Product Introduction of Lithium Battery Protection Board
The main IC of this lithium battery protection board adopts original “Seiko” imported components. It features protection functions such as overcharge, over-discharge, overcurrent and short circuit protection, and is suitable for 3.7V lithium battery cells of various capacities and shapes. It uses Japanese Seiko protection ICs, high-quality MOSFETs from VISHAY, AOS, IR, etc., and FR-4 low temperature coefficient boards. With sophisticated design and comprehensive testing, it has a compact size, making it suitable for many occasions requiring high integration and low cost. It can meet various performance requirements and ensure absolute safety and reliability of the battery pack.
