common problem

1. Can my battery use your protection board?

Answer: There are two questions to consider whether you can use this protection board: First, how many strings your battery is, you have to buy the protection board corresponding to the number of strings. Second, what material is your battery? We have two types of protection boards for lithium iron phosphate and polymer lithium batteries. If your battery is a single-cell lithium iron phosphate with a nominal 3.2V, you need to choose lithium iron phosphate 3.2 in the category. For V, if it is a polymer (ternary, cobalt acid, lithium manganate battery) single cell battery with a nominal 3.6V (or 3.7V), please choose the polymer 3.7V classification.

2. How can I judge what material my battery is made of?

Answer: You can take a look at the nominal voltage of your battery. Lithium iron phosphate batteries are generally rated 3.2V, and other batteries are generally rated 3.6V or 3.7V. You can also directly ask the seller of the battery what material is it Many buyers say that my battery is 18650 or 26650 soft pack, etc. This is the shape, not the material! We cannot determine your battery protection parameters based on this.

3. How many A protection boards should I choose?

Answer: How many A protection boards to choose depends on the power of your product or the current limit of the controller. For example, 10A for those below 100W, 20A for those below 200W, 25A for those below 300W, and contact us for protection boards above 500W. The current cannot be less than the controller current limit.

4. My battery is 20AH, can I use this protection board?
