Properties of 2 strings of 6.4V lithium iron phosphate protection board: Model: HX-2S-D01 Overcharge voltage range: 3.65v±0.05v Size: 41*16*3.5mm Over discharge voltage range: 2.0-2.5v±0.05v Upper limit working current: 8A Working temperature: -40—+50℃ Upper current limit: 10A Storage conditions: -40– +80℃ Quiescent current: less than 10uA Effective life: more than 50000 hours Internal resistance: less than 300mΩ Short circuit protection: can be protected, need to be charged to restore Charging voltage: 7.2V-8.4V Properties of 2 strings of 7.4V lithium battery protection board: Model: HX-2S-D01 Overcharge voltage range: 4.25v±0.05v Size: 41*16*3.5mm Over-discharge voltage range: 2.9v±0.05v Upper limit working current: 8A Working temperature: -40—+50℃ Upper current limit: 10A Storage conditions: -40– +80℃ Quiescent current: less than 10uA Effective life: more than 50000 hours Internal resistance: less than 300mΩ Short circuit protection: can be protected, need to be charged to restore Charging voltage: 8.4V-9V Welding point description: ·B+ is connected to the positive pole of the battery; ·B- connect to the negative pole of the battery; ·MB is connected to the connection point before battery 1 and battery 2; P+ is connected to the positive electrode of the charging/discharging terminal (the charging terminal and the discharging terminal are shared); · P- is connected to the negative pole of the charging/discharging terminal (the charging terminal and the discharging terminal are shared). Reminder: When assembling the battery pack, the battery voltage, capacity and internal resistance should be well matched. The battery voltage should be around the rated voltage of 3.7V. There is no output after the battery pack is assembled, and it can be charged with 8.4V voltage. Common problem 1. Can my battery use your protection board? A: There are two issues to consider whether you can use this protection board: First, how many strings your battery is, you must buy a protection board corresponding to the number of strings. Second, what material is your battery made of? We have protection boards for lithium iron phosphate and polymer lithium batteries. If your battery is a lithium iron phosphate single-cell nominal 3.2V, you need to choose lithium iron phosphate 3.2V in the classification. If it is a polymer (ternary , cobalt acid, lithium manganate battery) single-cell battery nominal 3.6V (or 3.7V), please select the classification of polymer 3.7V. 2. How can I tell what material my battery is made of? Answer: You can look at the nominal voltage of your battery. Lithium iron phosphate batteries are generally marked with 3.2V, and other batteries are generally marked with 3.6V or 3.7V. You can also directly ask the seller of the battery what material the battery is. 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 A protection boards should I choose? Answer: How many A protection board to choose depends on the power of your product or the current limit of the controller, for example, choose 10A for below 100W, 20A for below 200W, 25A for below 300W, please contact customer service for above 500W, the current of the protection board Cannot be less than the controller current limit. 4. My battery is 20AH, can I use this protection board? Answer: The capacity of your battery is not directly related to the current of this board. Large capacity does not mean that the battery is large, but mainly depends on the continuous current. That is to say, the greater your power, the more continuous current you choose for the protection board. The bigger it is, it has nothing to do with your battery capacity. 5. How should the charger voltage be set? Lithium batteries should be charged with lithium battery chargers. Do not use lead-acid battery chargers. Lead-acid charging may cause high voltage to break down the MOS tube of the protection board, 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 the number of battery strings * 3.60V, this is the charging voltage of iron lithium battery, charging current standard 0.2 times the capacity.
