Technical Insights & Support
Is this 76.8V LiFePO4 UPS battery compatible with my existing UPS system?
This battery is designed to match UPS systems with a nominal DC bus voltage around 76.8V and output up to ~4kVA. Compatibility largely depends on your UPS’s internal charging profile and BMS settings. We highly recommend checking your UPS technical specifications for seamless integration.
What backup runtime can I expect with this 9Ah battery?
Backup duration heavily depends on UPS efficiency and the actual load applied. As a reference: for a light load (~0.3kW), expect approx. 15–20 minutes; for a moderate load (~0.6kW), expect 8–12 minutes. Actual results will vary based on operating conditions.
Why choose a 76.8V high-voltage system over a traditional 48V setup?
For 4kVA loads, a higher voltage (76.8V) means the system draws significantly less current compared to a 48V system. This reduces heat generation, increases overall power transfer efficiency, and prolongs the lifespan of internal components.
How does it fit physically into our data center?
The battery is built with a standard 2U rack-mount profile. This allows it to act as a direct, space-saving drop-in replacement for bulky lead-acid battery packs in standard 19-inch 2U or 3U server racks.
What protection features are included in this UPS battery?
This battery includes multiple protection features through its integrated Battery Management System (BMS), including overcharge protection, over-discharge protection, short-circuit protection, overcurrent protection, and temperature monitoring. These safeguards help maintain safe, reliable operation.
Can this UPS battery be customized or configured for higher capacity?
Yes, we offer customization services for UPS battery solutions. You can easily connect multiple units in parallel for increased capacity, or inquire about alternative voltages and different communication interfaces tailored to your application requirements.
