Short Summary

The Flexopower Extra Battery 2560Wh is designed to expand the storage capacity of the Lithium3000 Portable Power Station for longer backup power and extended off-grid use. It is a practical upgrade for clients who need more runtime for camping, caravans, trailers, load shedding, or mobile power applications.

Why This Product

Many clients start with a portable power station that covers the basics, then realise they need more runtime for longer trips, heavier daily use, or more reliable backup during load shedding. This 2560Wh expansion battery helps solve that problem by increasing the capacity of the Flexopower Lithium3000, giving clients a more flexible and scalable power system without replacing the main unit.

Key Features

2560Wh expansion capacity – adds substantial extra battery storage to extend runtime on the Flexopower Lithium3000.
Built for Lithium3000 only – designed specifically for compatibility with the Flexopower Lithium3000 Portable Power Station.
Scalable system – add up to 6 extra battery modules to reach a maximum system capacity of 17.5kWh.
LiFePO4 battery chemistry – uses Lithium Iron Phosphate for long service life and dependable performance.
Approx. 10-year service life – supports long-term value for clients investing in backup or off-grid power.
High output capability – rated up to 3500W max and 70A for system support.
Durable battery construction – built with a square aluminium case for strength and reliability.
Multiple safety protections – includes protection against short circuit, over-current, over-voltage, low-voltage, overload, and over-temperature.
Compact expansion format – adds capacity while remaining manageable for installation and storage in suitable setups.

Ideal For

Clients who already own a Flexopower Lithium3000 Portable Power Station
Camping and overlanding clients who need longer off-grid power duration
Caravan and trailer owners wanting more battery capacity without changing their full system
Clients needing extended load shedding backup at home or in the office
Buyers looking for a modular power upgrade rather than a completely new unit
Clients who value scalable backup power for South African conditions
