"Multifunctional integration: Intelligent, automatically identifies battery wiring harness and various faults, and the host or computer can flexibly set parameters." " Information at a glance: 3.5-inch high-definition LCD display screen, with clear information such as string number, total voltage, single string voltage, voltage difference, and whether each string of batteries is connected correctly, supporting Chinese and English switching." "Energy transfer type active balancing: With a balanced current of up to 10A, quickly completing cell voltage difference repair; It can also automatically stop equalization, after the pressure difference is equalized to the set value, equalization automatically stops without being on duty." The equipment is safe and reliable: high temperature protection, low temperature protection, high voltage protection, low voltage protection, reverse connection protection, and short circuit protection. "Long term self power supply: Equipped with 18650 lithium battery for independent power supply, capable of working for 4-6 hours without external power supply. " The instrument can quickly and efficiently detect, repair, and maintain multiple series of battery packs. It is practical and portable, especially suitable for online and offline detection, analysis, and maintenance of multiple batteries by battery manufacturers, battery distributors, battery repair shops, and DIY users.Improve battery assembly efficiency and repair batteries safely and efficiently.
