Specification
- 1. Using high-quality materials, durable
- 2. Lithium battery protection board specially designed for lithium phosphate, ternary lithium battery, lithium cobalt oxide, lithium manganate battery pack
- 3. Adopt mature protection circuit, dedicated IC and support disconnection protection
- 4. High-quality high-current ultra-low internal resistance MOS (internal resistance of a single MOS is as low as 3 milliohms)
- 5. It has various protection functions for perfect and stable charging and discharging. The battery cell is balanced by hardware, the balance current is appropriate, and the balance heat is reasonable, which does not affect the performance of the battery pack.
- 6. Wide range of applications: lithium iron phosphate, ternary lithium battery, lithium cobalt oxide, lithium manganate battery pack
Parameter:
- Pin mode:
- P-: negative pole of load C-: negative pole of charger B-: negative pole of battery
Hands-on guide:
- Output current: separate port 80A; same port 60A
- Note: Lithium batteries should be charged with a special charger for lithium batteries. 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.
Description
Common problem:
1. Can my battery use this protection board?
A: There are two issues to consider whether you can use this protection board: how many strings your battery is, you need to buy a 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 lithium iron phosphate single-cell nominal 3.2V, you need to choose lithium iron phosphate 3.2V in the classification. If it is polymer (ternary, cobalt Acid, lithium manganate battery) If the nominal 3.6V (or 3.7V) of a single cell battery, 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 safety boards should I choose?
Answer: How many amps of protection board you choose depends on your load power. For our protection board, 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, and the power is about 600W.
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 the board. Large capacity does not mean that the battery is large. It mainly depends on the continuous current. That is to say, the larger your load, the more continuous current you choose for the protection board. The larger it is, it is not directly related to the battery capacity.
5. How should the charger voltage be set?
Answer: Lithium batteries must be charged with special 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.
The meaning of balance:
The battery pack uses a lot of cells in parallel and then connected in series, and the cells cannot be exactly the same, so when matching, only those with similar performance can be grouped together, but when charging, due to the different cells Inconsistent performance will lead to inconsistent voltage after charging is completed. Equalization is to discharge the high-voltage cells with resistors during charging, and wait for the low-voltage cells to charge up the voltage, so as to achieve the same voltage of each cell and improve the performance of the entire battery pack.
