"Protect your batteries: Battery Protect from Victron disconnects non-essential loads automatically."
Victron Energy's BatteryProtect automatically disconnects non-essential consumers from the battery before it is completely discharged (and damaged), or before it is too discharged to start the engine.
BatteryProtect can be configured to activate/deactivate at different voltage levels. The 7-segment display indicates which configuration has been chosen.
Special configuration for lithium-ion batteries
In this mode, the BatteryProtect can be controlled by the VE-Bus BMS.
Very low energy consumption
This is an important feature for lithium-ion batteries, especially after a low-voltage stop.
Please consult our lithium-ion battery data sheet and the VE.Bus BMS manual for more information.
Protection against overvoltage and combustion
> To protect sensitive equipment from overvoltage, the load is automatically disconnected when DC voltage exceeds 16 V or 32 V.
> To protect devices against combustion: no relays, but MOSFET transistors, so there's no sparking.
Delayed alarm output
The alarm output is activated if the battery voltage drops below the preset disconnection level for more than 12 seconds. Starting the motor will therefore not activate the alarm. The alarm output is a short-circuit-proof open-collector output connected to the rail (negative), maximum current 50 mA. The alarm output is generally used to activate a buzzer, LED or relay.
Load disconnection and reconnection times
The load will be disconnected 90 seconds after the alarm is activated. If the battery voltage rises again to the connection threshold during this period (when the motor has been started, for example), the load will not be disconnected.
The load will be reconnected 30 seconds after the battery voltage exceeds the preset load reconnection voltage.
