It is particularly suitable for scenarios with rigid requirements for "20A continuous current-carrying + wear resistance + cost sensitivity," such as lithium battery PACK output interfaces, power tool battery packs, two-wheeled electric vehicle charging ports, AGV automatic charging contacts, and portable energy storage power supplies, precisely pairing with the female connector SYCBCHM01P2R1F to form a complete 20A-class lithium battery power interconnection solution.
