Enerkey Active Balancer BMS 5A for 3s 4s 5s 6s 7s 8s 10s 12s 14s 16s 17s 21s Lithium/Lifepo4/LTO Battery Equalizer
Product performance description
1.EnerKey 5A Active Balancer is suitable for NCM Ternary polymer
lithium battery (Li-ion), lithium iron phosphate battery
(LiFePO4),lithium titanate battery (LTO).
2.Working principle: Flycap-capacitor transfer charge transporter,
Balancer board is connected to the battery to start the balance
work, using the original brand new ultra-low internal resistance
MOS, 2OZ copper thickness PCB. Balance current 0-5.5A,
the more balanced the battery current is Small, reserved for the
dormant switch wiring position, the dormant power-off mode working
current is less than 0.1mA, and the balance voltage accuracy is
within 5mv!
3.The quiescent current is about 12mA, and the battery capacity is
recommended to be used between 30-300AH/Per Balancer.With
under-voltage sleep protection, only detecting the B1 battery
voltage,
the equalizer will automatically stop entering the sleep state when the B1 voltage NCM/LFP<2.7V or LTO<1.8V, and the standby power consumption is less than 0.1mA.

| Equilibrium method | The whole battery group simutaneously participates in the energy transter active equalizatior | ||||||||
| Equilibrium current | 0.1V Differential pressure 1A Balanced current, | ||||||||
| the differential pressure is proportional to the balanced current, | |||||||||
| the maximum allowable operating current is 5.5A | |||||||||
| Voltage equalization accuracy | 5mV (typical value) | ||||||||
| External power supply | No need for an external power supply, | ||||||||
| relying on the internal energy transfer of the battery to achieve sdjacent equalization. | |||||||||
| Quiescent current | 0.1mA(typical value) | ||||||||
| Operating Temperature | -20℃ ~ +60℃ | ||||||||
NOTE:
As shown in the figure above,there can be multiple common ends of energy exchangeso that the efficiency of equilibrium will be higher;It is also possible to use only one common end of theenergy exchange atthejunction of two modules.
The other free feet are suspended, and it is best todistribute the number of strings equally on each board.If you need the cascade diagram for more strings, Please contact our online service, Thanks.
