Semi-finishedproduct : No High-concerned chemical : none Electronic : No DIY Supplies : Electrical Brand Name : Stlxy Origin : Mainland China Output Voltage : 6V

Features 1. Stable voltage boost, delivering efficient and reliable 6V output 2. Compact design for space-saving use 3. Ultra-low quiescent current, ideal for long-term standby 4. Integrated discharge, protection, and charging management 5. Rigorous performance testing ensures product stability Parameter Output Voltage: 6V Input Voltage (for battery charging): 5V Output Current: 0.5A Charging Current: 700mA MAX Boost stops when battery voltage drops below ~2.9V; full charge at ~4.2V Charging Indicator: Red light during charging, green light when full Standby Current: 10μA Precautions 1. This product is designed to boost 6V using polymer lithium batteries or 18650 lithium batteries, replacing devices powered by four AA/AAA alkaline or carbon-zinc batteries in series. Before use, confirm the positive and negative terminals of the four-battery pack. Incorrect soldering may damage the device. 2. For inductive loads like motors, ensure current demand remains well below 0.5A. Inductive loads draw extremely high inrush currents during startup. 3. Keep battery-to-module connection wires as short as possible and use copper wire. Excessive internal resistance in these wires may cause the indicator light to remain on even after the battery is fully charged. Note: If the battery capacity is too small, it may result in a cycle of charging to full capacity and stopping before the battery is fully charged. Reducing the value of resistor R4 will correspondingly decrease the maximum charging current. Package include Module*1

Work with 1S 3.7V ternary lithium battery (full charge 4.2V), adopt synchronous buck-boost topology. Stable adjustable output voltage range: 3.7V ~ 6V, perfect replacement for 4 series AAA dry batteries (nominal 6V). Integrated full lithium charge & discharge protection: over-charge, over-discharge, over-current and short-circuit lockout protection. Equipped with Type-C charging port, powered by standard 5V USB charger to recharge lithium cell conveniently. Constant stabilized output regardless of battery voltage drop; no brightness reduction or equipment shutdown when battery drains. Compact PCB design for easy modification inside original 4-slot AAA battery compartment. Ideal upgrade for remote controllers, electronic toys, mini cameras and small instruments originally powered by four AAA batteries. Eliminate frequent disposable AAA battery replacement, save long-term usage cost for consumer devices. label:yes
