Heltec Energy 2S-24S Lithium Battery Equalizer, 0.4A/0.7A Active Balancer, 2-4.5V Battery Maintenance Repair Tool for NCM LFP LTO Battery Pack

Summary

This equalizer directly displays the sum and voltage difference of each string

Solves the problem of battery pack unbalance with one button

The equalizer starts the equalization with one button, and automatically stops after the equalization is completed, and warns

Our equalizer will not charge the batteries during the equalization process. So don't worry about the danger of overcharging the balance

Note:

Before balancing, please check whether the lowest voltage is lower than the battery's over-discharge voltage. If it is lower than the battery's over-discharge voltage, please charge the balance first, and the battery is fully charged and then balance, the effect will be better.

Feture

Support 2~24 series lithium battery pack, support ternary lithium, lithium iron phosphate, too cobalt lithium, support 1.5V~4.5V battery, the voltage is out of range, it will sound a warning and display

Reverse connection warning and reminder: after connection reverse, overvoltage (greater than 4.5V), low voltage (less than 1.5V) protection functions are balanced, it will automatically stop, and a warning sound will sound to indicate that the balance is complete.

Display the voltage of each string, total voltage, highest string voltage, lowest string voltage, maximum voltage difference of battery pack, average voltage, balanced voltage, number of battery strings

Battery maintenance steps:

There is a bad battery cell:

1)replace the battery cell

2)fully charged

3)balancing

4)fully charged

5)battery maintenance completed

●Discharge method:

Advantage:

1. Don't charge the batteries, don't worry about overcharging problems

2. The speed of the whole equalization process is the same, and the equalization speed is fast

Disadvantages:

Since the equalization method is to discharge the high-voltage string energy until it is equal to the lowest voltage string, the excess energy is wasted.
