Features high-current handling and precision voltage sensing for RV, marine, and off-grid solar applications.", "brand": { "@type": "Brand", "name": "Solarika" }, "sku": "BBR-300", "mpn": "BBR-300", "offers": { "@type": "Offer", "url": "https://Solarika.co.uk/products/{{ product.handle }}", "priceCurrency": "GBP", "price": "{{ product.price | money_without_currency }}", "availability": "https://schema.org/InStock" } } Solarika BBR-300 Battery Relay High-Current 300A Bi-Directional Split Charge Isolator The Solarika BBR-300 is a heavy-duty 12V battery booster and isolation relay engineered for demanding dual-battery environments. Whether you are managing a winch, a high-output inverter, or a split-charging leisure battery system in a motorhome or boat, the BBR-300 provides seamless power management without the voltage drop associated with traditional diode isolators. RELIABILITY: Built to meet or exceed OEM specifications with silver alloy contacts and an IP65-rated housing for long-lasting performance in harsh environments. Key Features ✔ 300A Continuous handling capacity ✔ Bi-Directional Sensing for dual charging ✔ Zero Voltage Drop mechanical switching ✔ IP65 Weatherproof sealed construction ✔ Surge protected electronics Technical Specs Nominal Voltage 12V DC Continuous Current 300A Peak Current (Surge) 1000A Engage Voltage 13.3V DC Disengage Voltage 12.8V DC Terminals M8 Stainless Studs Compatibility / Fitment Guide Application System Type Notes Marine / Boats 12V Outboard/Inboard Corrosion resistant terminals. RV / Motorhomes Split Charge System Ideal for T4/T5/T6 and Sprinters. Solar Off-Grid Battery Bank Isolation Supports Bi-Directional solar charging. OEM Cross Reference Manufacturer Part Number Reference RV Custom Products EB300 Intellitec (Equiv) 00-00507-000 / 00-00507-512 KeyLine Chargers VSR-300-PRO Installation Guide Mount the relay as close as possible to the primary battery. Connect the primary battery to the "Main" stud and the auxiliary battery to the "Aux" stud. Ensure a solid ground connection for the sensing wire. For 300A loads, use minimum 50mm² (0AWG) copper cabling to prevent overheating. Professional installation is heavily recommended. Questions & Answers Is this a genuine original part? This is a premium Solarika high-current replacement part, manufactured to meet or exceed original equipment (OE) standards for heavy-duty power management. How do I know if it is compatible? Check your current relay's amperage and voltage. If you require a 12V system with a draw up to 300A continuous, the BBR-300 is the correct high-performance upgrade. Can this relay be used with Lithium (LiFePO4) batteries? Yes. Because it is a mechanical relay with bi-directional sensing, it will work with Lithium banks provided your charging source (alternator/solar) is regulated for Lithium voltages. Note: Please verify your original part number and system amperage requirements against the references above before purchasing. Distributed by Solarika.co.uk.
