1pcs QNBBM 1S 3.2V3.7V Battery Equalizer  Single Cell Lithium LiFePO4 Li-ion 18650DIY Balancer BMS LIFEPO4 /Polymer LTO Pack

Attention:

This link is for NON-led balancer only, if you need balancer with led indicator, please order from the link below:

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 balancer 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.

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 Battery Balancer/Equalizer

Battery voltages are different with each other. So some cells can’t be charged fully.

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

See the photo below

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.

See the photo below:

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

Help prolong battery’s lifespan 3~4times!

First,if you order 1S balancers,we have 20cm wires on the balancers with M8 terminals as default .

If you need other size of terminals and different length of wires,please tell us.

If you order balance modules,no terminals or wires.

Second,The balance power consumption is less than 50mW.

If you don’t use the battery for over 2months,please either disconnect the balancers,

or recharge the battery once a month or once two months.

Recharging the batteries occasionally is better for your batteries as well.

Third, we have wiring diagram on the balance modules. Don’t make any mistakes.

If you are unsure of installation, please contact our sales person.we will be glad to help you.

Here are several ways of making a judgment where you install them correctly or not.

1,Measure voltage of the batteries with a multi-meter after you finish installation. See if all the batteries voltage is normal or not.

2,Touch the batteries.if any battery get hot quickly,disconnect the balancers soon.this means you install them in the wrong way.

If you find the mistake in a few minutes,the battery won’t be broken.

3,Listen. If the balancers are connected correctly,they will produce a high-frequency voice.the voice is small.

You need to get close to the balancers.

The more balanced the batteries are,the smaller the balance current it will have,

and the smaller voice there will be.and vice versa. if you connect them in wrong way,you can’t hear any voice.

Project name: Communication base in Shenzhen

Time: March 2013~ 2017

1st pack without balancer       2nd pack with balancer

We measure the two packs 4 times.

1st pack without balancer volt difference is :   87mV,  83mV,  83mV, 91mV

2nd pack without balancer voltage diffence is:101mV, 105mV, 9mV,  8mV

Test result: After 4years, the 2nd pack are in good condition. The 1st pack capacity only left 50%

Typical case 2
