EXTB 10048
48V LiFePO4 Telecom Battery for Space-Saving Backup (100Ah, 3U)
Space-Saving Lithium Battery Backup for Compact Telecom Sites
The EXTB 10048 packs 100Ah of LiFePO4 capacity and 4.8kWh of usable energy into a compact 3U chassis, giving space-constrained telecom sites a lighter, smaller backup option without giving up performance. Its integrated smart BMS manages current-limiting, over and under-voltage, and over-temperature protection, while dual RS485 and RS232 ports deliver remote visibility through SOC, alarm, and run status indicators. Rated for over 3000 cycles at 80% DOD and 90%+ charge-discharge efficiency, it operates across a wide temperature range from -20°C to 60°C. Capacity extends through parallel connection as your site grows.
