7.8V 1.5A Charger PCB Module–Premium Power Supply Circuit Board for Fast & Efficient Charging

7.8V 1.5A Charger PCB Module is a compact, high-efficiency switched-mode power supply (SMPS) charger board designed for reliable DC power delivery and battery charging applications. Operating from a wide AC mains input, it step-downs and regulates voltage to deliver a continuous 7.8V DC output at up to 1.5A current. It is commonly utilized for charging 2S Lithium-ion/LiPo battery packs, powering specialized 7.4V/7.8V portable equipment, driving LED backup lighting systems, and serving as an embedded DC power module for custom electronic prototypes.

Features

• Switched-Mode Power Supply (SMPS) topology ensuring high efficiency and low heat generation
• Wide AC input voltage range supporting standard mains power supply grids
• Stable 7.8V DC output with low ripple and minimal voltage fluctuation under load
• Up to 1.5A continuous output current capacity for fast and efficient charging
• Built-in circuit protections against over-voltage, over-current, and output short-circuit
• Compact PCB footprint for easy integration into custom enclosures, adapters, and projects
• Pre-tinned solder pads/terminals for clean wire connections and prototyping
• High-grade electrolytic capacitors and transformer core for extended operational stability

Applications

• Dedicated charger circuit for 2S (7.4V / 8.4V series) Lithium-ion and LiPo battery packs
• Embedded power supply unit for portable LED searchlights, emergency backup lights, and audio amplifiers
• Power module for 7.8V/8V DC electronic gadgets, routers, and small consumer devices
• Microcontroller, robotics, and motor driver power regulation in student and industrial prototyping
• Polytechnic diploma and university engineering thesis projects requiring regulated DC power conversion

Important Notes:

• High Voltage Hazard: This PCB module connects directly to 100V–240V AC mains electricity. Exercise extreme caution during testing and ensure proper insulation/enclosure to prevent accidental electrical shock.
• Observe correct output polarity (+7.8V and GND) before connecting to sensitive electronic components or battery management circuits.
• Provide adequate ventilation inside the housing or project box during continuous high-load operation (1.5A).
• When charging raw multi-cell batteries, use a suitable Battery Management System (BMS) board in conjunction with this module for balanced charging.
• Do not exceed the maximum rated output current of 1.5A for prolonged periods to avoid thermal overload.

Package includes

• 1 x 7.8V 1.5A Charger PCB Module
