Description
The 13V Two-Wire Digital Display Battery Level Indicator is a compact, highly reliable power monitoring module designed specifically for 12V/13V lithium and DC battery systems. Featuring a vivid display with a striking red outline and bright blue LED status blocks, this meter provides real-time visual feedback on your battery’s remaining charge across four distinct capacity tiers (25%, 50%, 75%, and 100% full).
Installation is effortless: simply connect the red wire to the positive pole and the black wire to the negative pole of your power source. Built-in reverse polarity protection ensures the circuit remains completely safe even if the wires are accidentally mismatched. Drawing minimal operating current with a fast refresh rate, it is an ideal tool for monitoring 12V portable power boxes, backup systems, and custom DC battery packs.
Note: Product design or physical appearance may vary slightly based on manufacturing batches. No additional external power supply is required.
Key Features
- 4-Tier Voltage Threshold Display: Dynamically indicates capacity based on precise voltage levels (L1: 11.0V = 25%, L2: 11.6V = 50%, L3: 12.3V = 75%, L4: 13.0V = 100% full capacity).
- Simple Two-Wire Hookup: Direct connection layout with a red positive wire and black negative wire for quick and hassle-free installation.
- Reverse Polarity Protection: Smart internal circuit design prevents permanent burnout if wires are accidentally cross-connected during setup.
- Vibrant Dual-Color Display: Features a sharp red outline frame framing bright blue LED status blocks that fully illuminate when the battery is fully charged.
- Ultra-Low Power Draw: Minimal operating current minimizes any parasitic drain on the tested battery pack.
Benefits
- Instant Visual Health Checks: Quickly gauge your 12V/13V battery’s remaining energy at a glance without needing a separate multimeter.
- Foolproof Protection: Reverse polarity safeguards the unit against accidental wiring mistakes during panel integration.
- Lightweight & Compact Footprint: Tiny module form factor fits seamlessly into tight project enclosures, custom power boxes, and portable gear.
Applications
- 12V Power Banks & Solar Boxes: Real-time battery level tracking for custom 12V lithium generator boxes and portable power stations.
- Automotive & Marine Auxiliary Packs: Power level monitoring for secondary 12V accessory batteries and lighting setups.
- Maker & Prototyping Projects: Compact voltage indicator for DC test rigs, hobbyist electronics, and experimental setups.
- Emergency Backup Systems: Simple power status monitoring for small 12V UPS and backup power supplies.
