Oscal BP3600 Extra Battery

The Oscal BP3600 Extra Battery is a high-capacity expansion module designed specifically for the Oscal PowerMax 3600 and PowerMax 6000 rugged portable power stations. Featuring a massive 3,600Wh capacity and durable LiFePO4 chemistry, this battery allows you to scale your system from a portable camping unit to a massive home backup solution capable of sustaining your household for days during a blackout.

Why Choose the Oscal BP3600 Extra Battery

The BP3600 transforms your PowerMax from a weekend camper into a serious survival tool. While a single PowerMax station is powerful, 3.6kWh might drain quickly when running central air conditioning or heaters. Adding just one BP3600 doubles your runtime instantly. Moreover, its unique scalability allows you to daisy-chain up to 15 batteries, creating a colossal 57.6 kWh energy storage system—enough to power an average home for over a week off-grid.

Benefits of the BP3600

• Decade-Long Lifespan: Built with automotive-grade LiFePO4 (LFP) cells, this battery is rated for over 3,500 charge cycles before hitting 80% capacity. This means you can use it daily for nearly 10 years.

• Rugged & Reliable: Like the PowerMax station, the BP3600 is built tough. It features fire-retardant (UL94V-0) casing, drop-proof durability (up to 0.8m), and an IP21 rating against vertical water drops.

• Stackable Design: The units are designed to stack vertically, saving floor space in your garage, RV, or tiny home while keeping your power setup organized.

• Smart Management: Connects via the Oscal Smart App (WiFi/Bluetooth) to monitor real-time battery levels, temperature, and health status alongside your main unit.

Frequently Asked Questions

Q1: Can I use the Oscal BP3600 as a standalone power station?

No. The BP3600 does not have its own AC outlets or USB ports. It is an expansion battery that must be connected to an Oscal PowerMax 3600 or PowerMax 6000 to function.

Q2: How many BP3600 batteries can I connect?

You can connect up to 15 BP3600 units to a single PowerMax station. This expands the total system capacity to a massive 57,600 Wh (57.6 kWh).

Q3: How do I charge the extra battery?

The BP3600 charges through the main PowerMax station. When you plug the station into a wall outlet, solar panels, or EV charger, it will charge the main unit and then pass power through to charge the connected BP3600 batteries automatically.

Q4: Is it compatible with other brands?

No. The BP3600 uses a proprietary connection and communication protocol designed exclusively for the Oscal PowerMax series. It will not work with EcoFlow, Bluetti, or Jackery units.

Q5: How heavy is it?

It weighs approximately 83.1 lbs (37.7 kg). It features built-in handles for lifting, but due to the weight, it is recommended to use two people or a dolly for moving it long distances.
