Product Description

 

4S 5A Battery Energy active equalization Balancer.

 

DESCRIPTION:
This is a 4S LiFePo4lithium-ion 5A equalizer used for 12V battery pack.
This device acts as a balancer/equalizer to balance the capacity of cells inside 12V battery pack.
This is not a Bluetooth balancer/equalizer.
This can be used in lithium batteries of any type including 18650/21700/32650/38120/66160 and any type of prismatic cells etc.
This can be used in lithium battery applications including solar, RV, Electric bikes, Skate board, camping, Boat, Power tools, Lawn moving and household energy storage systems.
This can be used for 3S and 4S battery pack configurations.

Balanced Cascading
Support balanced cascading for battery packs, for example , it can cascade for 11S , 24S ,36S , 48S....and so on
Single cell voltage collection range
NCM/LFP version : 2.7V-4.2V
LTO version : 1.8-4.2V
Undervoltage protects sleep voltage
NCM/LFP version<2.7V
LTO version<1.8V
Equilibrium method
Patented (Patent No.: ZL 2019 1 1259513.3) balanced architecture Fit capacitor method, the entire battery pack is balanced at the same time.
Connect to the battery pack for automatic balancing (default). You can add a switch to manually turn on or off balancing.
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 operating current 7mA, the total string draws power
Sleep standby current
0.1mA(typical value)
Operating Temperature
-20℃ ~ +60℃

 

 

Packing List

 Wire connect

A single EK-C4S5A supports the use of 3s and 4s string battery packs. The wiring method is as follows:


EK-C4S5A supports cascading battery packs. Fox exmple, 2pcs of 4s cascade to 7s, see below drawing:

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.
