Overview
The YueQi 51.2V mobile energy storage battery family is a 16-cell LiFePO4 range for home backup, solar storage and portable energy projects. The catalog covers six models, from about 5 kWh to 15 kWh, with CAN, RS232 and RS485 communication on the main series. The 51.2V nominal bus connects directly to 48 V class inverters and charge controllers.
The 16S1P layout gives a charge end voltage of 58.4 V and a discharge cut-off of 44 V on the main series. Two later models in the catalog list a 40 V cut-off, which is noted in the table below for confirmation.
Typical Applications
- Home backup power and load shifting with a 48 V class inverter
- Solar storage paired with MPPT charge controllers
- Mobile energy storage for site power, events and remote equipment
- Battery cabinets for OEM energy storage products
Key Features
- 16S1P LiFePO4 configuration at 51.2 V nominal
- LCD touch screen on the main series (to be confirmed for each model)
- CAN, RS232 and RS485 communication interfaces
- Protection functions listed in the catalog: over-charge, over-discharge, over-current, short circuit, over-voltage, reverse-charge, equalization and temperature (to be confirmed against the BMS datasheet)
- Housing designed for humidity, dust and impact resistance per the catalog

Charge temperature: 0 to 45 C on the main series; 0 to 55 C on the A and B models (to be confirmed). Discharge temperature: -20 to 60 C for all models listed. The catalog lists the second model in the A/B column as YQ48300-A on the B page; the correct model code is to be confirmed.
Certification
The product literature shows the CE mark and the UN 38.3 transport test mark for the mobile energy storage range. Certificate copies available on request. Certification must be confirmed per model before it is cited in a tender or import filing.
OEM and ODM Options
YueQi supports OEM and ODM projects for 51.2V battery modules and cabinets. Options to discuss include capacity, enclosure, display, communication protocol, terminal layout, label and packaging. Minimum order quantity, lead time and tooling costs are to be confirmed in writing for each project. Please send your target energy, peak current, inverter brand or communication requirement, and destination market.
Next Steps
Request the full datasheet for the model you are evaluating, the BMS protection list, the communication protocol description and the certificate copies. Items marked "to be confirmed" will be verified and confirmed in writing before they appear in a quotation.
Request catalog specifications, sample terms and certificate copies for this series on the quote page, or compare the other product lines.
