- The product uses the standard lithium battery 3-series mode voltage (L03). Ternary lithium battery type L measurement: from the L03-series to the L20-series. Lead-acid battery type P measurement: DC12V, 24V, 36V, 48V, 60V, 72V, 84V. - Compatible with a wide range of batteries, including ternary batteries, lithium iron phosphate (LiFePO4) batteries, and lead-acid batteries. - Can be used with a variety of batteries, including ternary batteries, lithium iron phosphate (LiFePO4) batteries, and lead-acid batteries. - On the main screen, briefly press the button to switch the display mode; double-press to switch the display. Turning the display off enables low-power operation, with low alert, off, and memory storage functions. Use scenarios: - In a home energy storage system using LiFePO4 packs, to monitor voltage ranges from 12V to 84V. - In a lead-acid backup power setup for critical infrastructure, to manage DC voltages across multiple battery banks. - In electric mobility or fleet applications using ternary Li-ion cells, to track series voltage across L03 to L20 configurations.
