Dear friend, if there is no product you need on my shelf, please contact me.
Tips: This protection board can not be used in electric fish machines, such as xenon lamps.
Chinese and English labels are available.
3 string 11.1V high current 100A, 3.7V ternary lithium battery protection board with balanced charging.
The properties of the lithium battery protection board:
Model: HX-3S-F100A Overcharge voltage range: 4.28v±0.05v
Size: 70*60*8.5mm Over-discharge voltage range: 2.5±0.05v
Upper limit working current: 100A (pay attention to heat dissipation) Working temperature: -40---+50°C
Upper limit instantaneous current: 100-120A Storage condition: -40-- +80°C
Quiescent current: less than 30uA effective life: more than 30,000 hours
Internal resistance: less than 300mΩ Short circuit protection: protection, delay self-recovery.
Equilibrium current: 65 mA
Charging voltage: 12.6V-13V Charging current upper limit: 10A
T point description: Adding a normally closed temperature sensor switch can extend the temperature protection function, and the 0R resistor next to the solder joint should be removed.
Note: For discharge products above 3A, the battery discharge rate should be more than 3C.
Magnification calculation formula: 1C rate battery, 2000 capacity is equal to 2AH*1=2A working current.
3C rate battery, 2000 capacity is equal to 2AH*3=6A working current.
In the use of the battery will be hot, the battery rate is not applicable, this situation can not be used for a long time, the battery will be damaged quickly.
Note 1: Strictly according to the diagram wiring 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B +), C-charge negative, C + charge positive, P- output negative P + output positive, do not Deliberate short circuit!
Note 2: After the line is connected, it needs to be charged before it will have output.
Note 3: When connecting 3 sets of batteries in series, please ensure that the voltage of each set of batteries is the same. If they are different, please fill each set of batteries separately and use them in series. In the discharge test, the battery with a fast voltage drop is a poor battery.
Explain: Do not mix good battery and poor battery! The closer the capacity/internal resistance of the three batteries is, the better! (The effect of 2 good batteries + 1 poor battery = the effect of 3 poor batteries).
There are 10 MOS tubes, strong heat-dissipating aluminum sheets, and the continuous current limit is 100A. It is suitable for 3 series lithium battery packs such as inverter, xenon lamp and solar street lamp.
common problem
1. Can my battery use your 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 lithium polymer battery. 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 (three yuan) , 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 A protection boards should I choose?
Answer: How many A's protection boards are selected depends on the power of your product or the controller's current limit. For example, 10A below 100W, 20A below 200W, 25A below 300W, please contact Want Want before using 500W or more. The current cannot be less than the controller current limit.
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 capacity is not the battery, mainly the continuous current, which means that the higher your power, the continuous current of the protection board you choose will be The bigger it is, it is not directly related to your battery capacity.
5. How should the charger voltage be set?
Lithium battery should be charged with lithium battery special charger, do not use lead-acid battery charger, lead-acid charging may have high voltage breakdown protection board MOS tube, resulting in protection board overcharge is not protected.
Charger voltage setting: Use your battery pack number *4.2V This is the charging voltage of non-ferrous lithium battery, the charging voltage of iron-lithium battery is the number of battery strings *3.60V This is the charging voltage of iron-lithium battery, charging current standard It is 0.2 times the capacity.
