This voltmeter is fully compatible with lithium, polymer, nickel-metal hydride, and lead-acid battery packs. It works across a broad voltage range — 12V, 24V, 36V, 48V, 60V, 72V, and 84V — depending on the model variant you select. Simply connect the two wires directly to your battery terminals for an instant reading.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What does the dual display show?\u003c\/h4\u003e\n\u003cp\u003eA: The upper section features an 8-bar LED graph displaying the estimated remaining charge level (from 10% to 100%), while the lower section shows the exact real-time voltage reading with decimal precision. This makes it easy to monitor battery status at a glance on electric bikes, scooters, cars, and DIY power projects.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does this voltmeter have reverse connection protection?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The meter includes built-in reverse connection protection, meaning accidental reverse wiring will not damage the unit. It's a simple two-wire system — just connect and read, no additional power source or complex wiring required.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the mounting size for panel installation?\u003c\/h4\u003e\n\u003cp\u003eA: The meter body measures 48 × 29 × 26 mm, and the panel cutout (mounting hole) required is 46 × 27 mm, making it easy to install into a dashboard, enclosure, or custom panel.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Is this digital battery voltage meter compatible with lithium battery packs?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes!
