12cells~ 24cells bluetoo BT Active bms balancer for catl lithium battery 21700 battery

There are more and more customers need our active balancer to extend the lithium-ion battery life. On the market, you maybe buy some low cost cells which is low quality and can not have similar cell characters to assemble together in one pack and caused the battery pack can not work well and long cycle life for some of the cells consume power quickly than other cells. The active balancer here can move the energy from cell to another cell to let them match better and the battery pack can have longer life.

This 12 cells~ 24cells 1A BT APP Battery Active Balancer Fit For below batteries Li-ion Lipo LiFepo4 LTO Lead Acid Batteries:

1.  3.6V Li-ion battery packs by using 18650 cells made by Panasonic, Sanyo, LG, Samsung, SONY

2. 2.4V LTO battery packs by using lto cell brands Yinlong, Tiankang, Toshiba, Microvast

3. 3.7V LiPolymer battery packs by using lipo cell brands LG, Samsung, Varta, Panasonic, Kokam

4. 2.0V lead acid battery brands like Exide, Yuesa, CSB, Crown,Vision, Varta,etc..

The battery active equalizer is a balanced management system tailored for large-capacity tandem lithium battery packs. The equalizer uses supercapacitor as a medium to achieve active energy transfer equalization.

The equalizer is suitable for 12S-24S battery packs with voltage acquisition and equalization. When the equalizer is working, the energy transfer is performed with an equalizing current of 1 A. The equalizing current does not depend on the voltage difference of the series connected cells in the battery pack. The voltage acquisition range is 1V-5V and the accuracy is +/-5mV. It can be applied to all kinds of lithium batteries on the market such as lithium iron phosphate, lithium,Lipo,Li-ion and LTO.

The equalizer has BT communication function and is equipped with mobile APP software. You can check the cell voltage, view the balance status, and modify the setup parameters through the BT connection equalizer. It can be used in small sightseeing vehicles, scooters, shared cars, high-power energy storage, base station backup power, solar power stations and other products in the battery pack.

Features:
1. Support 12-24S battery pack
2. Real-time, active, energy transfer equalization, after the balance is reached, the pressure difference between the cells is less than or equal to 3mV
3. Support all battery types such as lithium iron phosphate, lithium,Lipo,Li-ion and LTO, super capacitor
4. The equalization current is set independently in the range of 0.1-1A, independent of the cell voltage difference
5. Support balanced cascading to apply to battery packs above 24S, theoretically there is no limit
6. BT communication function, equipped with APP, check battery status in real time
7. Balanced resistance detection, abnormal contact failure is found in advance
8. No external power supply, direct battery pack power supply, power supply range: 40V-100V
9. Low voltage shutdown function to prevent battery damage
