Lead Acid Battery Equalizer 10A Active Balancer 24V 48V LCD
The battery equalizer is used to maintain the charge and discharge balance between the batteries in series or parallel. During the working process of batteries, due to the difference in chemical composition and temperature of the battery cells, the charge and discharge of every two batteries will be different. Even when the cells are idle, there will be an imbalance between cells in series due to varying degrees of self-discharge. Due to the difference during the charging process, one battery will be overcharged or over-discharged while the other battery is not fully charged or discharged. As the charging and discharging process is repeated, this difference will gradually increase, eventually causing the battery to fail prematurely.

Smart BMS 8-24S 72V For Lithium Battery 100A 150A 200A JK BMS
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.

Transformer 5A 8A Battery Equalizer LiFePO4 4-24S Active Balancer
This active equalizer is a transformer push-pull rectification feedback type. The equalizing current is not a fixed size, the range is 0-10A. The size of the voltage difference determines the size of the equalizing current. There is no requirement for voltage difference and no external power supply to start, and the balance will start after the line is connected. During the equalization process, all cells are balanced synchronously, regardless of whether the cells with differential voltage are adjacent or not. Compared with common 1A equalization board, the speed of this transformer balancer is increased by 8 times.

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.

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.

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.
