New Product Online: Heltec 4S 6S 8S Active Balancer Lithium Battery Balancer with Display |

Introduction:

As the battery battery cycle times increase, the battery capacity decay speed is inconsistent, causing the battery voltage to be seriously out of balance. The battery barrel effect will cause the battery to charge.
The BMS system detects that the battery has entered the overcharge protection in advance. In fact, only one of the batteries is full, or let The BMS system detects that the battery enters the over-discharge protection state, which is actually caused by over-discharge of one of the lower-voltage batteries.
At this time you need to use active balancer, after the device acts, each battery voltage reduces the capacity attenuation caused by the battery barrel effect and prolongs the problem. The battery pack has a service life.Are you looking for a compact and portable Balancer? Our new product, the 5A capacitor active balancer, can meet your various needs.

Heltec battery active balancer has a full-disk balancing function, which can automatically balance the battery pack without priority, and also has an automatic low-voltage sleep function. When the voltage difference reaches 0.1V, the balancing current is about 0.5A, the maximum balancing current can reach 5A, and the minimum voltage difference can be balanced to about 0.01V. This product is suitable for ternary lithium and lithium iron phosphate batteries and has over-discharge protection function. The battery voltage display supports real-time monitoring of the voltage of the entire battery pack and the voltage of the single cell, with an accuracy of about 5mV. The circuit board adopts a three-proof coating, which has excellent insulation, moisture-proof, leak-proof, shock-proof, dust-proof, corrosion-proof, anti-aging, anti-corona and other characteristics, effectively protecting the circuit and improving the safety and reliability of the product.

External power	No external power supply is required, and the whole battery group is balanced by relying on the internal energy transfer of the battery.

Suitable for ternary lithium, lithium iron phosphate, lithium titanate.
Working principle, the capacitor fit transfers the charge mover. Connected the balancer to the battery, and the balancing will started. The original new ultra-low internal resistance MOS, 2OZ copper thickness PCB.
Max Balancing current 5.5A, the more balanced the battery, the smaller the current, with manual sleep switch, sleep current mode is less than 0.1mA, the balance voltage accuracy is within 5mv.
With under-voltage sleep protection, the voltage will stop automatically when the voltage is lower than 2.7V, and the standby power consumption is less than 0.1mA.
The circuit board is sprayed with three-proof paint, which has excellent insulation, moisture-proof, leakage-proof, shock-proof, dust-proof, corrosion-proof, anti-aging, corona-resistant and other properties, which can effectively protect the circuit and improve the safety and reliability of the product.
