This is a 3 in 1 battery voltage meter -With a switched function button to choose the battery capacity, real-time voltage or turn off; New alarm function, when the battery capacity is lower than 20%, the screen display will flash to alarm only need to connect to the battery, powered by tested circuit, don't need an extra power source (Note: package only include 1 battery meter)

1. Wide Working Voltage Range This battery monitor can tolerate the widest working voltage range (DC12V-84V).Can be adjusted to 12V/24V/36V/48V/60V/72V/84V, according to the battery voltage. Reverse Polarity Protection: Simple connection with reverse protection, wont burn if connect reversely.
2. Suitable Battery Types The battery detector is suitable for lithium batteries and lead-acid batteries, such as Ternary lithium batteries, polymer batteries, lithium-ion batteries, storage batteries. Note: it cannot be used for Lithium Iron Phosphate batteries, 1-2 Li batteries in series and over 15 Li batteries in series.
3. Clear and Bright LCD Display the battery detector shows the results through the clear LCD display with PVC waterproof screen protector and bright GREEN back-light. Less 50% power to loss than the others. What's more, there's a turn off button for it.
