Common FAQs
The battery provides 4.8kWh of nominal energy and is intended for telecom base stations, remote sites, network backup and compatible UPS systems. Final quantity should be selected from the measured site load, required backup duration, usable depth of discharge, system losses, temperature and aging reserve.
Start with the site's average DC load and required backup hours. Divide the required energy by the usable system efficiency, then include depth of discharge, temperature, cable losses and capacity aging. A fixed backup time cannot be determined from the 100Ah rating alone.
Yes. The battery uses a 3U 19-inch rack format and measures 442 × 420 × 133mm, with a depth of 482mm when handles and terminals are included. Confirm cabinet depth, ventilation, cable clearance and support for the 43kg battery before installation.
Compatibility must be checked against the rectifier or UPS charging profile. This model specifies 53.3V equalization charge, 51.0V float charge and 40.5V discharge cutoff. Also verify charge-current limits, low-voltage disconnect settings, protection devices, cable sizing and communication requirements.
Parallel expansion requires an engineered system review. Confirm that the battery configuration, state of charge, firmware, communication settings, busbars, cable lengths, overcurrent protection and current-sharing design are compatible before connecting units. Ask LINEX to review the planned quantity and site architecture.
The battery provides RS485 and RS232 communication for integration with compatible site controllers, rectifiers or monitoring systems. Confirm the required protocol, connector, register map and alarm interface during project evaluation because communications must match the equipment used at the site.
It can be evaluated as a replacement where the rack, rectifier, charging range, low-voltage disconnect, cables and protection settings are compatible. Do not treat nominal 48V alone as confirmation. Existing lead-acid and lithium configurations should be reviewed before a staged or mixed-system upgrade.
Model documentation is available for UN38.3, CE, RoHS and FCC review, with a 5-year warranty. Confirm the exact documents required by the destination market and project tender before ordering, and provide the intended application, quantity and destination with the inquiry.
