Overview:
The main IC uses “Seiko” imported components. With overcharge, over discharge, over current, short circuit and other protection functions, for a variety of shapes of various shapes 3.7V lithium battery. High-quality MOSFETs such as Seiko protection IC, VISHAY, AOS, IR, etc., FR-4 low temperature coefficient sheet, well designed and tested. It is small in size and suitable for many applications requiring high integration and low cost. It can meet various performance requirements and ensure the absolute safety and reliability of the battery pack.
