Frequently Asked Questions
Q1: I have a BMS already, can I use the balancer?
Yes, sure. If you use the BMS and balancer together, that will be perfect. Most BMS are intelligent and can display battery information, but you might feel the balance performance is not satisfactory. Now adding the balancer will help you solve the problem.
Q2: What is power consumption of the balancer?
The power consumption is very low, only 50mW.
Q3: If I don't use the batteries for a long time, should I disconnect the balancers?
Normally if you don't use the batteries for 2~3 months, you need to recharge the batteries. This is necessary for battery maintenance. Since the balancer power consumption is low, it won't consume much power from the battery. Whether you need to disconnect them or not depends on what capacity is your battery pack. For a 10AH and 100AH pack, the result is different. You can contact us and tell us your situation in details. We will be glad to give you professional suggestion.
Q4: My battery is NiCD or other special battery. The nominal volt is only 1.2V. Can I also use your balancer?
Yes that is possible. We have solutions. For example, we can use 1 piece of balancers for two of your cells. We have many customers who have such special batteries. The balancers prove to be working great as well.
Q5: What is application of your balancer?
Lithium battery, lead acid battery, super capacitor
Q6: What is delivery time of your balancer?
1~2 business days if in stock. 1~3 weeks for volume order
