Common Problem

1. Can I use your protective plate for my battery?

A: There are two questions to consider whether this protective board can be used: 1.How many strings of your battery are, you need to buy the protective plate corresponding to the number of strings. 2.What is your battery made of? We have protection plates with two parameters, lithium iron phosphate and polymer lithium battery. If your battery is lithium iron phosphate with a nominal value of 3.2V, you need to select lithium iron phosphate with a nominal value of 3.2V. If your battery is polymer (ternary, cobalt acid, lithium manganate battery) with a nominal value of 3.6V (or 3.7V), you need to select polymer 3.7V.

2. How can I tell which material my battery is made of?

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

3. How many A’s should I choose?

Answer: The number of A protection boards selected depends on the power of your product or the current limit of the controller. For example, 10A is selected for those below 100W, 20A for those below 200W, 25A for those below 300W, and contact customer service first for those above 500W. The current of the protection board cannot be less than the current limit of the controller.

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

A: The capacity of your battery is not directly related to the current of the board. A large capacity is not a large battery, but mainly depends on the continuous current. That is, the larger your power is, the greater the continuous current of the protective board you choose. It is not directly related to the capacity of your battery.

5. How should the charger voltage be set?

The lithium battery shall be charged with a special charger for lithium battery, and the lead-acid battery charger shall not be used. The lead-acid charging may cause high-voltage breakdown of the MOS tube of the protection plate, which may cause the protection plate to be over charged and unprotected.

Charger voltage setting: use the number of battery strings * 4.2V, which is the charging voltage of the non iron lithium battery. The charging voltage of the iron lithium battery is the number of battery strings * 3.60V, which is the charging voltage of the iron lithium battery. The charging current standard is 0.2 times the capacity.
