12.8V 6Ah LiFePO4 UPS Battery
(0.5kVA Lead-Acid Alternative)
Specifically designed as a reliable lithium alternative to traditional sealed lead-acid (SLA) batteries in general UPS equipment up to 0.5kVA. Featuring an ultra-compact footprint and massive flexible expansion capabilities up to 4S10P.
Lead-acid replacement UPS lithium battery
The CLF standard-voltage UPS battery is a lithium alternative for eligible 0.5kVA UPS systems. Confirm the charging profile, voltage window, current demand, connector, dimensions and BMS/interface before ordering.
- Installation Fit: Compare pack dimensions and weight with the available battery compartment, and confirm connector and charging requirements.
- High-Rate Output: Supports sudden high-power demands with up to 7.5C continuous discharge.
- Unmatched Scalability: Highly flexible system design allows up to 4 battery packs in series and 10 in parallel to meet any custom capacity requirement.
- Integrated Protection: Smart BMS provides full defense against overcharge, over-discharge, over-temperature, over-current, and short circuits.
With a compact and lightweight design, the battery is suitable for UPS systems with limited installation space and indoor operating environments.
Typical application scenarios include:
- Data centers and enterprise server rooms
- Supermarket and retail backup power
- Building systems and access control
- Networking equipment and small industrial controls

UPS battery selection & project planning
12.8V 6Ah LiFePO4 UPS battery for compact 0.5kVA systems
This listing identifies a 12.8V, 6Ah (76.8Wh) pack for compatible UPS applications up to 0.5kVA. The listed 45A maximum continuous discharge and 8–15 minute backup-time reference help frame selection, but the UPS model and actual DC load determine suitability.
UPS compatibility and replacement checks
How to interpret this configuration
Treat the 0.5kVA label as a UPS class, not as a compatibility guarantee. Confirm the battery-side DC bus and charger profile first, then compare the UPS demand with the listed 45A maximum continuous current and the BMS cutoff/recovery values of 9.2V and 10.8V.
Typical system context: The listed 150 × 68 × 94 mm format and 0.5kVA class make this page most relevant to compact UPS replacements such as small-office IT, access-control panels, point-of-sale equipment and security/network devices—only where the DC bus, current and charging profile match.
Interface and installation details to confirm
- Published envelope: 150 × 68 × 94 mm; terminal: F2 Faston, with terminal customization listed.
- The product page lists RS232 and RS485; confirm the protocol, pinout and data points required by the UPS.
- The page lists 4S10P under series-parallel connection, but does not define whether it describes cells or external battery-pack wiring. Confirm pack-level topology before connecting modules.
LiFePO4 retrofit checklist
- UPS model and nominal battery-bus voltage / permitted charge window
- Continuous and peak battery-side current plus required runtime
- F2 terminal polarity, cable arrangement and BMS communication needs
- Available mounting envelope and the meaning of the listed 4S10P topology
Runtime planning and OEM/ODM project intake
Plan from the actual UPS load
The page lists 8–15 minutes as a reference, not as a result for every 0.5kVA load. Runtime changes with actual load, UPS conversion efficiency, usable battery energy, cutoff, state of charge, temperature, age and system configuration. For a project estimate, send the UPS model, measured load, DC bus, cutoff voltage and required hold-up time.
What to include in a quotation request
Send the UPS make/model, battery DC bus, charge window, load, runtime target, required quantity, F2 polarity/cable details and enclosure dimensions. This gives the project review the information needed to check the pack against the system.
For an OEM/ODM inquiry, specify whether the project needs this nominal-voltage class or a different pack, then provide the UPS interface, cable/terminal, enclosure, label and monitoring requirements. Configuration and integration details should be agreed against the target UPS before a build is quoted.
