Frequently Asked Questions
Q: What types of batteries is this voltage indicator compatible with?
A: This battery capacity meter works with a wide range of battery chemistries, including Lead Acid, Ternary Lithium (Li-ion), and Lithium Iron Phosphate (LiFePO4) batteries across a DC 7–100V range. Use the [P], [L], [F], or custom [C] mode to match your specific battery type.
Q: Will my custom voltage settings be saved if the meter loses power?
A: Yes! The meter features power-off memory, meaning your custom voltage parameters are retained even after disconnecting from the battery. You won't need to reconfigure your settings each time.
Q: What applications is this battery meter best suited for?
A: This meter is ideal for monitoring batteries in electric vehicles (e-bikes, scooters), outdoor power stations, solar energy storage systems, vacuum cleaners, and DIY electrical projects requiring accurate DC voltage and charge level readings between 7V and 100V.
Q: How accurate is the voltage reading?
A: The voltage acquisition accuracy is ±1.0%, providing reliable and precise readings for effective battery monitoring and management.
