CW1244 3-string lithium iron phosphate battery protection balancing board

Introduction to CW1244 3-string lithium iron phosphate battery protection balancing board
The CW1244 series product is a highly integrated 3~4-string lithium-ion battery or lithium polymer battery protection chip. CW1244 provides overcharge, over-discharge, charge-discharge over-current, disconnection, charge-discharge over-temperature protection and balancing functions for the battery pack.
The basic principle
is to achieve the balancing and protection of three strings of lithium iron phosphate through a CW1244 chip. At the same time, in the circuit design, windowing is used to increase the current. For specific functions, please refer to the chip manual PDF in the attachment.
This board is compatible with ordinary lithium batteries. Please pay attention to purchasing the specified model of chip when purchasing the chip to avoid buying the wrong one.
Regarding welding,
B+ B- is connected to the positive and negative terminals of the battery,
3V6 7V2 is connected to the middle two sections of the battery in series,
P+ P- is connected to the charging and output to achieve protection
