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. 12/24V auto-ranging The Smart BatteryProtect automatically detects system voltage one time only. 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. Note: the BatteryProtect can also be used as a charge interrupter in between a battery charger and a Li-ion battery. See the connection diagram in the manual. Ultra-low current consumption This is important in the case of Li-ion batteries, especially after low voltage shutdown. Please see our Li-ion battery datasheet and the VE. Bus BMS manual for more information. Overvoltage 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 for 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.

While this is without argument a very essential piece of equipment for certain setups such as mobile 4x4 for protection by means of a low/high voltage cut-off, I expected more functionality from the mobile app. The expectation was that the cut-off values may be adjusted in the app but the only setting is of the battery type.
The resulting problem is that my battery BMS shuts off the battery before the batter protect which means a hard reset for the batteries to reset them.

Victron Smart Battery Protect
It seems to be a great product with all the features to protectg a battery from over or under voltage.
The only problem I found was that it is a uni directional device.
I wanted to use it to protect my batteries from under voltage connected to a hybrid inverter. I was trying to find an afforable solution to protect gell batteries
