Victron Smart BatteryProtect 220 A 12 V/24 V with inbuilt Bluetooth protects batteries and connected appliances by avoiding deep discharge and overvoltage.

• Low voltage disconnect: when battery charge is low, the Smart BatteryProtect disconnects non‑essential loads to avoid deep discharge and preserve battery health; programmable low‑voltage threshold for customised disconnect settings.
• Overvoltage disconnect: disconnects loads if battery voltage becomes too high to protect equipment; Bluetooth connectivity for easy smartphone programming; automatic system recognition (detects 12 V or 24 V on start‑up).
• Ultra‑low current consumption to avoid additional battery drain, especially after a low‑voltage disconnect; remote switch and alarm connections allow input/output relay control and external alarms.
• Compatible with lithium batteries: specialised modes for use with Ve.Bus Lithium battery management systems and as a charge interrupter for lithium charging.
• System specifications: nominal battery voltage 12 V / 24 V; operating voltage range 6–35 V; maximum continuous current 220 A; peak current (30 seconds) 600 A.
• Electrical & safety: current draw <1.5 mA active, <0.6 mA during disconnect; alarm relay 50 mA.
• Dimensions & environment: dimensions 62 x 123 x 120 mm (2.44 x 4.84 x 4.72 in); weight 800 g (1.76 lb); M8 terminals; operating temperature range -40°C to +40°C (-40°F to 104°F) — up to 60% capacity at 50°C (122°F).
• Additional items: negative cable 50 cm length, 1.5 mm² cross section; 2‑pin dry‑contact socket for remote switch. Documents available: User manual for Victron Smart Battery Protect 220 A 12/24 V (VE‑SBPR220) and product datasheet.

Please note: the Smart BatteryProtect must be connected on the positive battery wire, close to the battery. If you need installation help or technical support we can provide guidance and programming assistance.
