FAQ
Q1. 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
