Plate extends its service life, effectively reduces risk, battery protection module is indispensable to ensure lithium battery normal use.
Traditional way is that battery protection module is arranged at lithium battery end, needs that two pieces of pcb boards are arranged, pastes IC twice, and subsequent
Welding will also carry out twice, not only increasing cost, but also the volume for increasing lithium battery has to increase the volume of entire product
Damage the beauty of hand string and the comfort level of wearing.
Therefore, the prior art is defective, needs to improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of miniaturized intelligent hand serializer circuit system,
