Description
The 36V Two-Wire Digital Display Battery Level Indicator is a compact, highly reliable power monitoring module designed specifically for 36V lithium 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 300ms refresh rate, it is an ideal tool for monitoring electric bikes, scooters, and custom 36V 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 calculates and displays capacity based on cell multipliers (N*3.3V for 25%, N*3.5V for 50%, N*3.7V for 75%, and N*3.9V for 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.
- Fast Refresh Rate: Updates voltage and capacity telemetry every 300 milliseconds for responsive real-time monitoring.
- Ultra-Low Power Draw: Consumes only 5–15 mA of operating current, minimizing any parasitic drain on the tested battery pack.
Benefits
- Instant Visual Health Checks: Quickly gauge your 36V battery’s remaining energy at a glance without needing a separate multimeter.
- Foolproof Protection: Reverse polarity safeguards the unit against accidental wiring mistakes during dashboard integration.
- Lightweight & Compact Footprint: Tiny module form factor fits seamlessly into tight project enclosures, custom electric vehicle dashes, and portable gear.
- Wide Temperature Tolerance: Engineered to operate reliably in harsh environments ranging from -20°C up to 65°C.
Applications
- Electric Vehicles & E-Bikes: Real-time battery level tracking for 36V electric scooters, bikes, and light EVs.
- Custom Lithium Battery Packs: Power level monitoring for custom-built 36V multi-cell battery assemblies.
- Maker & Prototyping Projects: Compact voltage indicator for high-voltage DC test rigs and experimental setups.
- Industrial & Utility Equipment: Simple power status monitoring for portable backup devices running on 36V architecture.
