Wide compatibility This power meter is designed for 72V battery vehicles, including lithium, polymer, and nickel metal hydride batteries. It supports a range of electric equipment requiring accurate power measurement. It is not suitable for heavyduty vehicles such as trucks and cranes. Clear dual display The meter provides a clear dual display of power and voltage. The upper color bar indicates battery power with an intuitive 8grid format (2 red, 6 green), making it easy to assess charge level at a glance. The lower voltmeter offers precise voltage readings to support accurate monitoring. Automatic identification and protection The device features automatic identification for power connections and includes reverse connection protection to safeguard against damage from incorrect wiring. Practical use scenarios Electric bicycles and light electric vehicles: monitor realtime power and voltage for 72V packs using lithium, polymer, or NiMH cells to ensure reliable operation and battery health during use. Home workshops and portable systems: manage 72V battery packs for tools, solar storage, or other equipment, enabling quick checks and safe operation. Field installation and maintenance: leverage automatic identification to reduce wiring errors and protect equipment when connecting or testing 72V power setups.
