12V Lead Acid Battery Balance With Led Indicator 1S Battery
Equalizer BMS Battery GELL Flooded AGM
Overview
- 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 :
- Over discharge
- over charge
- under charge
one cell lifespan can be over 2000times
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
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
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 |
| 15mA~1A | 50mA~6A Adjust the current automatically The bigger the volt difference,the higher balance current. |
Lifespan |
2~4years Software and hardware update quickly | 8~10(10~15)years High reliability The first batch of balancers were used on e-truck in 2009. They are working fine till now. |
| Installation |
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. | >94% |
Battery capacity after 3month~2year
|
70% 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 used.so the capacity
decay day by day.
| 95% |
Volt difference after balancing |
Hard to say. Depends on battery pack itself The bigger difference ,the longer time it runs | 10mV~20mV 50mV for 12V lead acid cell |
| Over charge protection |
| Yes | No (standard) Yes(customized MOQ>1000pcs) |
| Over discharge protection |
| Yes | No (standard) Yes(customized MOQ>1000pcs) |
| Short circuit protection |
| Yes | Yes
|
| Over current protection |
Yes
| Yes |
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 |
