Description
There are two main methods for battery cell charge balancing: passive and active balancing.
This voltage balancer does not waste energy in resistors; it transfers the coulombs from a strong cell to a weak cell.
This is ideal for electric vehicles to prolong its battery cycle life by preventing cell over/under charging; promoting cost-effective sustainable transportation.
Batteries are expensive, this project will help any diy electric vehicle battery to last longer. Battery capacity limited | Unlimited | Battery count limited | 2S~unlimitedAt least balance 2 cells |
| 1.8V~5V (2V lead acid battery and lithium battery)4V~9V (6V lead acid battery) 9V~15V (12V lead acid battery and lithium battery) | Battery type limited | LiFePo4, LiMnO4 etc AGM, Gel, Flooded battery and so on. |
Power consumption | <50mW per 1s | Balance method | Energy transfer/ Dynamic |
Voltage difference VS Balance current | | Voltage difference after using | < 10mV< 30mV(12V lead acid) |
Working efficiency | > 94% | Working temperature | |
BMS limited | Can work with BMS or Wordking independently | Storage temperature | -40ºC ~ +100ºC |
Advantages
1. Keep the voltage difference of each cell within 10mv.
2. Extend the battery span life 2-3times. Without capacity & voltage & battery type limitation .

Customers feedback:
Customers good review & feed backLatest American clients after using our balancer said: balancers are great and works very well, they feel very happy.
A customer from New Zealand said:
When i turner the balancer on the cells were more than 100mv, after a few hours the cells were only a few mv from each other.
He was so pleased with the results and have discussed with a few EV club members, he will promote our balancers to a wider audience in New Zealand.
Certification
Our Service1. OEM Manufacturing welcome: Product, Package. At least 100 pcs.
2. We will reply you for the inquiry within 24 hours.
3. After sending, we will track the products for you once every two days, until you get the products. When you got the
goods, test them, and give me a feedback.If you have any questions about the problem, contact with us, we will offer
the solution for you.FAQQ1. What's the benefits of the balancer?
A: 1, Keep your batteries voltage difference within 10mV!
2, Keep your batteries safe all the time. no overcharging or over discharging.
3, Prolong your battery lifespan 2~3times.
4, Low price. you pay a small amount of money to protect your battery. Compare to the cost of replacing your expensive lithium battery, the balancer is very cheap.
Q2. How is the balancer working? How can they protect batteries?
A: Below 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.
the balancers are connected in parallel to the batteries. they won't affect the charging or discharging of batteries.Q3. What is similarity and difference between single cell (1S) balancer and balance module?
A: 1.Size is different. Overal speaking,balance module is smaller in size and lighter in weight.
2. Balancer module use less wires for installation than 1S balancer.
3, When your pack is over 90V,we recommend balance module because of the reasons above.below 90V,both of them are fine.
4,Similarity: Function is the same. Performance is the same. Price is the same. 4S module price=4 *1S balancer price
5, We have 3S 5S 6S 8S 10S 12S for options.Please choose the proper model in terms of the layout of your battery pack.
Q4. I have a BMS already. Do i still use the balancers?
A: Yes sure.you can use your BMS and the balancers together. They won't affect each other.this is perfect.The balancers can make up the shortcoming of BMS and improve the consistency of your batteries.
Q5. Are you manufacture of the balancer?
A: Yes,we are the inventor and manufacturer of the balancer since 2010.
Q6. What is delivery time of the balancer?
A: For sample order, in stock, 1 working day can be shipped out. For volume order, 5-10days
