The balance board is suitable for  the li-ion battery pack BMS WHICH without  balance function,so as to  equalizing charge lithium battery charge function, make the battery pack each series charge at the same time.
Note:The balancing board must need BMS to use together,and the BMS is without balancing function
Parameter:
Balance Voltage for each single cell: 4.2V
Balance current for each single cell :66mA
Size: L25mm*W22mm
Balancer is just a Auxiliary function, The balancing means when the battery charging,each series battery need with the same voltage.when ONE cell voltage get 4.2V ,the other cells not, the first cell voltage will discharge to wait the other cells rising to the same level.
Note:
battery internal resistance differences within 5 milliohm, voltage within 0.03 V voltage, capacity vary within 50 ma
Cut-off  Voltage is according to the BMS setting.
Note:the balancer starts balancing when the one cell get 4.2V, The Cut-off  Voltage is according to the BMS setting,but the bms cut-off voltage needs more than 4.25V which is much better.

Functional Description:
Undervoltage lockout and activation
IP5328P battery at the first access, regardless of how much the battery voltage, the chip is in a locked state, the least significant bit will flash charge lamp 4
Prompt times; when non-charging state, if the battery voltage is too low to trigger a low-power shutdown, IP5328P will enter a locked state.
In the locked state, in order to reduce static power consumption, IP5328P was no phone insertion detecting function can not be activated by a button. this
When the button action can not be activated boost output, but the power light will flash four times the lowest level prompt.
In the locked state, it is necessary to enter the state of charge in order to activate the chip functions.
Charging
IP5328P has a constant synchronous switch structure, the constant-voltage rechargeable lithium battery management systems support. It can automatically adapt different charging
Pressure specifications.
When the battery voltage is less than 3V, 250mA using trickle charge; when the battery voltage is greater than 3V, the input into the constant current charging, the battery maximum charging end
Electric current 5.0A; when the battery voltage is set close to the battery voltage, constant voltage charging; end of the charging when the battery current is less than about 300mA and electrical
When the battery voltage is close to the voltage of the constant voltage, the charging is stopped. After completion of charging, if the battery voltage is below 4.1V, the battery back on charge.
IP5328P switch using charging techniques, the switching frequency is 500kHz. Ordinary 5V input charge, the maximum input power 10W; fast charge input
When charging, the maximum input power of 18W. End of the battery maximum charging current up to 5.0A, the maximum charging efficiency of 94% , the charging time can be shortened to 3/4.
IP5328P automatically the charge current, the adapter to accommodate different load capacity.
IP5328P does not support the same charge and discharge the same, the state of charge and discharge the output port is closed, to prevent damage to the high voltage charging device is input.
Boost
IP5328P a support integrated high voltage output of the synchronous switching systems, to support a wide voltage range of 5V ~ 12V output, negative
Carrying capacities of 5V-3.1A, 7V-2.4A, 9V-2.0A, 12V-1.5A. Switching frequency 375KHz. Built-in soft start
Function to prevent inrush current at startup failure caused by excessive, the integrated output overcurrent, short circuit, overvoltage, overtemperature protection,
To ensure stable and reliable operation of the system.
Boost system can automatically adjust the output current with temperature, to ensure that the IC temperature below the set temperature.
