1. With acrylic shell baffle2. Support 1-24 series lithium battery packs (batteries with voltage between 2V-4.5V)3. Display the voltage, voltage, maximum string voltage, minimum string voltage, maximum differential voltage, average voltage, equalizing voltage and number of strings of each string4. The accuracy of each string of voltage is about 0.0035. There are reverse connection, high voltage (more than 4.5V), low voltage (less than 2V) warning sounds and prompts6. Type-c and DC power supply modes (5V power supply)7. Supports mixed insertion (not starting from B1)8. Can switch between and EnglishPort: 24 series lithium battery expansion board portPower supply port: Type-c and DC5V interfaceApplicable product: support 1-24 series lithium battery packof application: applicable to voltage detection of single battery pack/differential pressure repair of lithium battery packProduct size: 14 x 9.5 x 3.6cmOperation steps:1. Turn off the power switch after the equipment is powered on2. The battery pack is wired according to the label on the device or adapter board3. Check whether the display data on the display screen is normal. If it is abnormal, check the wiring or battery packNote: The mating adapter plate is equipped with a 2.0/2.54 pitch pin position, and cannot be connected to two interfaces at the same time.Colour:BlueMaterial:PCB + metalPackage Contents:1 x 1S-24S lithium battery pack voltage test screen1 x DC power cord1 x Expansion boardOnly the above package content, other are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
