Common FAQs
The battery provides 7.2kWh of nominal energy for telecom base stations, remote sites, network backup and compatible UPS systems. Select the number of modules from measured site load, required backup duration, usable depth of discharge, system losses, temperature and the reserve required for capacity aging.
Multiply the site's average DC load by the required backup hours, then account for usable system efficiency, depth of discharge, temperature, cable losses and aging reserve. Actual runtime depends on the complete load profile and cannot be determined from the 150Ah rating alone.
This rack-mounted module measures 482 × 440 × 178mm and weighs 60kg. Confirm rack width, depth, vertical clearance, load capacity, ventilation, cable routing and service access before installation. The cabinet and shelf structure must support the battery safely throughout operation and maintenance.
Check the charging profile against 53.3V equalization, 51.0V float and 40.5V discharge cutoff. Also confirm charge-current limits, low-voltage disconnect settings, cable size, protection devices and communication requirements. Nominal 48V alone does not confirm compatibility.
Parallel expansion requires an engineering review of the battery configuration, state of charge, firmware, communication settings, busbars, cable lengths, current sharing and overcurrent protection. Provide the planned quantity, rectifier details and site load so the proposed architecture can be checked before installation.
RS485 and RS232 communication are available for integration with compatible site controllers, rectifiers or monitoring systems. Confirm the protocol, connector, register map and alarm requirements during project evaluation because the communication interface must match the equipment already used at the site.
Replacement is possible only after checking rack space, rectifier voltage, charging current, low-voltage disconnect, cables, fuses or breakers and monitoring requirements. Existing lead-acid and lithium configurations should not be mixed or staged without validating the power-system logic and protection coordination.
Documentation for UN38.3, CE, RoHS and FCC review is available, with a 5-year warranty. Confirm the exact documents required by the destination market and project tender before ordering, and include the intended application, quantity, installation environment and destination in the inquiry.
