Victron Energy Smart Battery Protect 48V/100A

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

Features of the - Victron Energy Smart Battery Protect 48V 100A

Protects the battery against excessive discharge and can be used as a system on/off switch

The Smart Battery Protect 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 Battery Protect 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 Battery Protect 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. 

Please see our Li-ion battery datasheet and the VE.Bus BMS manual for more information. 

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 pre-set 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 pre-set 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 pre-set reconnect voltage.
