Key Technology: The Heated "Blade" Cell
The standout feature of the Hanchu 9.4kWh unit is its Blade LFP (Lithium Iron Phosphate) technology. Originally developed for the high-safety requirements of the automotive industry, these cells are thinner, lighter, and far more resilient than traditional battery blocks. Crucially, the 9.4kWh model includes Integrated Auxiliary Heating as standard. This allows the battery to maintain a full 100A charge and discharge rate even in freezing temperatures (as low as -10°C), where other batteries would significantly throttle their performance.

Smart Monitoring with the iESS App
The Hanchu iESS mobile app provides a comprehensive real-time overview of your home’s energy ecosystem, with data updates every 10 seconds. The platform is fully compatible with Octopus Energy smart tariffs (including Flux, Agile, and Go). Through the app, you can automate your battery to charge during cheap off-peak windows and discharge during high-value peak periods, maximizing your "export profit." It also features Weather Compensation, automatically adjusting its strategy based on local forecast data to ensure you always have enough stored power.
Scalability and Design
Hanchu systems are designed to grow with your needs. The modular units can be stacked (up to 16 batteries in parallel) to meet even the highest energy demands. With an IP65 rating, they can be safely installed outdoors or in garages, and their compact footprint makes them roughly 40% smaller and lighter than many comparable lithium-ion alternatives.
