3.7V 1S Lithium Battery Capacity Indicator Module Blue Display

The 3.7V 1S Lithium Battery Capacity Indicator Module is a highly reliable, easy-to-read visual monitor for your portable power setups. Designed specifically for single-cell (1S) 3.7V Lithium-ion or LiPo batteries, this module features a bright blue LED display that instantly shows the remaining charge level in intuitive bars. It accurately measures up to the 4.2V fully charged state, taking the guesswork out of your power management. If you need to buy online in India for a quick weekend build or an ongoing engineering project, this compact indicator is an essential addition to keep your electronics running safely.

This battery level indicator is widely compatible with custom DIY power banks, RC drones, robotics chassis, and IoT devices built around microcontrollers like Arduino or ESP32. With its ultra-compact form factor and simple two-wire connection, you do not need a complex circuit diagram or extensive coding to integrate it. Simply wire it in parallel with your battery output to get real-time visual feedback on your system's power status.

Features:

• Accurate Voltage Tracking: Calibrated specifically for 1S 3.7V lithium cells, scaling accurately up to a 4.2V fully charged state.
• Vibrant Blue Display: Features a clear, bright blue LED battery icon with 4 segmented bars to indicate percentage levels.
• Easy Integration: Simple positive and negative solder pads for quick, hassle-free installation into any circuit.
• Ultra-Compact Design: Small PCB footprint ensures it fits easily into tight RC chassis or custom 3D printed enclosures.
• Low Power Consumption: Draws minimal current, ensuring it does not drain the battery it is meant to monitor.
