Every product has been professionally and rigorously tested before it leaves the factory, and the quality is strictly checked to ensure that you can use it with confidence.
The polymer is wired in the same way as lithium iron phosphate, supporting both the same port and split port.
Step 1; B-line to the negative of the lithium battery pack
Step 2; connect the cable (make sure the cable is unplugged from the protection board, start wiring from B-, 8-connect the total negative pole of the battery pack, the second line B1 of the cable is connected to the first string of the positive battery of the lithium battery pack) The third line B2 is connected to the positive pole of the second series of batteries of the lithium battery pack, followed by
Step 3: Insert the cable after checking the error.
Step 4: Take out the C line
Step 5: Whether the total voltage of the lithium battery is equal to the voltage of C-to the positive pole of the battery (the equivalent board is working normally)
This protection board supports a minimum of 6 strings. The following figure takes 7 strings as an example. It needs to be shorted as shown in Figure B7 to B+.
The B-, C-, and P- lines should be connected with thick wires and ensure that the pads are soldered correctly to the positive and negative terminals of the corresponding device.
Before installing the protection board, the battery must be matched well (the voltage difference between each battery is not higher than 0.05v, the internal temperature difference is not more than 5mΩ, the difference is less than 30mAh), the protection board is to protect each string of batteries, as long as there is a string of batteries If the voltage is too high or too low, it will be protected. The better the battery consistency, the longer the battery life, and the best performance of the protection board.
A single battery needs to be connected in parallel to the required number of battery packs, and then the battery packs are used in series.
When connecting the battery packs in series, please ensure that the voltage of each battery pack is the same. If it is different, please fill each battery pack separately and use it in series. In the discharge test, the circuit with the fastest voltage drop is the differential power.
Do not mix good batteries and poor batteries. The battery pack's sorrow and internal resistance are as close as possible.
The lithium battery protection board is used in series.
1. Can my battery use this protection board?
A: Can you use this protection board to have two questions to consider: First, how many strings of your battery, you have to buy a corresponding number of protection boards.
Second, what is your battery? We have a protective plate with two parameters of lithium iron phosphate and polymer. If your battery is a single lithium phosphate of 3.2V, you need to select lithium iron phosphate 3.2V in the classification. If it is a polymer (ternary, cobalt acid) , lithium manganese oxide battery) single battery nominal 3.6V (or 3.7V) please select the classification of polymer 3.7V.
2. How do I judge what material my battery is?
A: You can look at the nominal voltage of your battery. Lithium iron phosphate battery is generally 3.2V. Other batteries are generally 3.6V or 3.7V. You can also directly ask the battery of the seller who sells the battery. Many buyers say that my battery is 18650 or 26650 soft pack, etc. This is the shape, not the material! We are unable to determine your battery protection parameters based on this.
3. How many protection boards should I choose?
A: The number of protection boards to choose depends on your load power. Our protection board is the same port output. The maximum current of the output string is 16A, and the maximum current of the 2 series is 25A.
4. Can my battery be 20AH use this protection board?
A: The size of your battery is not directly related to the current of this board. The large amount is not the battery, mainly the continuous current, which means that the larger your load, the continuous current of the protection board you choose will be The larger, it is not directly related to battery capacity.
5. How should the charger voltage be set?
Answer: Lithium battery must be charged with lithium battery charger. Do not use lead-acid battery charger. Lead-acid charging may have high-voltage breakdown protection board MOS tube, resulting in over-protection of protection board. Charger voltage setting: Use your battery pack number *4.2V This is the charging voltage of the non-ferrous lithium battery. The charging voltage of the iron-lithium battery is 3.60v. The charging voltage of the iron-lithium battery is the charging current standard. 0.2 times the capacity.
