bi borro Battery Isolator (12 V / 24 V) Key benefits Reliable battery management: Controls the interaction between primary and secondary batteries to prevent unwanted discharge while allowing controlled power sharing when needed. Better start and backup power: Can draw from the secondary battery to help start the engine or maintain electrical load in demanding situations. Broad compatibility: Works with 12 V and 24 V systems used in RVs, SUVs, boats, yachts, cars and other multi-battery setups. Safe and compact: Built from high‑strength metal with a low‑heat design for safer operation; compact form factor fits into tight installation spaces. Visual status feedback: Intelligent LED indicator provides clear, real‑time information about charge and discharge states. What it does and why you need it Prevents the starter battery from being drained by auxiliary loads while still enabling the auxiliary (house) battery to supply power when required. This reduces the risk of a no‑start condition and improves overall system reliability. Offers dependable performance when extra current is required — ideal for situations where accessories, winches, fridges or other loads can otherwise deplete a single battery. Designed to integrate with battery management systems, including our Battery Manager, helping maintain safe charging and discharge behavior across batteries. Key features Voltage compatibility: 12 V and 24 V battery systems. Vehicle compatibility: RVs, motorhomes, SUVs, boats, yachts, cars and other multi-battery installations. Construction: High‑strength metal housing for durability and reduced heat generation. Size and installation: Compact structure suited for installation in confined spaces without compromising performance. Indicator: LED intelligent blinking to show charging/discharging/isolated states for quick diagnostics. Practical applications RV camping: Keep house batteries available to run appliances while ensuring the starter battery remains isolated and ready to start the engine. Boating: Provide reliable backup power to start the engine or support navigation/electronics when the main battery is drained. Overlanding and towing: Allow auxiliary batteries to support high-draw accessories (winches, fridges, lighting) while protecting the vehicle’s starter battery. Technical summary Model: bi borro Battery Isolator Voltage: 12 V / 24 V compatible Material: High‑strength metal housing Indicators: LED for charge/discharge status Designed for integration with battery management systems Order this isolator when you need robust battery isolation, compact installation, clear status indication, and the ability to safely share power between batteries in a variety of 12 V and 24 V vehicles and systems.
