Siemens 6EP4143-8JB00-0XY0 SITOP BAT8600 LiFePO4 48V/358Wh Battery DC UPS Module

The Siemens 6EP4143-8JB00-0XY0 is a SITOP BAT8600 LiFePO4 battery module that stores 358 W-h at 48 V DC for the SITOP UPS8600 uninterruptible power system, delivering 20 A rated output current. Its maintenance-free lithium iron phosphate cells bridge roughly 21 minutes at a 960 W system load, and up to five modules can be paralleled to extend backup time.

Selection Notes

Service life falls sharply with ambient temperature: 15 years at 10 C drops to 2 years at 50 C, so cabinet ventilation and mounting location drive the replacement interval more than the headline capacity rating does. At a 960 W system load the module bridges about 21 minutes; halving the load to 480 W nearly doubles that to 42 minutes, which matters when sizing a controlled-shutdown window against the actual downstream draw. Up to five BAT8600 modules can be paralleled on the same UPS8600 bus to extend runtime without changing the charger or communication wiring.
