F Additional functions
System Present function
The use of this function is mandatory for the use of the battery. To enable the main current path, pin 6 (SP0)
must be bridged to pin 8 (GND) on the communication connector. Otherwise, the BMS permanently blocks the
main MOSFET switch.
Note:
In case of a failure, the MOSFET main switch is not enabled despite activated Syste Present function.
G Operation modes
The BP-LFP-2725 has a switch on the cable side of the pack near the cable outlets. This switch has three modes:
UPSI, UPSI, OFF. These different switch positions are printed on the label next to the switch:
