Victron Energy Smart BatteryProtect - 6-35V DC

Victron Energy's 6-35V DC Smart BatteryProtect protects the battery against excessive discharge and can be used as a system on/off switch. The Smart BatteryProtect disconnects the battery from non-essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine. The on/off input can be used as a system on/off switch.

Features:

• Automatically detects system voltage - 12/24V auto ranging
• Programming made easy when using Bluetooth to program the Smart BatteryProtect any required engage/disengage levels can be set
• A special setting for Li-ion batteries - in this mode the BatteryProtect can be controlled by the VE.Bus BMS
• Ultra-low current consumption
• Over voltage protection to prevent damage to sensitive loads due to over voltage, the load is disconnected whenever the DC voltage exceeds 16.3V respectively 32.6V
• Ignition proof no relays but MOSFET switches, and therefore no sparks
• Delayed alarm output is activated if the battery voltage drops below the preset disconnect level during more than 12 seconds
  • Starting the engine will therefore not activate the alarm
  • The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA
  • Alarm output is typically used to activate a buzzer, LED or relay
• The load will be disconnected 90 seconds after the battery voltage drops below the preset level
  • If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), the load will not be disconnected
