The traditional Li-ion battery with protective plate is the nickel plate connection method for the negative protection circuit, while the Weltool PB18-30P uses the built-in protection circuit in the battery positive technology, the steel shell is riveted and integrated with the battery core, effectively avoiding short circuit caused by collision or wear and so on,and will not increase the battery diameter.
Selected 18650 Li-ion battery cells, low internal resistance, high capacity, large discharge current; battery has triple overheat protection: pressure safety valve protection, diaphragm micro hole protection, PTC cathode blocking protection and positive protection circuit with four protections : Overheat protection, overcharge protection, over discharge protection and short circuit protection. The battery positive cap is raised. It is used in the flashlight to contact the positive spring or the PCB contact surface is tighter. Single or multi-cell batteries can be used at the same time.
