SD05CRMA Mini Solar Lithium Battery Charger Module

The SD05CRMA Solar Lithium Battery Charger Module is a compact and highly efficient charge controller designed for portable DIY electronics. Utilizing an advanced charging IC, it allows you to safely charge single-cell 3.7V lithium-ion or lithium-polymer batteries directly from a 5V solar panel or a standard USB power supply. It is perfect for developing off-grid power solutions and renewable energy projects with minimal external components.

This module is incredibly versatile and widely used in remote IoT sensor nodes, solar-powered smart garden lights, and weather stations. When you buy online in India, you receive a reliable charging solution that easily integrates with standard 18650 cells and miniature solar setups. The onboard status LEDs provide immediate visual feedback for the charging state and completion, simplifying your circuit diagram and streamlining the troubleshooting process.

Features:

• Solar Optimized: Specifically designed to draw power efficiently from standard 5V or 6V mini solar panels.
• Battery Compatibility: Safely charges standard single-cell 3.7V Li-ion and Li-Po batteries (4.2V fully charged threshold).
• Status Indicators: Features onboard 'CR' (Charging) and 'OK' (Fully Charged) LEDs for real-time visual monitoring.
• Compact Design: Ultra-small footprint allows for effortless integration into space-constrained 3D printed projects and waterproof enclosures.
• Safe Charging Logic: Includes built-in constant-current/constant-voltage (CC/CV) charging profiles to maximize battery lifespan and performance.
