--High-precision voltage detection circuit, fine workmanship and durable.

--Multiple protections: over-discharge / over-current / over-charge / short circuit protections; high charge and discharge current.

--Small size and light weight.

--Low internal resistance, high power MOS. The MOS tube can control the charging and discharging of the battery, and the standby current consumption is low.

--Application for 3.7V lithium batteries of various capacities and shapes.

Feature:

Application: Used for 3.7V lithium batteries of various capacities and shapes, battery packs for massagers, backup power for LED lights, battery packs for solar street lights, backup power for monitors, etc.
