Description
The ECO-WORTHY Cubix 100 rack battery, manufacturer model ECO-LFP4810002, is a 48V-class LiFePO4 storage module with 51.2V nominal voltage and 5,120Wh energy. Its rack format and inverter communication interfaces make it a candidate for a designed stationary solar or backup energy system, rather than a portable power station with built-in AC sockets.
What this model offers
Bluetooth and WiFi monitoring are supported alongside CAN, RS485 and RS232 communication. Confirm the exact inverter protocol, cable and firmware compatibility; the presence of a port does not guarantee every inverter is supported. Ratings include 100Ah, a 100A BMS, 100A maximum charge/discharge and 50A recommended charging; the documented 100A discharge condition requires an initial temperature at or below 35°C. The EU manual gives 47kg, M8 terminals and up to 32 units in parallel, with series connection prohibited. Obtain a revision-specific installation drawing before specifying rack clearance because source dimensions conflict.

Choosing this battery for your system
Plan this battery as part of a stationary solar-storage or backup system with a compatible 48V-class inverter/charger. Match operating voltage, verified current limits and communication settings before buying. Allow suitable access, structural support, protection and ventilation; have installation dimensions confirmed for the delivered revision. AC output is provided by the separate inverter, not by the battery module itself. An expansion installation also needs matched modules, balanced wiring and the manufacturer commissioning procedure.
Capacity, power and realistic runtime
The manufacturer states 5120 Wh of nominal stored energy at 51.2 V. Amp-hours describe capacity; watt-hours are the more useful starting point when comparing loads at different voltages. An ideal runtime estimate is nominal Wh divided by the measured load in watts. Real runtime is lower because of conversion losses, standby consumption, temperature, discharge limits and the reserve you choose. This is a sizing method, not a tested runtime claim or a guarantee that every nominal Wh can reach your appliance.
Charging, protection and installation
Set the charger for LiFePO4 chemistry and the documented 58.4 V charge limit. Do not assume an existing lead-acid charger is compatible: verify its full charging profile and disable unsuitable equalisation or desulphation modes. Keep charging current within the model limit. Battery management protection is a last protective layer, not a substitute for an external fuse, correct wiring or normal low-voltage shutdown. Check polarity before connection and isolate the battery before working on the installation.
Charging and discharging have different temperature limits. Follow the exact ranges in the datasheet, allow for enclosure temperature and ventilation, and do not treat low-temperature charge protection as proof of a self-heating function. Outdoor exposure and water resistance must also be checked for the exact model; an IP rating from a different battery revision does not establish suitability for this one.
Manufacturer documents and included equipment
Use the PVShop datasheet together with the original manufacturer PDFs available on this page. The manufacturer brand and model are retained; the PVS code is the shop reference. The documents include supplied graphs or reference material where available and explain revision differences. Published figures are manufacturer statements, not PVShop laboratory results. The sale is for one battery, not a complete solar installation, inverter system, rack or charger bundle.
Delivery to the EU
Estimated total processing and delivery from European stock: 7–10 days. The supplier confirmed this estimate on 29 September 2026. Delivery is offered to EU countries; estimates are not a guarantee.
Frequently asked questions
Can I connect a solar panel directly?
Use a suitable solar charge controller between the panels and this battery. Match its battery profile, voltage and charge-current settings, and check the panel array against the controller input limits. A panel is not a regulated LiFePO4 charger. No solar controller or panel is included with this single-battery product.
Is it a direct replacement for every lead-acid battery?
No universal replacement claim is made. Check physical fit, terminal arrangement, charging profile and the equipment voltage limits. In a vehicle, alternator charging may require a compatible DC-DC charger. This is a storage battery; engine-starting or traction suitability is not established by its amp-hour capacity.
Can I build a larger battery bank?
Use only the connection arrangement explicitly allowed for this exact model in its manufacturer manual. Series connection changes system voltage; parallel connection changes capacity and demands balanced wiring and suitable protection. Use matched batteries and follow the commissioning procedure. Never assume that a connection limit published for another ECO-WORTHY model applies here.
