Description
CEC approved 16kWh LiFePO4 battery
RUIXU Lithi2-16 51.2V 314Ah Battery
A high-capacity 16kWh lithium iron phosphate battery for serious home storage, off-grid systems, backup power and larger 48V inverter builds. The RUIXU Lithi2-16 is the battery we recommend when customers want strong value without stepping down to small-cell budget hardware.
51.2V / 314Ah
IP65 outdoor rated
>=9,500 cycles
Why we rate this battery
The most important part of a battery is not the logo on the outside. It is the cells, the BMS, the enclosure, the safety design and how well the battery works with the inverter system.
The RUIXU Lithi2-16 uses large-format 314Ah LiFePO4 cells. In our experience, this cell format is one of the best directions for long-life stationary storage because it allows a large battery module with fewer cells and fewer internal cell connections than many smaller-cell designs.
We like it for high-usage homes, backup systems, off-grid builds and customers who are thinking in terms of a 10 to 20 year battery system rather than the cheapest possible upfront purchase.
Large-format cells
314Ah cells are the core reason we like this battery. The same cell class is now appearing in newer premium home battery systems.
Outdoor-ready
IP65 rating, corrosion-resistant finish and a built-in heater make it better suited to real Australian installation conditions.
Flexible 48V platform
Works with many common 48V inverter platforms when correctly cabled, configured and commissioned.

Rebate and installation notes
This battery may suit rebate-eligible systems when paired with approved equipment and installed under the correct program rules. Eligibility depends on the full system design, installer, property, location and current rebate requirements.
- Confirm battery and inverter compatibility before ordering.
- Confirm whether your system is on-grid, off-grid, backup-only or part of a larger hybrid system.
- Use a qualified battery installer familiar with AS/NZS 5139 and the inverter brand being used.
- For a full installed package, consider our Deye + RUIXU bundle options.
Frequently asked questions
Is this battery suitable for Victron systems?
Yes, it can be used with compatible Victron systems when correctly configured, but cabling and protocol setup matter. A Type B communication cable may be required.
Can I install one battery now and add more later?
In many designs, yes. The system can scale, but the inverter, cabling, protection, battery settings and physical layout should be planned from the start.
Is this only for off-grid?
No. It can suit off-grid, hybrid and backup systems when used with compatible equipment. Grid-connected systems must still meet network, inverter and rebate requirements.
Why choose a 16kWh battery module?
A 16kWh module gives a useful amount of storage without needing many smaller batteries. It can simplify larger systems and makes 32kWh, 48kWh and bigger battery banks easier to plan.
Need help matching this battery to an inverter?
Tell us what inverter you have, what you want the system to do, and whether you are planning grid-connected, backup or off-grid use. We can help check whether the RUIXU is the right fit.
