EXTB 31448
High-Capacity LiFePO4 Telecom Battery (314Ah, 5U)
High-Capacity Lithium Battery Backup for Telecom and Energy Storage Sites
The EXTB 31448 brings 314Ah of LiFePO4 capacity and 15.1kWh of usable energy to telecom and energy storage sites that need high-capacity backup in a standard rack footprint. Fifteen cells in series using an artificial graphite anode deliver consistent 48V output with low self-discharge and no memory effect. Exicom's in-house BMS manages over and under-voltage, over-temperature, and cell equalization, while RS485 and dry contact ports enable remote monitoring across PC, SMPS, PCS, and RTU systems. Current-limiting charging, inbuilt equalization, and sleep functions keep the battery healthy over the long run. 5U, 19-inch rack-mountable with detachable mounting ears.
