Technical Insights & Support
Which UPS systems is this 25.6V 6Ah battery compatible with?
This battery module is specifically engineered for high-rate UPS equipment up to 1kVA. Its slim 1U profile makes it ideal for built-in UPS series commonly found in modern data centers and IT server racks.
Why is the 7.5C high-rate discharge critical for 1kVA UPS backup?
UPS systems require massive current bursts during power transitions. Supporting up to 7.5C (45A) discharge, this LiFePO4 module ensures critical equipment remains powered without voltage drops during the most sensitive switching moments.
What are the advantages of LiFePO4 over traditional Lead-Acid batteries?
LiFePO4 batteries offer 4-5 times the service life of lead-acid, 1/3 the weight, and 2/3 the volume. With a calendar life of 10+ years and zero maintenance, the Total Cost of Ownership (TCO) is significantly lower.
Can it replace a standard 24V lead-acid battery string?
Yes, absolutely. Because its nominal voltage is 25.6V, it serves as a perfect direct drop-in replacement for systems that currently use two standard 12V SLA (Sealed Lead-Acid) batteries wired in series.
What protection features does the Smart BMS include?
The integrated Smart BMS provides autonomous protection against overcharge, over-discharge, over-current, and short circuits. It also includes abnormal temperature protection at 65±5°C to ensure maximum operational safety.
Does the battery support remote monitoring and integration?
Yes. Equipped with standard RS485 and RS232 communication interfaces, the battery can communicate real-time status and diagnostic information with UPS controllers or external monitoring systems.
