  • Page 19: Lynx Distributor Settings

    Lynx Smart BMS The discharge floor prevents full discharge and should be chosen so that there is enough energy to keep the Lynx Smart BMS powered for 24 hours to provide sufficient time to recharge the battery. If the battery is not recharged after the discharge floor has been reached, the battery will continue to be discharged through self consumption until a low cell voltage event occurs, at which point the Lynx Smart BMS will go into OFF mode with a delay of 2 hours to prevent deep discharge.
