1.Technical parameters

Working voltage: 1.8V-4.5V.Suitable for ternary lithium, lithium iron phosphate,Lithium polymer, lithium titanate.

2.Why need?
(1).As the battery battery cycle times increase, the battery capacity decay speed is inconsistent, causing the battery voltage to be seriously out of balance.
(2).The battery barrel effect will cause the battery to charge. The BMS system detects that the battery has entered the overcharge protection in advance. In fact, only one of the batteries is full, or let The BMS system detects that the battery enters the over-discharge protection state, which is actually caused by over-discharge of one of the lower-voltage batteries. After the device acts, each battery voltage reduces the capacity attenuation caused by the battery barrel effect and prolongs the problem. The battery pack has a service life.

3.Working principle
(1).The capacitor fit transfers the charge mover, the equalization board is connected to the battery, and the equalization is started,No voltage difference is required.
(2).The original new ultra-low internal resistance MOS, 2OZ copper thickness PCB.
(3).Equilibrium current 0-5.5A, the more balanced the battery, the smaller the current, with manual sleep switch, sleep current mode is less than 0.1mA, the balance voltage accuracy is within 5mv!
(4).The quiescent current is about 12 mA. It is recommended that the battery capacity is 30-300AH.
(5).With under-voltage sleep protection, the voltage will stop automatically when the voltage is lower than 3.0V, and the standby power consumption is less than 0.1mA.
(6).For all means suitable for ternary lithium, lithium iron phosphate, Lithium polymer,lithium titanate.

3.Balanced Cascading
(1).Support balanced cascading for battery packs, for example , it can cascade for 11S , 24S ,36S , 48S….and so on
(2).li-ion /lifepo4/lipo/LTO version can switch between Lifepo4/Li-ion and LTO , just changing welding point.
(3).With manual sleep switch interface
