    • Temperature sensor on battery (1 thermistor). External expansion module of up to 16 thermistors on request (as option).
    • BMS unit is protected by two temperature sensors
  • High Voltage Protection, warning and disconnects charging (2 levels warning / 1 cut off)
  • Low Voltage Protection, warning and disconnects load (3 levels warning / 2 levels cut off)
  • Starter Battery Management (SBM)
  • Charger Management System (CMS)
  • Alternator Field Disconnect (AFD)
  • Output to manage both latching (bi-stable) and non-latching contactors
  • High quality epoxy coated Circuit Board (PCB) that protects circuits in harsh and humid conditions such as marine use
  • Dimension: 205 x 120 x 39 mm (W x L x H)

BMS Control

  • Connects to MasterLi BMS
  • Warning system on Control Panel alerts in three steps with LED and buzzer before LVP or extreme battery temperature turns off battery (= blackout which shut down autopilot and all other navigation).
  • Alerts ensure that no blackout occurs suddenly and unexpectedly, which becomes a dangerous situation for boat and crew.
  • MasterLi BMS is designed with regard to boat and crew safety first in mind. For this reason, BMS has built in noise filters to avoid false triggers that could otherwise shut down the battery.
