2. Features
The Smart BatteryProtect offers a wide range of different features. These include:
Protection of the battery against excessive discharge and can be used as a system on/off switch.
12/24V auto ranging. The Smart BatteryProtect automatically detects system voltage one time only (can be re-triggered - see section Programming table).
Easy Bluetooth programming.
A special setting for Lithium batteries. This feature allows external control from a BMS like the VE.Bus BMS or Lynx Smart BMS. If the load disconnect output of a BMS is connected to the Remote H input and the signal becomes free-floating, the load is immediately disconnected.
Ultra-low current consumption of 1.4mA with Bluetooth on: This is important in case of Li-ion batteries, especially after low cell 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 (for a 12V system), respectively 32.6V (for a 24V system).
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.
Delayed load disconnect and delayed reconnect. Responding quickly within this delay, for example, by reducing the load or starting a generator or charger to charge the batteries, can prevent loads from being switched off.
