Printed as "Max 200A" (with "Recommended 140A") for charge current in the RUiXU Lithi2-16 specification sheet, captured on September 25, 2026; the sheet sets the charge and discharge current values side by side after their labels.

Not printed for this model in the documents on file. Revised on 1 October 2026: RUiXU prints a maximum charge current of 200A and DC power figures (rated 7KW, maximum continuous 10KW), but no charge power.
Printed as "Max charging voltage 58.4V" in the RUiXU Lithi2-16 specification sheet, captured on September 25, 2026; the sheet prints the charge voltage separately as 56.8V.

Battery weight
137 kg302 lb converted
Manual and spec sheets give different weights.
The Lithi2-16 operation manual V1.8 prints Weight ~137kg (302.0lb); both current spec sheets print 145kgs. Neither says whether packaging or accessories are included.
Printed "Weight ~137kg (302.0lb)", an approximate figure, in the Lithi2-16 operation manual V1.8; both spec sheets print 145kgs; captured on September 26, 2026. Revised on 26 September 2026: Owner rule of September 26, 2026: the exact-model manual's value is primary. The spec sheet's 145 kg is kept beside it and the flag stays; the two earlier alternatives repeated these same two claims and are replaced by them.
145 kg / 319.67 lb
Manufacturer specification; operating and installation conditions apply.
Calculated: Manual v1.8 allows 32 units; calculated using datasheet 16 kWh rounded capacity. Manual rounds each unit to 16.1 kWh. Required busbars and inverter limits apply.

Printed as "Expandable From 16kWh to 257kWh" in Lithi2-16 specifications, Specification sheet, product description. Revised on 1 October 2026: The specification sheet prints "Expandable From 16kWh to 257kWh"; the manual prints a 32-unit parallel limit but no system energy.
Datasheet heater-stop Celsius text conflicts within the document
Page 1 prints 53.6°F (12 °C); page 2 prints 53.6°F (5°C). The page 2 Celsius figure contradicts page 1’s conversion of the same Fahrenheit figure. Both passages remain as printed; no corrected maker value or operating procedure is selected.
The retained datasheet page 1 prints: "self-heating starts ≤41°F (5°C), ≥53.6°F(12 °C) self-heating stops". Page 2 separately prints: "Self-Heating starts ≤41°F (5°C) ≥53.6°F(5°C) self-heating stops". Each passage is retained as printed; neither is corrected or chosen as an operating procedure. This does not establish a cell charging-temperature threshold. Scope is the retained two-page datasheet, not an assumed later revision.
RUiXU's manual V2.1 prints, for the Link IN port, pin 3 "Emergency Power OFF" and pin 6 "Emergency Power Off +", with the remark "Pins 3 and 6 are the emergency stop button connection points." Added from member correction report suggestion-7a27f880 (2026-10-18). RUiXU prints no list of compatible inverters or stop switches here.
Charge table and installation working range differ
Version V1.8 prints -25~55°C in its charge row and separately -10°C–50°C in section 4.1 as the maximum working range. Both retain their own scope and location; no procedure or cold-cell charging threshold is inferred. The datasheet also disagrees internally on the Celsius heater-stop text.
Manual Version V1.8 prints Charge: -25~55°C; the retained datasheet page 1 prints charge: -25~55°C (-13~131°F). This is the charge row as printed, not a cell-temperature threshold or a selected operating procedure. Separately, the same manual section 4.1 Installation environment, PDF page 38 (printed page 33), gives Working temperature: -10°C–50°C (maximum operating range), 15°C–30°C (optimal temperature); that installation range is recorded separately and is not merged with this charge row. The datasheet heater passages and their disagreement are retained with the self-heating fact. These citations establish only the Version V1.8 manual and the retained datasheet; applicability to later document revisions is not established.

Installation working range differs from the charge table
The section 4.1 maximum working range is -10°C–50°C; section 3.1.2 charge range is -25~55°C. Both are separately located and retained with their printed scope, without merging them.
Printed separately as Working temperature: -10°C–50°C (maximum operating range), 15°C–30°C (optimal temperature). This is the installation-environment working range, not a replacement charge or discharge limit. The same manual’s section 3.1.2 table, PDF page 27 (printed page 22), separately prints Charge: -25~55°C. Version V1.8 scope only; applicability to later document revisions is not established. No operating procedure is chosen.

The problem I had with the RX04 firmware. Was when winter came and it was cold enough for the batteries to require heating to charge. They went into emergency stop unless the power was coming from the grid. The reason was that the solar in the morning if a cloud came by the PV input would drop below the current needed for the heaters on the 4 batteries. That would cause them to shut down.
RUiXU tech sent me TS24 that allows them to heat for 2 hours from stored energy in the battery's. It also solved a charging issue that TS23 firmware had of charging at max amps until hitting the cell/pack overvoltage protect limits. I also bought 2 more in Sept 2025 to max out the open ports on the RUiXU buss bars. so now I have 64kWh of batteries. I would buy them again. I got all of mine from Renewable Outdoors.com The shipping was from RUiXU in California. It took bout time about a week for them to ship. I'm assuming it was due to holding them to fill a truck heading my direction.
I purchased two of these and self installed them. My local AHJ has been...quite difficult to work with demanding documentation on top of documentation over and over. Ruixu support has been *stellar* in tracking down and providing every piece of documentation. Installation was very straight forward, but these are HEAVY batteries. So aside from the physical difficulty, which is no negative but something you do need to be prepared for, installation was a breeze. Getting them setup as a pair was pretty straightforward. I will say, getting the EPO (emergency power off) functionality working is kinda wonky (requires some secret touch screen shenanigans), but once enabled works great.
I combined these and paired them with a dual SolArk 15k setup and had zero issues getting them to talk together. They're happily humming along for the last month or two with no issues. I was even able to lookup their modbus info and get custom monitoring setup on them with basically no hassle and an ESP32 pushing data into HomeAssistant
Ordered and got a pallet shipment, like, 2 days later. Exceptionally fast shipping (but, I suppose I'm lucky to be in the same state). Regardless, very fast delivery and came super well packaged. Very happy. Had to special order some cables later on and had zero issues getting those quickly either. Great experience.
I have used the Ruixu Lithi 16 for about a month and have had no issues. Plugged it into my Ruixu Sunon 12 and it worked and communicated easily. Hardest part was getting it onto the wall mount as it took 4 of us to do. Was also impressed with the shipping box Ruixu used to ship it, was wood and very sturdy.
The Evidence score uses the priorities you choose. It counts published documents, such as certificates and warranty terms, and it compares a documented figure with the best documented figure of the same kind. It does not count owner reviews, and it is not a verdict on product quality or on how many people have reviewed it. A low score can mean little is documented, or that a documented figure is below the best of its kind. Undisclosed data scores 0.
Missing for this product: Warranty energy disclosure evidence needed; Cell model disclosure evidence needed.

The warranty term and the lifetime energy are each scored against the best documented value for a home storage battery: a value earns its share of that best, times the weight. A documented value always earns points; an undisclosed one earns 0.
