Specification
Pin mode:
P-: negative pole of load
C-: negative pole of charger
B-: negative pole of battery
Practical guide
Output current: separate port 80A; same port 60A
Note: Lithium batteries should be charged with special chargers for lithium batteries. Do not use lead-acid battery chargers.
Lead-acid charging may cause high-voltage breakdown of the protection board MOS tube, causing the protection board to be overcharged and not protected.
(1) 3-string split-port wiring method (refer to 3-string split-port wiring diagram)
① Connect the 3 battery packs in series according to the battery connection in the 3-string split-port wiring diagram.
④ Refer to the three-series split-port wiring diagram and use three wires to connect the positive poles of the three battery packs to B+, B4, and B3 in sequence.

(1) 3-string split-port wiring method (refer to 3-string split-port wiring diagram)
① Connect the 3 battery packs in series according to the battery connection in the 3-string split-port wiring diagram.
② Connect the negative pole of the charger to C- of the protection board, and connect the negative pole of the load to P-.
③ Connect the positive poles of the charger and the load to the positive poles of the three strings of batteries.
④ Refer to the three-series split-port wiring diagram and use three wires to connect the positive poles of the three battery packs to B+, B4, and B3 in sequence.
⑤ Connect the negative poles of the 3 strings of batteries to B-. B1, B2 and B- are shorted.
⑥ After all the wires are connected according to the 3-string split-port wiring diagram and check whether they are correct, they can be used only after confirming that they are correct.
⑦ During use, when the indicator light on the protection board is on, it indicates that the corresponding battery pack is in a
balanced working state (that is, the battery is unbalanced at this time).
⑦ During use, when the indicator light on the protection board is on, it indicates that the corresponding battery pack is in a

FAQ
1. Can my battery use this protection board?
Answer: There are two questions to consider whether you can use this protection board: How many strings are your batteries, you have to buy the protection board corresponding to the number of strings. Second, what material is your battery made of? We have protection boards with two parameters: lithium iron phosphate and polymer. If your battery is a single cell of lithium iron phosphate with a nominal 3.2V, you need to choose lithium iron phosphate 3.2V in the category. If it is a polymer (ternary, cobalt Acid, lithium manganate battery) For single-cell batteries 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 at 3.2V, and other batteries are generally rated at 3.6V or 3.7V. You can also directly ask the seller of the battery what material is the battery. 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 protective plates should I choose?
Answer: How many ampere protection boards you choose depends on your load power. Our protection boards, if you use split-port output, the output current is about 70A, and the power is about 800W. If you use the same port output, the output current is 50A, power It is about 6

4. Can my battery be used with this protection board if it is 20AH?
Answer: Your battery capacity is not directly related to the current using this board. Large capacity does not mean that the
battery is large. It mainly depends on the continuous current. That is to say, the greater your load, the continuous current of the protection board you choose. The larger it is, it has no direct relationship with the battery capacity.
5. How should the charger voltage be set?
Answer: Lithium batteries must be charged with special chargers for lithium batteries. Do not use lead-acid battery chargers. Lead-acid charging may cause high-voltage breakdown of the protection board MOS tube, causing the protection board to be overcharged and not protected. Charger voltage setting: Use your battery string number*4.2V, this is the charging voltage of non-iron-lithium battery, the charging voltage of iron-lithium battery is battery string number*3.60V, this is the charging voltage of iron-lithium battery, charging current standard It is 0.2 times the capacity.
