Multiconnector pin-out and overview Page 44 Appendix Description default value adjustable fixed automatic Battery capacity 200Ah Yes No No Charged voltage 14.0V/28.0V/56.0V* Yes No No Tail current 4% Yes No No Zero current calibration --- No No Yes (at power up) Peukert exponent 1.05 No Yes No Charge efficiency factor 99% No Yes No Current threshold 0.05A No Yes No Low SoC warning level 15% Yes No No Discharge floor 10% Yes No No Delta T 1 No Yes No SoC Cycle end 90% No Yes No SoC Cycle 65% No Yes No SoC full discharge 5% No Yes No Pin Name Type Function 1 AUX voltage output + System voltage positive The positive connection to power auxiliary devices, like a GX device.
2 AUX voltage output - System voltage negative The negative (ground) connection to power auxiliary devices, like a GX device. 3 Allow to charge Potential free Turns chargers on or off via a wired signal. Pin 3 can be used as the 4 contact signal input for pin 4 and wired e. g. from AUX + or AUX -. See system examples for correct wiring. When charging is allowed, the contacts are closed and when not allowed, the contacts are open. 5 Allow to discharge Potential free Turns loads on or off via a wired signal. Pin 5 can be used as the 6 contact signal input for pin 6 and wired, e. g. from AUX + or AUX -. See system examples for correct wiring.
When discharging is allowed, the contacts are closed and when not allowed, the contacts are open. 7 Programmable relay NC Potential free contact 8 Programmable relay COM Potential free contact The programmable relay is used to either control an alternator or as an alarm relay. For details, see chapter Programmable relay wiring [12]. 9 Programmable relay NO Potential free contact 10 Remote on/off H Pull-up resistor To remotely turn the Lynx Smart BMS on or off. For full functionality, see chapter Wiring the Remote on/off [12].
