AUTORO 100A 200A ATS Dual Power Parallel Discharger Automatic Transfer Switch for RV Camper Van Boat Drone Off-Grid 12V 24V 36V

AUTORO Dual Power (Battery & DC Adapter) Parallel Discharger 50A 80A, Automatic Transfer Switch for RV Camper Van Boat Off-Grid, 12V 24V 36V 48V Dual Power Priority Selector for Load Sharing (Discharge Only)Important Operation - Wiring Connection Notice:1. First connect the negative terminal (GND).2. Then connect the two input positive terminals respectively.3. When wiring, disconnect the load first, and reconnect it after soldering.Why Autoro? 🔋【CHOOSE YOUR AMPERAGE: 50A OR 80A DUAL SOURCE DISCHARGER】Select the AB100 (50A2 channels, 40g) for medium loads or the AB200 (80A2 channels, 71g) for heavy-duty applications. This device intelligently manages two separate power sources (batteries or DC supplies) feeding a single load (Vout) . It automatically prioritizes the source with the higher voltage to discharge first. When voltages equalize, both sources discharge simultaneously, effectively doubling your runtime and available current for inverters, fridges, or trolling motors .⚡【TRUE SEAMLESS SWITCHING – ZERO DELAY FOR SENSITIVE LOADS】Experience uninterrupted power. Unlike mechanical relays or manual switches that cause a momentary dropout, this solid-state logic switch operates with zero switching delay. Keep your sensitive equipment online—ideal for CPAP machines, security cameras, GPS units, network routers, and medical devices that cannot tolerate a reboot during source switching .🚐【VERSATILE APPLICATIONS: RV, MARINE, OFF-GRID, & BACKUP LOADS】Designed for life on the move. Perfect for Vanlife conversions, Boats, Overlanding rigs, and Backup generator load circuits. The robust design with an integrated aluminum heatsink plate ensures efficient thermal management during continuous high-current discharge, whether you are drawing 50A or pushing 200A peaks .🔌【SAFE SOURCE ISOLATION & VOLTAGE COMPATIBILITY】Safety is paramount. This module isolates two input power sources to prevent dangerous short circuits or back-feeding between them, even if voltages are inconsistent (e.g., 12V vs 24V). It supports a wide voltage range (12V, 24V, 36V, 48V systems) and works with Lithium (LiFePO4), AGM, Lead-Acid, and Gel batteries as input sources .⚠️【IMPORTANT: DISCHARGE ONLY – READ BEFORE PURCHASE】This device is engineered exclusively for discharging batteries to power a load (inverter, motor, lights, etc.). It is not a battery combiner for charging. If your goal is to charge multiple batteries from one alternator or charger, this is the wrong product. If your goal is to automatically share two power sources to run your equipment seamlessly, this is the perfect solution .As a controller and ATS Source Manufacturer, distributors and partners are warmly welcome!Power Your Load Without Interruption: The AUTORO Dual Source Discharger (AB Series)Welcome to smarter load management. The AUTORO AB Series (AB100 / AB200) is the ultimate Dual Input Automatic Transfer Switch designed for enthusiasts and professionals who demand uninterrupted power for their DC loads. Whether you are combining two batteries to power a high-current inverter or creating a failsafe backup for critical equipment, this module handles the source selection logic so you don't have to.Who Needs This? (Understanding Your Use Case)The RV/Overland Traveler: You run a 12V fridge, lights, and a water pump off a house battery. You also have a starter battery. The AUTORO lets you use both batteries to power your fridge without ever draining your starter battery below starting voltage. It intelligently pulls from the highest voltage source at the moment.The Angler/Boater: Running a heavy-duty trolling motor. You need the massive amperage of two parallel marine batteries (200A peak), but you need them isolated when the motor is off to protect your engine start battery. This unit delivers seamless parallel discharge during operation.The Off-Grid Homesteader: You have a main battery bank and a secondary generator battery. The AB series automatically prioritizes the bank (higher voltage when full) and seamlessly switches to the backup if the voltage drops.The Critical Equipment User: Running a CPAP machine, security system, or network equipment off-grid. You need a backup battery to kick in instantly if the primary fails. This unit provides zero-delay failover.How It Works (The Intelligent Logic - Discharge Only)This is not a charging combiner. It is a load-sharing priority switch. The AUTORO ATS constantly monitors the voltage at Vin1 and Vin2.Priority Mode: It connects the load (Vout) to the source with the higher voltage.Parallel Mode: If both voltages are equal (both batteries fully charged), it connects both inputs to Vout, allowing them to discharge together. This doubles your available current for high-demand loads.Isolation Mode: If one source drops below the other (depleted), it instantly disconnects that input, preventing the good battery from dumping current into the dead one.Technical Confidence & Physical DesignHeat Management: Housed in a durable casing with a dedicated aluminum alloy plate, ensuring passive cooling during high-current discharge.Durability: Compact, lightweight, and solid-state—no moving parts to fail.Important Consideration: For inductive loads (motors, pumps), be aware of back EMF. Ensure total voltage (source + spike) stays within the module's rating.Choose Your Model:AUTORO AB100: 50A2 channels Continuous Discharge | 40g Weight | Recommended for Fridges, Lights, Pumps, and 1000W-1500W Inverters.AUTORO AB200: 80A2 channels Continuous Discharge | 71g Weight | Recommended for Winches, Large Trolling Motors, 2000W-3000W Inverters, and Heavy-Duty DC Loads.Important Notes:1. For loads requiring continuous high current output: The device will generate heat under sustained high current, and if the heat cannot dissipate, it will accumulate. For continuous current applications, you must leave sufficient headroom, required application:a. The AB100 continuous current ≤ 50A * 2 channels,b. The AB200continuous current ≤ 80A * 2 channels.c. Additionally, enhance external cooling conditions.2. Suitable for AGV vehicles, electric scooters, electric go‑karts, drones, etc.: These devices require a large burst of current for overtaking or acceleration, but only for a short time. The AB100 can support 100A for short bursts, and the AB200 can support 200A for short bursts. After overtaking, the current drops and the temperature will decrease.3. For loads with inverters or similar equipment: The continuous current must not be calculated solely based on the device's power rating. You must also account for the inverter's efficiency and losses. For example, if the inverter is 50% efficient, the current passing through the parallel discharger will actually be twice the current calculated from the load power.
