UL-certified LFP rack batteries are available through specialized energy storage suppliers and manufacturers adhering to international safety standards. Key vendors include Dongguan Xingyihang New Energy (CATL LFP100 cells), Beijing Pengguan Weiye Technology (FirstPower LFP series), and Guangzhou Dianjian Electronics (Vision Group V-LFP racks), all offering UL-listed configurations for industrial and telecom applications. Always verify UL file numbers (e.g., MH62111 for CATL systems) and rack compatibility before procurement.

What technical specs define UL-rated LFP rack batteries?
UL-certified LFP rack systems must meet UL 1973 for stationary storage and UL 9540A for fire safety. Typical specs include 48V nominal voltage, 100Ah–300Ah capacity per module, and IP55 enclosures. Pro Tip: Confirm thermal runaway containment via UL test reports—non-compliant units pose facility safety risks.
For example, CATL’s UL-listed 48V 100Ah rack battery delivers 4.8kWh per module with ±1% voltage tolerance. Transitioning from lead-acid? These systems provide 3x cycle life (6,000+ cycles at 80% DoD) but require BMS synchronization. Did you know improper parallel connections can void UL certification? Always use manufacturer-approved busbars.
Which suppliers offer UL-compliant LFP rack systems?
Major providers include CATL through authorized distributors like Xingyihang New Energy, offering modular 5–20kWh racks with UL 1973/9540A dual certification. Vision Group’s 48V V-LFP series features hot-swappable modules and CAN/RS485 communication, ideal for data centers.
Beijing Pengguan Weiye supplies FirstPower’s 12V 65Ah UL-listed batteries, though rack integration requires custom enclosures. Transitional challenge: While 12V units simplify replacement, 48V systems reduce cabling costs by 40%. Why risk compatibility issues when pre-configured racks exist?
| Vendor | Voltage | Capacity |
|---|---|---|
| Xingyihang | 48V | 100Ah |
| Vision Group | 48V | 200Ah |

FAQs
No—UL 1973 focuses on North American grid-tied storage, while IEC 62619 covers global industrial use. Projects requiring NEC compliance mandate UL 1973.
Can I expand UL-certified racks post-installation?
Only with identical modules and BMS firmware. Mixing batches risks imbalance—one hospital’s 20% capacity loss occurred after adding mismatched Vision Group modules.
