It disconnects the load before the battery reaches a critically low voltage, preventing cell damage and extending battery service life. It is suited to off-grid solar systems, marine installations, and any 48V DC application where load shedding is required.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eRated at 100A continuous current on a 48V system, suitable for substantial DC load circuits.\u003c\/li\u003e\n  \u003cli\u003eAutomatic disconnect on low battery voltage with configurable reconnect threshold, protecting cells from deep discharge damage.\u003c\/li\u003e\n  \u003cli\u003eExtremely low self-consumption, minimising parasitic drain on the battery bank when idle.\u003c\/li\u003e\n  \u003cli\u003eRemote on\/off input allows integration with battery management systems, inverters or manual switches.\u003c\/li\u003e\n  \u003cli\u003eAlarm output provides a pre-disconnect warning signal, allowing loads or systems to shut down in a controlled manner before isolation occurs.\u003c\/li\u003e\n  \u003cli\u003eCompatible with lithium (LiFePO4) and lead-acid battery chemistries, with voltage thresholds selectable via a rotary switch.\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight design at 0.8 kg, suitable for panel or DIN rail mounting in enclosures.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe BatteryProtect works by monitoring battery voltage continuously. When voltage drops to the programmed disconnect threshold, the unit opens the load circuit and holds it open until the battery recovers to the reconnect voltage. This prevents the sustained low-voltage conditions that cause irreversible capacity loss in both lead-acid and lithium cells. The rotary switch on the unit allows the installer to select from several pre-set voltage profiles without any additional programming tools.\u003c\/p\u003e\n\n\u003cp\u003eThe remote input accepts a signal from an external source such as a Victron BMV battery monitor, a BMS, or a simple switch. This allows the BatteryProtect to be overridden or controlled as part of a wider system. The alarm output can drive an LED indicator or feed a signal to a monitoring system, giving advance notice before the full disconnect occurs. These features make it straightforward to integrate into both simple and more complex off-grid or marine DC systems.\u003c\/p\u003e\n\n\u003cp\u003eAt 100A, this unit covers a wide range of 48V load scenarios including inverter pre-loads, DC distribution boards, and auxiliary circuits. It is not a charge controller and should be wired on the load side of the battery, not between the battery and charger.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"border: 2px solid #f87c24; border-collapse: collapse; width: 100%;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color: #f87c24; color: #ffffff;\"\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eValue\u003c\/strong\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eSKU\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eBPR048100400\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eSystem Voltage\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e48V DC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eContinuous Current Rating\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e100A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eWeight\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e0.8 kg\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eGTIN\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e8719076021469\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eOff-grid solar systems with 48V battery banks requiring automatic load disconnect on low voltage.\u003c\/li\u003e\n  \u003cli\u003eMarine and narrowboat DC systems where battery protection is required on auxiliary load circuits.\u003c\/li\u003e\n  \u003cli\u003eMotorhome and vehicle conversions running 48V DC distribution.\u003c\/li\u003e\n  \u003cli\u003eTelecom and remote monitoring installations with 48V battery backup.\u003c\/li\u003e\n  \u003cli\u003eAny 48V DC system where preventing battery over-discharge is a design requirement.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Victron BatteryProtect 48V-100A (BPR048100400)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe BatteryProtect must be installed on the load side of the battery, between the battery bank and the DC loads.

Installation in 48V systems should be carried out by a qualified electrician or experienced system integrator familiar with DC battery systems. For systems connected to solar PV or grid-tied equipment, ensure all relevant wiring regulations and local compliance requirements are observed.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":47486575313230,"sku":"BPR048100400","price":87.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/victron-batteryprotect-48v-100a-bpr048100400-488352.jpg?v=1747941788","url":"https:\/\/voltaconsolar.com\/products\/victron-batteryprotect-48v-100a","provider":"VoltaconSolar","version":"1.0","type":"link"}
