pool—requiring no extra app setups or software configurations. True to the v2 standard, it features an upgraded, compact design that matches the footprint of your main unit for easy, secure stacking.
- Instant Capacity Multiplying: Adds an extra 2048Wh of modular energy to your setup. Daisy-chain up to 5 packs per single v2 base station to reach a maximum of 12kWh.
- Independent Solar Charging: Unlike standard passive battery sleeves, this pack features a built-in independent charge controller, allowing you to feed solar panels (up to 1400W Max) directly into the expansion unit even while the main unit handles home loads.
- Built to Last 16 Years: Utilizes the same ultra-durable LiFePO₄ (LFP) core architecture as the v2 generation, retaining 70%+ health even after 6,000 full charge-discharge loops.
- 12-Layer Intelligent BMS: Continuous monitoring protects the expansion line against short circuits, overvoltages, thermal spikes, and overcharging.
- Tool-Free Stacking: Includes a high-gauge, heavy-duty orange expansion bridge cable that locks tightly in place to prevent accidental disconnects.

FAQs
How to Securely Daisy Chain: Always turn OFF both the main HomePower v2 unit and the Expansion Battery Pack before clipping the thick expansion bridge cable into place. Ensure the matching sides (labeled A/B) align perfectly with the terminal markings on the back of the hardware.
- Can I use this battery pack by itself? No. This expansion module does not have standalone AC outlets or USB ports. It acts purely as an external power cell that feeds its capacity directly into a compatible base generator.
- How do I know the main unit detects the battery? Once connected and powered on, a dedicated external battery icon will illuminate on the LCD display of your main HomePower unit, and the total combined capacity percentage will populate in your Jackery smartphone app.
- Can I charge the battery pack separately from the generator? Yes! Because it features its own integrated DC input terminal, you can connect solar panels or a 12V car charger directly to the battery pack to juice it up independently while your main unit is deployed elsewhere.
- Does it charge at the same rate as the main unit? When plugged directly into the wall via the main unit, the entire stacked system fills up uniformly, taking roughly 2 hours to charge both units simultaneously under ideal grid input conditions.
