Solder point description.
B+ connects to the positive terminal of the battery
B- connect the negative terminal of the battery
MB connects to the connection point before battery 1 and battery 2
P+ connects to the positive side of the charge/discharge terminal (charge/discharge terminal shared)
P- connects to the negative side of the charge/discharge terminal (shared between charge/discharge terminal)
Warm tip: When combining battery packs, the battery voltage, capacity and internal resistance should be paired well, and the battery voltage should be around the rated voltage of 3.7V, and the battery pack should be charged with 8.4V if there is no output after the pack is set up.

Common problems:
1、Can I use your protection board for my battery?
A: There are two issues to consider if you can use this protection board: First, how many strings of batteries you have, you have to buy the corresponding number of strings of protection board. Second, what material is your battery? If your battery is a lithium iron phosphate single cell nominal 3.2V you need to choose the lithium iron phosphate 3.2V in the classification, if it is a polymer (ternary, lithium cobalt acid, lithium manganese acid) single cell nominal 3.6V (or 3.7V), please choose the polymer 3.7V classification.

2、How can I tell what material my battery is made of?
A: You can look at the nominal voltage of your battery, lithium iron phosphate batteries are generally marked 3.2V, other batteries are generally marked 3.6V or 3.7V, you can also directly ask the seller of the battery is what material battery, many buyers say my battery is 18650 or 26650 soft pack, etc., this is the shape, not the material Oh! We are unable to determine your battery protection parameters based on this.

3、How much A protection board should I choose?
A: How much A protection board depends on the power of your product or the controller current limit, for example, 10A for below 100W, 20A for below 200W, 25A for below 300W, please contact customer service first for above 500W, the protection board current cannot be less than the controller current limit.

4、My battery is 20AH, can I use this protection board?
A: The size of your battery capacity is not directly related to the size of the current with this board, the capacity is not a large battery, but mainly depends on the continuous current, that is to say, the greater your power, the greater the continuous current of the protection board you choose, there is no direct relationship with your battery capacity.

5、How should the charger voltage be set?
Lithium batteries should be charged with a special charger for lithium batteries, do not use a lead-acid battery charger, lead-acid charging may have a high voltage breakdown of the protection plate MOS tube, resulting in overcharging of the protection plate is not protected.
Charger voltage setting: use your battery string number * 4.2V which is the charging voltage of non-lithium iron batteries, the charging voltage of lithium iron batteries is the battery string number * 3.60V which is the charging voltage of lithium iron batteries, the charging current standard is 0.2 times of the capacity.
