Different ways of balance:
1) distributed and centralized type, centralized type wiring is complex,distributed type wiring is simple.
2) parallel and serial type,parallel type has no voltage drop,doesn't affect normal use of the battery pack.
3) dynamic type and static type, dynamic type balance the batteries voltage all the time within the range of battery working voltage.
4) two-way type and One-way type, two-way type use two-way converter, two-way adjust charging and discharging of single cell
5) parallel type and progressive type, parallel type balanced, fast, efficient;
6) energy transfer type and energy consumption type, Energy transfer Type is to transfer energy to achieve the result of balancing single cells. little loss, less heat.
Enerkey equalizer module adopts distributed ,parallel,two-way,energy transferring type which is the ideal balance solution.Using the latest circuit technology and devices, such as synchronous rectification, soft switches, etc., to achieve high efficiency and high product reliability.

| LTO version: 1.89V | |||
| 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 | |||
| 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℃ | ||
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.
