Victron Smart BatteryProtect 48V-100A

<p>The Smart BatteryProtect 48 V 100 A is designed to protect 48 V battery systems from excessive discharge and damaging voltage conditions. It automatically disconnects non-essential loads when the battery voltage drops below a preset level, preventing deep discharge and extending battery life.</p>
<p>Using built-in Bluetooth, the unit can be easily programmed via a mobile device to set custom connect and disconnect thresholds. It can also function as a remote system on/off switch and integrates with battery management systems (BMS), making it ideal for lithium battery applications and professional energy storage installations.</p>
<p>With ultra-low power consumption, solid-state MOSFET switching (no relays), and built-in alarm output, the Smart BatteryProtect offers reliable, spark-free operation for demanding DC environments such as solar, telecom, and off-grid systems.</p>
