38.4V 5Ah LiFePO4 UPS Battery
(2kVA Backup Module)
This 38.4V 5Ah LiFePO4 battery pack is listed for high-rate UPS applications around ≤ 2kVA. Before selection, confirm the UPS DC bus, charging profile, required discharge current, communication protocol, connector and rack clearances against the final system configuration.
The CLF Standard Voltage Series UPS Battery Pack is engineered specifically for short backup power applications. Built with LiFePO4 cells, the pack is intended for short-duration backup use during power interruptions; actual runtime depends on UPS efficiency, connected load, battery condition and cutoff settings.
- High-rate discharge: The listed 12C rating corresponds to 60A for a 5Ah pack; confirm permitted current and operating limits for the quoted configuration.
- BMS protection: The listed protection functions include overcharge, over-discharge, over-temperature and short-circuit protection; confirm thresholds and communication behavior for the final configuration.
- Standby charging: Confirm float/charge voltage, current and temperature limits against both the battery specification and UPS charger profile.
Designed for UPS backup applications, this 38.4V battery is listed around a 2kVA system rating. Confirm DC bus, output demand, charger settings, rack dimensions and interfaces before integration; backup continuity depends on system design and load.
- Data centers and enterprise IT server rooms.
- Banking facilities and financial trading systems.
- Medical equipment and precision laboratory instruments.
- Commercial office environments and security/surveillance systems.
The listed SPCC enclosure measures 470 × 207 × 35 mm and is presented in a compact 1U format. Check rack depth, support and retention, terminal access and cable clearance before specifying it as a replacement.

UPS battery selection & project planning
38.4V 5Ah LiFePO4 UPS battery for 2kVA-class systems
This 38.4V, 5Ah pack is listed at 192Wh for UPS systems up to 2kVA. The page specifies 12S2P, 60A maximum continuous discharge, RS232, an Anderson SB50 terminal and a 470 × 207 × 35 mm SPCC enclosure—details that make it a distinct short-backup selection, not a generic 48V replacement.
UPS compatibility and replacement checks
How to interpret this configuration
The listed 12C / 60A continuous rating relates to the battery-side demand; the 2kVA UPS class does not prove the system draws within that limit. Check DC bus, charging set-points, cutoff and surge demand against the selected UPS documentation.
Typical system context: This SKU is most relevant to a 38.4V UPS battery bus with a short backup objective, such as a small server/network room, security-monitoring installation or industrial control panel. It should not be selected for a 48V or other bus solely because the UPS kVA appears similar.
Interface and installation details to confirm
- Cell configuration: 12S2P; published enclosure: 470 × 207 × 35 mm, SPCC, IP21; listed weight: 5.1 kg.
- Communication is listed as RS232 only for this configuration; RS485 is not listed.
- Output terminal: Anderson SB50. The table lists 30V over-discharge protection and 32V recovery.
LiFePO4 retrofit checklist
- Check the exact 38.4V battery bus and charger/cutoff window.
- Compare continuous and surge current requirements with the listed 60A maximum continuous value.
- Verify SB50 polarity, RS232 protocol/pinout, mounting and 470 × 207 × 35 mm clearance.
- Confirm whether any project needs a communication interface beyond RS232; it is not listed on this configuration.
Runtime planning and OEM/ODM project intake
Plan from the actual UPS load
The published runtime reference is 5–15 minutes. Treat it as a planning range only; actual runtime depends on load profile, UPS efficiency, usable energy, cutoff, state of charge, temperature, age and system behavior. A review needs the UPS model, measured load, DC-bus/cutoff data and required ride-through time.
What to include in a quotation request
Send the UPS model, 38.4V bus and charging window, load/current profile, required runtime, SB50 cable and RS232 protocol needs, rack clearance and quantity.
A B2B configuration discussion can cover the BMS communication requirement, connector and harness routing, mounting details, housing/label and target quantity. Send the UPS model and interface specification; the published page lists RS232, so do not assume RS485 or CAN.
