Key benefits Instant, easy-to-read battery status: a clear dual display shows both remaining power and exact voltage so you can make timely charging or usage decisions. Broad vehicle and battery compatibility: works across a wide 12V–72V range and with common battery chemistries, reducing the need for multiple meters. Reliable measurements for everyday and light-duty electric vehicles and battery systems; not designed for heavy industrial loads. What it does and why it helps Monitors battery charge level and voltage in one unit so you can prevent unexpected power loss and plan maintenance. Supports power measurement tasks to help you track battery performance and detect issues early. Automatic voltmeter decimal shifting improves readability and accuracy at different voltage levels. Key features Voltage range: compatible with 12V–72V battery systems. Dual display: Upper 8-segment color bar shows battery power (2 red segments, 6 green segments). Lower digital voltmeter shows battery voltage with automatic decimal-point shifting. Battery chemistries supported: lithium, polymer, nickel‑metal hydride, lead‑acid, car batteries and other electric vehicle batteries. Intended use: passenger and light electric vehicles and battery systems; not suitable for high-performance or heavy-duty vehicles such as large trucks, cranes, and forklifts. Practical applications (real-world scenarios) Electric bicycles and scooters: keep track of remaining range and voltage on each ride to avoid being stranded. Small electric vehicles and golf carts (within 12V–72V): monitor battery condition for daily use and charging decisions. Battery testing and maintenance: use as a quick power/voltage check for lithium packs, lead‑acid batteries, car batteries or other light EV battery systems during service or troubleshooting. Notes and limitations Designed for measurement and monitoring of light-duty battery systems. Do not use for high-current, heavy-duty industrial equipment. Follows the original voltage range and supported battery types; check your vehicle/battery voltage and chemistry before installing.
