Semi-finishedproduct : No High-concerned chemical : none Electronic : No DIY Supplies : Electrical Brand Name : Stlxy Origin : Mainland China

Working voltage: DC 3V~30V, suitable for 3~7 series lithium batteries, 12V/24V lead-acid batteries, solar energy systems Current specifications: Available in two versions, 4A/8A, suitable for small energy storage, solar charging, and dual power parallel scenarios Circuit architecture: MOS transistors form an ideal diode, with a common ground (common ground) scheme, distinguishing isolated diode modules Core role: Prevent battery voltage from backflowing to the charging power source When the positive and negative terminals of the battery are reversed, it protects the backend equipment from being burned out Extremely low conduction voltage drop, far superior to ordinary Schottky diodes Conduction characteristics: Low conduction loss, much lower heating under high current conditions compared to traditional rectifier diodes, and higher charging efficiency Applicable scenarios: solar controller assistance, parallel charging of multiple battery groups, backup power switching, DIY lithium battery storage Wiring definition: independent pads for input and output terminals, GND common connection, simple wiring, easy system integration Protection enhancement: Built in simple over temperature protection to improve module stability under continuous heavy load conditions Operating voltage DC 3V~30V, compatible with multi-cell lithium battery, 12V/24V lead-acid battery and solar power systems. Two current options: 4A and 8A for different energy storage and charging projects. Adopt MOSFET based ideal diode circuit withcommon ground topology. Main functions: prevent battery reverse current backflow and protect devices against battery reverse polarity connection. Ultra-low forward voltage drop, much higher efficiency and less heat than conventional Schottky diodes. Ideal for solar auxiliary charging, multi-battery parallel connection and backup power switchover systems. Clear solder terminals for input, output and shared GND, easy wiring and system integration. Suitable for DIY energy storage, RV power system, outdoor solar power supply modification. label:yes
