Active Balancer 2-24S Super-Capacitor 4A BT App Li-ion / LiFePO4 / LTO
The basic principle of the active equalization technology is to use the ultra-pole capacitor as a temporary energy storage medium, charge the battery with the highest voltage to the ultra-pole capacitor, and then release the energy from the ultra-pole capacitor to the battery with the lowest voltage. The cross-flow DC-DC technology ensures that the current is constant regardless of whether the battery is charged or discharged. This product can achieve min. 1mV precision while working. It takes only two energy transfer processes to complete the equalization of the battery voltage, and the equalization efficiency is not affected by the distance between the batteries, which greatly improves the equalization efficiency.

Smart BMS 8-20S 40A 100A 200A Bluetooth For Lithium Battery
Smart BMS supports BT communication function with mobile APP (Android/IOS). You can check battery status in real time through APP, set protection board working parameters, and control charge or discharge. It can accurately calculate remaining battery power and integrate based on current time.
When in storage mode, the BMS won’t consume the current of your battery pack. To prevent the BMS from wasting power for a long time and damaging the battery pack, it has an automatic shutdown voltage. When the cell falls below the voltage, the BMS will stop working and automatically shut down.

Active Balancer 3-4S 3A Battery Equalizer with TFT-LCD Display
As the number of battery cycles increases, the rate of battery capacity decay is inconsistent, leading to a serious imbalance in battery voltage. The “battery barrel effect” will influence the service life of your battery. That’s why you need a active balancer for your battery packs.
Different from inductive balancer, capacitive balancer can achieve the whole group balance. It doesn’t need voltage difference between adjacent batteries to start balancing. After the device is activated, each battery voltage will reduce the capacity decay caused by the battery barrel effect and prolong the duration of the problem.

Active Balancer 4S 1.2A Inductive Balance 2-17S LiFePO4 Li-ion Battery
There is adjacent voltage difference of batteries when charging and discharging, which triggers the equalization of this inductive balancer. When the adjacent battery voltage difference reaches 0.1V or more, the internal trigger equalization work is performed. It will keep working until the adjacent battery voltage difference stops within 0.03V.
The battery pack voltage error will also be pulled back to the desired value. It’s effective to reduce battery maintenance costs. It can significantly balance battery voltage, and improve the overall efficiency of the battery pack.

Battery Equalizer 2-24S 15A Intelligent Active Balancer For Lithium Battery
This is a tailor-made equalization management system for high-capacity series-connected battery packs. It can be used in the battery pack of small sightseeing cars, mobility scooters, shared cars, high-power energy storage, base station backup power, solar power stations, etc., and can also be used for battery equalization repair and restoration.
This equalizer is suitable for 2~24 series NCM/ LFP/ LTO battery packs with voltage acquisition and equalization functions. The equalizer works with a continuous 15A equalization current to achieve energy transfer, and the equalization current does not depend on the voltage difference of the series-connected cells in the battery pack. The voltage acquisition range is 1.5V~4.5V, and the precision is 1mV.

Battery Repairer 2-32S 15A 20A 25A Lithium Battery Automatic Equalizer HTB-J32S25A
This model can do Manual Equalization, Automatic Eualization and Charging Equalization. It direct displays the voltage of each string, total voltage, highest string voltage, lowest string voltage, balancing current, temperature of MOS tube etc,.
The equalizer starts the compensation with a button, stops automatically after the compensation is complete, and then warns. The speed of the whole balancing process is the same, and the balancing speed is fast. With the single overvoltage protection and single overvoltage recovery, this model can do the balancing work under safety insurance.
While balancing, it also allows charging simultaneously, which means more efficiency and better practicality.
