RUiXU Lithi2-16 51.2V 314Ah LiFePO4 Battery Energy Storage
The RUiXU Lithi2-16 packs 16.07kWh of LiFePO4 capacity into a wheeled, wall-mountable battery rated for ≥9,500 cycles at 80% depth of discharge. Built-in Fuma wheels make it easy to move into place, and an anti-tip wall anchor keeps it secure once installed — indoors or out, thanks to its IP55-rated, electro-coated steel enclosure.
A built-in BMS communicates over RS485/CAN with most major inverter brands, including Victron, SMA, Sol-Ark, Solis, Deye, Growatt, Goodwe, and Sunsynk. The Lithi2-16 is expandable up to 32 units in parallel for roughly 512kWh of total storage, making it equally suited to a single home backup system or a larger commercial installation. Renewable Outdoors is an authorized RUiXU dealer, and every Lithi2-16 we sell is backed by RUiXU's 10-year limited warranty.

Why the Lithi2-16 Stands Out
Expandable to ~512kWh
Connect up to 32 units in parallel to scale from a single residential battery to a full commercial energy storage system.
Gas Aerosol Fireroof Protection
An internal fire-suppression module improves fire protection for both the electrical wiring and the battery cells.
IP55 Outdoor-Ready Enclosure
An electro-coated steel case resists rust and corrosion, using the same coating process common in automotive body shells.
Tool-Less Quick Plugs
250A continuous overcurrent capacity with long-term anti-loosening and heating protection, for an easy, secure connection.
Built-In Wheels + Wall Anchor
Four concealed heavy-duty Fuma wheels make it easy to move into place, with an anti-tipping wall mount for secure installation.
Self-Heating & Smart Balancing
Keeps the battery charged in cold temperatures, with intelligent double-equilibrium cell balancing for reliable long-term performance.

Customer Reviews
Overall rating: 4.8 / 5 from 30 reviews.
I got the first pair of RUiXU Lithi2-16 batteries in February from Renewable Outdoors. I was very happy with the service and speed that they were shipped. Any time I have had a question I have gotten an answer within 1-2 business days.
I had 2 open posts on the RUiXU busbars so I decided to get another pair to bring me to 64 kWh of storage. These batteries came with the PP140 cables in the box so they were even cheaper than the February set of batteries. Again the order was sent to RUiXU within a couple of days. A credit was made to my charge card for the extra set of cables I ordered. That were not needed as they were now included with the batteries. It was then just a matter of waiting for the trucking company to deliver them. That was about 2 weeks.
I have to be honest, I was nervous at first. But I needed replacement batteries an all my research pointed to the Ruixu as the best value. So I pulled the trigger. A few days later I got the shipping confirmation and a few days after that the batteries were delivered. Not a bit of hassle the whole way. These were a replacement for the FLA batteries that came with my DC Solar trailers, and I’m happy to report that the BMS in the Ruixu batteries communicate perfectly with my SMA Sunny Island 6048-US inverters, something that many battery companies failed to accomplish (from internet reports). So I feel very fortunate to have found Ruixu! I wouldn’t hesitate to recommend them.
These are excellent batteries. I’ve purchased 3 from this company (I have 5 total now) and the prices are great and they ship fast.
Price per kWh is excellent and super simple to install. Firmware updates are a little tedious but not terrible. U.L. Listed and can go indoors (built in fire protection) or out. Will connect to pretty much any inverter out there.
The battery work perfect, I have just 1 issue with the inverter communication, but ruixu fix it with the firmware update, I can run my hose for 2 or 3 days whitout problem, love it
Worked very well with the Ezg4 12000xp ..I just texted the battery and I've been running it for 3 days...running my entire home..las about 14-16 hrs... I thing works better than EG4 powerwall by far..
Hello,
The battery is nice however there seems to be an issue with the battery measuring it's own internal temperature. The first battery I bought from you showed 32 degrees no matter what condition and now with both batteries hooked up no temperature is displayed on Solar Assistant.
So a little bit of a problem when there should be none for the price I payed for premium UL listed battery. Maybe it is easy fix, do you have any ideas? Thanks.
Lack of communication and tracking was not reliable delivery service was not great but renewable outdoors was amazing we used them 3 different times and will do again great amazing customer service all the way 5 stars for them.
I have tried several times to send messages about the battery that I got it will not charge and I can’t figure out what the problem is if I could speak to someone, it could probably be cleared up very quickly 1-505-615-1443 Jim
Battery arrived in great condition, well packaged. It is a two person job to flip the unit upright when moving it off the pallet. Unit was easy to insall using standard supplied ethernet cable connecting to a EG4 6000xp. I love the wheels that come attached to the base of the unit. Just be very carefull how you push or pull on the unit to move it around because it is very top heavy. Follow the supplied instructions on how to roll the unit.
Other than being heavyweight! There not a bad thing I can say bout this ruixu 16kwh battery simply perfect for my application being off grid! The quality is great and built to last no doubt, and BMS has its own access for replacement if it ever needs it! Thanks Nate
