It suits off-grid installers, marine electricians and commercial integrators who need programmable battery protection without a full battery management system handling load shedding.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous current\u003c\/strong\u003e, rated for 48V systems at 100A, suited to substantial DC load circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth control\u003c\/strong\u003e, configure thresholds and monitor status wirelessly through the VictronConnect app.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProgrammable thresholds\u003c\/strong\u003e, low-voltage disconnect and reconnect points can be set for lead-acid, AGM, gel or lithium chemistries.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOver-voltage disconnect\u003c\/strong\u003e, protects downstream loads from voltage spikes during charging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReconnect logic\u003c\/strong\u003e, the unit waits for the battery to recover to the set reconnect voltage before restoring the load, preventing rapid cycling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemote on\/off input\u003c\/strong\u003e, allows integration with external control signals, including other Victron system components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e, 0.8 kg.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct overview\u003c\/h2\u003e\u003cp\u003eThe unit monitors battery voltage continuously and disconnects the load circuit once voltage falls below the programmed threshold, preventing deep discharge events that shorten battery life. For lithium batteries it adds a hardware-level layer of protection alongside the battery's own BMS.\u003c\/p\u003e\u003cp\u003eConfiguration is done through VictronConnect over Bluetooth rather than physical DIP switches or a display, which suits enclosed installations such as under-floor battery compartments, marine bilge areas or cabinet-mounted off-grid systems. The over-voltage disconnect responds if a charger or solar charge controller pushes voltage above safe limits, opening the load circuit to protect connected inverters and converters.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOff-grid solar systems needing automatic load disconnection before damaging discharge levels are reached.\u003c\/li\u003e\n\u003cli\u003eMarine and narrowboat installations requiring load shedding to protect the house battery bank.\u003c\/li\u003e\n\u003cli\u003eMotorhome and campervan builds with 48V lithium or lead-acid leisure batteries.\u003c\/li\u003e\n\u003cli\u003eTelecom and remote monitoring sites where battery longevity matters and visits are infrequent.\u003c\/li\u003e\n\u003cli\u003eCommercial cabinets where Bluetooth commissioning avoids the need for physical access.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eFit the Smart BatteryProtect in the load circuit only, between battery and loads, never in series with a charger output. On 48V lithium systems, installation should be carried out by a qualified electrician. Cabling must be rated for the full 100A continuous current, with appropriate fusing on the battery side per wiring regulations. Configuration requires a Bluetooth-enabled device running VictronConnect.\u003c\/p\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1 x Victron Smart BatteryProtect 48V-100A (BPR110048000)\u003c\/li\u003e\u003c\/ul\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":52060753527072,"sku":"BPR110048000","price":118.64,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-bpr110048000-1.webp?v=1785503627","url":"https:\/\/www.ledandsolar.co.uk\/products\/smart-batteryprotect-48v-100a","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
