As the number of new energy vehicles has continued to increase in recent years, the technology and usage of lithium batteries have also continued to improve.People have found that lithium batteries will gradually reduce driving mileage and service life during use, affecting people's driving experience and driving safety.

Through research, it is found that lithium batteries are usually composed of multiple single cells connected in parallel or in series.During the production and use process, the charge and discharge status, internal resistance, etc. of each single battery may be different, resulting in inconsistent battery cells, resulting in a decrease in battery capacity, which in turn affects the performance and service life of lithium batteries.

Pain points and difficulties faced in after-sales service
1. There is a lack of equipment for balancing a single cell on the market;
2. When repairing and maintaining the battery, the working time is very long.
The balancer can be used to detect the voltage difference between different cells in the battery pack. Through charging and discharging, it can replenish the cells with lower power in the battery pack and release the cells with excess power. In addition, the balancer can also detect the health status of the battery, identify broken batteries or aging batteries, and provide alarm prompts.

Heruis LB series lithium battery balancer is mainly used to solve the problem of voltage inconsistency between battery cells

Heruis LB lithium battery balancer introduction and connection instructions
1. Before turning on the power, you need to confirm whether the power supply meets the input voltage and power frequency requirements of the instrument (AC100~264V50/60Hz), turn on the power;

2. Connect the battery pack:
The group A terminal wires in the figure below are used as an example. The wiring method of the terminals and the battery pack adopts negative terminal sequencing by default. The black wire is connected to the negative pole of the battery pack. The first red wire next to the black wire is connected to the first battery, the second red wire is connected to the second battery, and so on, until the twelfth battery.There are four types of Hirays lithium battery balancers, 12-string, 24-string, 36-string and 48-string, which means that up to 48 battery packs can be connected in series at the same time for testing.
