Newmar 2-3-70 Battery Isolators2-3-70 Battery IsolatorThis heavy-duty isolator allows charging multiple batteries automatically from one or two alternators and prevents the discharge or ‘dumping” of one battery into another. Each battery is charged according to its need without overcharging and is rated for 12-, 24-, or 36-volt negative ground DC systems. Features: Conservatively rated diodes and a rustproof anodized aluminum heat sink case. Heavy-duty construction Rated for systems up to 48 volts DC, negative ground Rust-proof anodized aluminum case Stainless steel mounting hardware is provided Protective covers are provided for terminals Specifications: Alternator Sources: 2 Battery Bank: 3     Max. Amperage Input Capacity: 70 Stud Terminal Size: 6mm     Dimensions (L x W x H): 6.5 x 4.5 x 3.1 inches Weight: 4 lbs. Operating Temperature: -40 to +80 degrees Duty Cycle: Continuous rating to 50 degrees C Derate linearly to 70% @ 80 degrees C. Temp. Rise: 5 degrees C at full rated current (mount vertically for optimum cooling) Voltage Drop: 0.7V @ 50% load, 0.9V @ full load *Note: These battery isolators are not compatible with self-exciting alternators. The alternator must have an external excitation lead. Please consult the manufacturer of your alternator if you are unsure of your configurationThis product may not be returned to the original point of purchase. Please contact the manufacturer directly with any issues or concerns. Normalized SKU: 2370

Battleborn LI-BIM Battery Isolators The LiFePO4 Battery Isolation Manager (BIM) monitors voltage and connects batteries when needed. Under normal charging conditions, the BIM will connect for 15 minutes every 35 minutes. That means that the BIM will connect for 15 minutes, disconnect for 20 minutes, and repeat this cycle until the coach battery is charged. If the coach battery resting voltage exceeds 13.4 V then the BIM will disconnect. A resting voltage greater than 13.4 V indicates a fully charged battery. Note that “resting voltage” means that no current is flowing to the coach battery. The BIM will disconnect if the alternator voltage exceeds 14.4 V. This protects the coach battery from overcharging. The LiFePO4 Battery Isolation Manager will disconnect if the voltage difference between the alternator and the coach battery is less than 0.1 V. If the voltage difference is too low, then there is a negligible charging current, and no need to connect to the coach battery. The BIM will disconnect if the alternator voltage drops below 13.3 volts. If the alternator voltage is too low, then it cannot adequately charge the coach battery, so there is no reason to connect.

Wirthco 20092 Battery IsolatorsAlso sold as Battery DoctorOur new state-of-the-art, fully automatic dual battery controller is suitable for any vehicle with an auxiliary battery. Smaller and lighter than other standard battery isolators, the Battery Doctor Battery Isolator employs electronic switching control technology. Our high-performance electronic isolator allows you to charge two batteries from a single alternator, and keeps the starting battery isolated from the second battery. Also, with a single push of the override/reset button, you can change the batteries to parallel mode for jump starting. Includes mounting bracket that houses the 4" x 4" x 2" Isolator. Amperage: 150 Amp. Voltage: 12 Volt. Charging Type: Parallel. Control: Electric. Approval: EMC. Current Draw: Charging 50 mA/(Standby 30 mA). Surge Protection: Built-In. Mounting: Surface/Fire Wall/Battery Side. Voltage Draw: None. Water resistant – suitable for marine use (IP62) Priority charging for starting battery Over current and surge protected for vehicles with electronic systems Manual override for starting battery Automatically charges auxiliary battery Normalized SKU: 20092UPC Code: 010054200929

Vanner 51-140 Battery Isolators Vanner's battery isolators allow dual batteries to be charged from a single power source such as an alternator or battery charger. It separates two battery banks during discharge and combines both banks when charging. 1 Alternator 2 Bank 250A Max Alternator 200 Amps Max per Leg 2.5" x 4.5" 8" Vanner battery isolators allow dual batteries to be charged from a single power source such as an alternator or battery charger. Due to the isolator's ability to pass current in only one direction, your first battery can be discharged without draining power from the second battery. For example, a typical vehicle system may use one battery dedicated to the engine (starter, ignition, etc.) And the other battery dedicated to a DC to AC inverter. With the engine running, the alternator will supply charging current to both batteries. With the engine off, the DC to AC inverter could continue to operate, discharging the second battery. With a battery isolator operating in the system, the power would not be taken from the engine's battery, keeping it fully charged. Vanner manufactures both silicon and Schottky type battery isolators. Both types utilize a special heat sink design for excellent heat dissipation and heavy-duty wiring terminals. Schottky battery isolators are designed to reduce the voltage drop across the isolator's terminals, allowing a higher voltage, or charge, to be delivered to the battery. This is desirable in many vehicles where more power is required, and is mandated on ambulances that must meet the GSA'™s specification KKK-1822-D. Vanner battery isolators operate on both 12 and 24 volt DC electrical systems. As current passes through an isolator, the diode type affects the voltage loss across it. A Schottky diode reduces the loss by one-half of a typical silicon diode To prevent voltage spikes and surges caused by turning the battery switch off while the engine is running, please follow the GSA recommended wiring diagram on the reverse side. Vanner model 52-75 has been designed to meet the requirements for the 12 Vdc medical outlets stated in section 3.7.7.3 of the GSA specification KKK-A-1822D. Normalized SKU: 51140
