Lead-acid replacement UPS lithium battery
The CLF standard-voltage UPS battery is specifically designed to replace lead-acid batteries used in general-purpose UPS equipment. It is seamlessly compatible with UPS systems on the market that feature standard 12V SLA voltage ranges.
- Ultra-Compact & Lightweight: Only 1/3 the weight and 2/3 the volume of traditional lead-acid batteries, freeing up critical installation space.
- 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

Technical Insights & Support
Can this 12.8V 6Ah LiFePO4 UPS battery replace a traditional lead-acid battery?
Yes, this LiFePO4 UPS battery is designed as a reliable drop-in replacement for conventional sealed lead-acid (SLA) batteries in small-to-medium UPS systems. Compared to SLA batteries, it offers longer cycle life, better thermal stability, and is 1/3 the weight.
What is the typical backup runtime with this 12.8V battery?
Backup runtime heavily depends on your specific UPS load. As a reference: for a low load (10–20 W), expect around 20–30 minutes of runtime. For a moderate load (50–100 W), expect around 10–15 minutes.
How many of these 12.8V batteries can be connected together?
The built-in Smart BMS allows highly flexible configurations. You can connect up to 4 battery packs in series (creating a 48V system) and up to 10 packs in parallel to match common UPS DC bus requirements and vastly extend total capacity.
What protection features are included with the integrated BMS?
The battery integrates a robust BMS offering multi-layer security: overcharge protection, over-discharge protection, short-circuit protection, overcurrent protection, overtemperature protection, and internal cell balancing.
Where is this 0.5kVA battery module typically installed?
Thanks to its ultra-compact 150x68x94mm form factor, it is ideal for systems with limited installation space. Typical applications include small office IT infrastructure, building access control, supermarket backup registers, and security networking equipment.
Can I order custom voltage or capacity for my specific UPS application?
Yes, we support deep customization of LiFePO4 battery packs for specific UPS applications. Custom options include different nominal voltages, higher capacity ratings, various communication interfaces (RS485, RS232), and specific terminal connectors.
