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.

When using Bluetooth to program the Smart BatteryProtect any required engage/disengage levels can be set. Alternatively one of nine predefined engage/disengage levels can be set with the programming pin (see manual). If required Bluetooth can be disabled.

The Smart BatteryProtect is not designed for reverse currents from charging sources.

Features

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.

Bluetooth: programming made easy: When using Bluetooth to program the Smart BatteryProtect any required engage/disengage levels can be set. Alternatively one of nine predefined engage/disengage levels can be set with the programming pin (see manual). If required Bluetooth can be disabled.

A special setting for Li-ion batteries: In this mode the BatteryProtect can be controlled by the VE.Bus BMS

Ultra-low current consumption: This is important in case of Li-ion batteries especially after low voltage shutdown. 

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: The 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. The alarm output is typically used to activate a buzzer LED or relay.

Delayed load disconnect and delayed reconnect: 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. The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage.
