Description
The 1S Li-Po Lithium Battery Capacity Indicator Module is a compact, highly reliable power monitoring display designed to provide intuitive, real-time voltage and charge status for single-cell lithium systems. Featuring a striking red outline frame and bright blue LED display blocks, this meter makes monitoring your power reserves effortless across single-cell lithium-ion packs, 18650 cells, polymer lithium batteries, and small portable DC electronics.
Installation is completely plug-and-play: simply connect the positive and negative terminals of the display board to the corresponding terminals of the battery under test. Built-in reverse polarity protection ensures the circuit remains fully safe even if the wires are accidentally mismatched. Its ultra-lightweight, slim profile makes it an ideal addition to DIY 3.7V power boxes, portable test gear, and custom single-cell builds.
Note: Actual product design or component layout may vary slightly based on manufacturing stock availability. No external power supply required—operates directly off the tested power source.
Key Features
- Single-Cell Lithium Optimization: Tailored specifically for 1S (3.7V nominal / up to 4.2V fully charged) lithium-ion, LiPo, and 18650 cell monitoring.
- Reverse Polarity Protection: Smart internal circuit design prevents permanent damage if the positive and negative wires are accidentally crossed.
- Vibrant Dual-Color Digital Display: Features a sharp red outline framing bright blue LED blocks that fully illuminate when the battery capacity is at maximum charge.
- Real-Time Telemetry: Automatically displays live battery capacity and voltage metrics the moment it is connected.
- Ultra-Lightweight Form Factor: Weighing only ~3 grams with a compact 41 × 20 mm footprint, it integrates seamlessly into tight custom enclosures.
Benefits
- Instant Visual Capacity Checks: Quickly gauge your 1S battery’s remaining energy at a glance without pulling out a separate digital multimeter.
- Foolproof Installation: Reverse connection safety prevents accidental burnout during hobbyist wiring and panel builds.
- Zero Standby Complications: Direct two-wire hookup means you monitor power on-demand simply by tapping into the circuit.
Applications
- Single-Cell DIY Power Banks: Status display panel for custom 3.7V portable lithium power boxes and mini USB chargers.
- Portable Electronics & Gadgets: Battery level tracking for handheld DIY instruments, wearable projects, and small DC projects.
- 18650 Battery Holders: Integrated power gauge for custom single 18650 battery compartments and project boxes.
