The RUiXU RX-LFP48120 is a 51.2V, 120Ah lithium iron phosphate battery that stores 6.14kWh in a 19-inch, 3U rack module. It is the higher-capacity sibling of the RUiXU RX-LFP48100, with 6.14kWh per module instead of 5.12kWh, so a rack or cabinet holds more energy with the same number of batteries.
It is built for homeowners, installers and small businesses who pair a 48V battery bank with a hybrid or off-grid inverter for backup power, solar storage or off-grid living. Every unit has a 180W self-heater, Bluetooth app setup and RS485 and CAN inverter communication.
Each battery stands 5.24 inches (3U) tall and fits a standard 19-inch rack, with mounting ears that bring the front panel to 19.00 inches wide. At 6.14kWh per module, six batteries make 36.84kWh and ten make 61.40kWh, the capacities RUiXU lists for its 6-slot and 10-slot battery cabinets.
Lithium batteries should not charge when the cells are too cold. RUiXU's data sheet lists the 180W heater starting at or below 41°F (5°C) and stopping at or above 53.6°F (12°C), which helps in an unheated garage or utility room. The battery is still rated for indoor use only.
The RUiXU Battery app connects over Bluetooth to show the status of each battery and the whole bank, set the inverter communication protocol and install over-the-air BMS firmware updates. When you connect several batteries together, they assign their own addresses automatically.
The master battery talks to the inverter over CAN or RS485, so the inverter can follow the battery's charge and discharge limits and state of charge. RUiXU lists CAN support for Victron, SMA, Studer Innotec, Sofar, Sol-Ark, Solis, GoodWe, Deye, Growatt, SAJ, LuxPower, Megarevo, INVT, Sermatec, TBB, MUST, Sunsynk and Schneider, and RS485 support for MPP, Voltronic and RCT.
The built-in BMS guards against overcharge, over-discharge, overcurrent, short circuits and high or low temperature, and it balances the cells. A pre-charge circuit limits inrush current when the battery connects to an inverter or charger, and the front panel has a breaker, power switch and SOC lights.
A dry-contact input on the front panel accepts an emergency stop switch for rapid shutdown. When the switch is pressed, the BMS trips the breakers on the master and every connected battery.
RUiXU rates the RX-LFP48120 for 6,000 or more cycles at 90% depth of discharge and lists a 15-year design life. The battery carries a 10-year warranty from RUiXU.
Home Backup. Paired with a compatible hybrid inverter, a bank of RX-LFP48120 batteries keeps lights, a refrigerator, internet and other critical loads running during a grid outage.
Solar Self-Consumption. Store daytime solar production for the evening, or charge when utility rates are low and use stored energy when rates are high.
Off-Grid Homes and Cabins. With an off-grid inverter and solar array, the battery bank becomes the main energy store for a home, cabin or workshop that has no utility service.
Small Business Backup. RUiXU designed the battery for small shops, offices and light industrial sites too, where it can cover critical loads during outages and trim demand peaks.
Both are 51.2V lithium iron phosphate server rack batteries in a 3U format. The RX-LFP48120 holds 6.14kWh per module, about 20% more than the RX-LFP48100's 5.12kWh, and self-heating is standard on every unit. It is 20.08 inches deep, so check your rack depth first.
A lead-acid bank needs watering or venting, loses capacity when it is discharged deeply and wears out after far fewer cycles. A LiFePO4 rack battery needs no watering, communicates with the inverter and keeps a steady voltage through most of its charge.
Rack modules let you start with the capacity you need today and add batteries later. A single large wall-mounted unit can be simpler to install, while rack batteries split the weight into 105.82 lb modules.
Add up the kilowatt-hours your loads use over the outage or overnight period you want to cover, then divide by 6.14kWh to estimate the number of batteries. Also check your inverter's battery current. RUiXU's manual allows one daisy-chain power connection up to 120A and two from 120A to 240A; above 240A, use a busbar or battery cabinet.
The RX-LFP48120 mounts in a 19-inch rack, RUiXU's bracket rack, or RUiXU's 6-slot and 10-slot battery cabinets, with two screws on each side. It is rated IP20 for indoor use. A qualified installer should handle the wiring and commissioning, RUiXU recommends a DC breaker between the battery bank and the inverter, and any connection to your home's electrical panel should be done by a licensed electrician under local codes and permits.
RUiXU lists CAN or RS485 support for more than 20 inverter brands, including Victron, SMA, Sol-Ark, Deye, Growatt and Schneider. Confirm your exact model, set its protocol in the RUiXU Battery app and use the matching communication cable.
The batteries connect in parallel and assign their own addresses. RUiXU's 6-slot cabinet holds up to 36.84kWh and its 10-slot cabinet holds up to 61.40kWh of RX-LFP48120 batteries, and larger banks are possible.
RUiXU backs the RX-LFP48120 with a 10-year warranty.
Each battery includes a communication cable and a grounding cable for linking to the next battery, plus short red and black 4 AWG cables for a busbar. The power cables to the inverter or busbar, the main grounding cable and the inverter communication cable are sold separately and should be sized for your system.
The RUiXU RX-LFP48120 Server Rack Battery gives you 6.14kWh of LiFePO4 storage in a 3U module, with self-heating, Bluetooth setup and closed-loop inverter communication on every unit. If you need help sizing a battery bank, choosing cables and busbars or matching the battery to your inverter, the Outbound Power team is ready to help.

I must say, I have never experienced such awesome customer service with this company. Jam my sales rep was awesome and answered all my questions. She also was able to ship my power station and it was delivered early by two days. Again, the service was the best to any other company I have dealt with. Thank you Bill for your commit to customer service with your employees. Ralph
I’m so happy I found this site! Outbound Power has so many great products and I was really excited to see the price. I’ve been waiting for Amazon prime days to buy something, a very expensive item, but I happen to see it on this site and I snatched it right up and saved over $500!!! a delivery was quick and actually a day earlier than what they thought it would be.
I can honestly say Outboundpower Company exceeds their mission statement. The word that defines this organization is "Outstanding". The the Quality of products they sell is Outstanding. Their recent price matching is Outstanding by exceeding my expectations and truly customer focused. They really make a difference; a refreshing find these days. Their customers are definitely the most important part and purpose of their work.
In closing, I seldom offer reviews even when asked. However, I was motivated to expend the time and effort to recommend OutBoundPower without reservation; because they truly earned my respect. R. Kaiser
I have purchased over $20,000 of solar equipment from Outbound Power over several purchases. They have the best pricing and the best hands-on customer service. I always shop other sites but always end up back at Outbound Power. They are awesome!
I wanted to leave a new review, as support reached out to me and clarified some things I was unclear about. This thing is amazing! It seamlessly switches over to backup power without me noticing, and makes being inconvenienced by power outages a thing of the past. I originally purchased it for just backup power, but I'm finding that I can really offset energy costs by attaching solar panels pretty easily, and building up my solar grid at my own pace.
Support confirmed that the unit can handle 50A when connected to the grid, accommodating a maximum of two F3800s at the same 50A when the power is out. That drops to 25A if you only have one F3800.
Support also took my feedback to enhance the app capabilities, and provide more visibility into the individual component's utilizations. I've been very impressed by their level of support, and am excited to see the improvements they continue to make.
I originally purchased this thinking I would just connect a manual transfer switch via the 30A plug and use it as a backup generator. However, once I discovered the Home Power Panel, and its ability to seamlessly switch over to backup power automatically, I was sold! It was easy to use and easy to install. I can confirm that it supports 6000W at 25A. It is a beast!! I am excited to buy a second one in the future, and it has already been amazing maintaining power when the grid goes down.
I am excited to see some improvements in the app though. It is a bit basic. I would like to see things like detailed monitoring of the different circuits, historical monitoring data, and the ability to configure alerts (like a circuit is consuming more power than you expect it to). Otherwise, it is pretty great!
Outbound Power's seamless ordering and rapid shipping has kept me a customer for many years. I have bought 5 different ECOFLOW products and always have been pleased with Outbounds customer service. Thanks Bill
The portable fridge came in about 5 days and was even cheaper than the manufacturers sale price. An employee even called me to make sure that I was satisfied with the product which doesn’t ever happen. As soon as I got it I unboxed it and immediately put it into use. It took about 25 minutes for the unit to get to 30 degrees when I had it set to its lowest setting. I went shopping and 30 minutes later it was at -4f. Even once I filled it up with some frozen and some slightly cool food items it got up to about 15f and dropped back down to -4f within about 60 minutes. Beats the heck out of ice for sure.
As for the company they went above and beyond to earn my future business. I thought something was missing from the box, so I sent an email and they responded within minutes, fortunately it was my mistake and I overlooked a part of the packaging and found the item. So I sent another email saying it was my fault and I had found the item. I really appreciate the service you all provide.
You can’t go wrong with Outbound Power and Anker. Just got my Extension Battery, as well I just order a 400w Anker Solar Panel, now I wil have total of 1000w to charge these two units
Hight Recommend Outbound and Anker Products top Quality.
Thank you Bill for the Great Service.
Just wanted to let you know that the Anker Solix F3800 plus, with an expansion battery, and the generator cable arrived promptly and in excellent condition. I want to mention that your company does the right thing, even though the customer may not know it. When I ordered the equipment, I did not know that there was a promotion for a free solar panel based on the amount of the order. I was happily surprised when the free solar panel was delivered.
Rest assured that I will recommend your company as it has the best prices around, and because it does the right thing for it's customers.
Thank you!
This website, its owner/employees, and products, came highly recommended . After careful researching, I purchased the Ankers 2600 and their 400W solar panels.
From the moment I pressed the enter key and completed the transaction, the clock was ticking. THIRTY, count ‘em! Thirty hours later, Fed Ex was delivering my purchase. Everything was of the highest quality packaging.
Definition of Customer Service?
When you EXCEED A CUSTOMERS EXPECTATION!
Bill, Emanuel, Ankers & Fed Ex exceeded WAY BEYOND my expectations!!!!!
What are YOU waiting for?!
I have now ordered over $6000 of solar components from Outbound Power and the customer support and interaction is second to none. Highly communicative, helpful, and speedy delivery’s have all added to several great experiences. Not to mention their prices beat everyone in the solar market. I’m still setting up my equipment but once it’s completed, I’ll provide a review on the Ecoflow products a well!
Good pricing. Good reputation. Fast service dealing with a real person if needed. Service availability after the sale.
The price was right and the delivery was fast. I can hardly wait till this item is on sale again, need a couple more. Thanks
The river 3 plus is a great power station. I’m very happy so far. It does what I want it to do. I like the app. It’s quiet. It’s very nice looking too.
