Customer Reviews
i have a nice memory of our meeting in Shenzhn with Deligreen Mandy and a beautiful impression of your growing company.We both are straightforward and honest people and this is the most important value,so i am sure we can

—— Angelo from Italy

I am sure we can happily work together we should easily find a way to do.Money are important but aren't the most important part.

—— Angelo from Italy

Deligreen is the partner that i have replied one for years. Some other suppliers change sales quickly but Deligreen not.

—— Bonnett from USA

i have used the batteries for 9 years from Deligreen. Amazing!

—— Phil, LA

COVID19 made something more difficult. we need the balancers urgently.Thanks for the Deligreen team's effort. We receive the balancers on time and no delay for our project. Thank godness

  • Deligreen Battery Balancer module is a mutual way energy transfer system .With advantage of high efficiency and low power consumption, it will discharge the cells once it detected any cell whose voltage is above the average value.Thus it can let all the batteries voltage keep balanced and share power among all the cells.
  • Deligreen battery equalizer use the balance way of dispersion, parallel,dynamic,bindirection ,Through this way,It maintains the batteries in the long term running so that the lifespan of the battery pack is prolonged.Deligreen Battery Balancers are widely used for lithium-ion batteries,lead acid batteries,NiMH batteries and Super capacitors.the balancer module prevents the lead acid batteries from vulcanization and also has capability to repair vulcanization.

Why Should We Choose Deligreen Battery Balancer?


Three factors that cause the batteries decay or defective :

  1. Over discharge
  2. over charge
  3. under charge

12V 1S Lead Acid Flooded AGM LiFePO4 Battery Balancer 0

one cell lifespan can be over 2000times


12V 1S Lead Acid Flooded AGM LiFePO4 Battery Balancer 1

When they are assembled in a pack, how many cycles can it be?

1000 times or 500times or lower? How to solve the problem?


Before using Deligreen Balancer

12V 1S Lead Acid Flooded AGM LiFePO4 Battery Balancer 2

Battery voltages are different with each other.

So some cells can’t be charged fully.

During discharging, the capacity can’t be fully used .


After using Deligreen Balancer

12V 1S Lead Acid Flooded AGM LiFePO4 Battery Balancer 3

Each cell voltage equal to each other.

All the cells can be fully charged.

They can share power with each other.

The capacity can be fully used.


Deligreen Battery Balancers can Keep battery volt difference within 10mV(30mV for 12V lead acid battery)

Help prolong battery’s lifespan 3~4times!


More Details about the Features

1 Online working balance during charge,discharge, and storage

2 Dynamic equalizing Prevent batteries out of balancing all the time

3 Energy transfer Transfer energy from higher voltage cells to the lower ones

4 Maintenance and recovery Keep normal batteries at good condition, recover the backward ones

5 Sharing capacity The power will flow from one cell to another and share them among all the cells


6 Simple installation Connect the balancers together and then connect to battery+ and battery-

7 Independent No affect to battery pack wiring, no impact to charging or discharging


How is the balancer working?

This diagram tell you how the balance work.

Each battery is compared to a cup. Each balancer is like a pump. with the pumps, all the cups will have the same level of water.

Comparison between BMS/PCB and Deligreen Balancer


Typical PCB/BMS in the market in the world Deligreen Balancer
Balance method

Active 20%

Passive 80%

Active Energy transfer& dynamic
Balance current

50mA~6A Adjust the current automatically

The bigger the volt difference,the higher balance current.




Software and hardware update quickly


High reliability

The first batch of balancers were used on e-truck in 2009.

They are working fine till now.


PCB is simple

BMS is complicated in some degree,technical people can do it.

Very simple

Everyone can install.


How many batteries can balance each time ?

Passive 2 or 3 cells

Active 1 or 2 cells

all the cells balance together


Balance Efficiency

Active 80%

Passive <80%,

Passive balancing is to consume the power of the higher cells and let it closer to the lower ones.This cause lose of energy.



Battery capacity after 3month~2year



e.g:If one cell is 3.7V,others are 3.6V3.5V,3,4V,BMS/PCB will cut off charging.the other battery can’t be fully the capacity decay day by day.





Volt difference after balancing

Hard to say.

Depends on battery pack itself

The bigger difference ,the longer time it runs


50mV for 12V lead acid cell

Over charge protection

No (standard)

Yes(customized MOQ>1000pcs)

Over discharge protection

No (standard)

Yes(customized MOQ>1000pcs)

Short circuit protection



Over current protection




Battery pack with BMS without balancer


Battery pack with BMS and balancer

Within 1~3 years, need to replace new battery

Battery volt difference becomes bigger as time goes by,BMS can’t help since the balance performance is unsatisfactory.

Free maintenance

No need to replace any battery only if you use them properly. the balancers keep the batteries volt difference within 20mV. It is difficult to be overcharged or over discharged.this situation can last 8~10years
