Oscal BP3600 3600Wh Additional battery for PowerMax 3600

Expansion battery module for increased system capacity

OSCAL BP3600 is an additional expansion Battery, intended for use with the main PowerMax 3600 system. It's a modular battery with the same capacity as the base unit (3600Wh), allowing for easy increase of total energy storage without replacing the main device.

This makes the system much more powerful and suitable for long-term power supply, as the capacity can be gradually upgraded according to the user's needs.

3600Wh additional capacity for longer Autonomy

Each BP3600 unit adds 3600Wh of energy, significantly extending the operating time of the entire system. This is especially useful for long-term power outages, camping, RVing or off-grid use where maximum independence from the electrical grid is important.

With multiple units, the system turns into a very powerful power source that can power devices for longer and more stably.

Modular design and easy system expansion

The main advantage of the BP3600 is its modularity – units can be added incrementally, meaning the user starts with a basic system and upgrades it later. This allows for flexibility based on usage and budget.

The connection to the main PowerMax 3600 system is designed to act as a “plug-and-play” extension, without complicated setup.

Lithium-iron-phosphate technology (LiFePO4)

The battery uses LiFePO4 cells, which are known for their long lifespan, higher number of charging cycles and better safety compared to classic lithium batteries. This means stable operation even during long-term and intensive use.

Such technology is suitable for reliable energy systems where durability over many years is important.

Use in real-world scenarios

The BP3600 is primarily intended for users who need greater energy independence. It is used when camping, in motorhomes, in the field, in workshops or as a home backup during power outages.

With additional batteries, the system can be adapted for both basic use and more demanding energy needs.

Who is the module suitable for?

It is suitable for users who already have or are planning to use a PowerMax 3600 system and want to increase its capacity. Ideal for those who want a long-term scalable solution without replacing the entire system.

Nerd's opinion

Nerd's opinion: this is typical "LEGO for energy” approach – base unit + additional modules. It is not cheap, but the concept is very practical because the system can grow with the needs. The biggest value is flexibility and scalability, not just one big battery.
