3 Strings 11.1V 12.6V Lithium Battery Protection Board Overcharge Overdischarge 10a Current Limiting

(Description in Chinese and English for Details)

Description in Chinese:

Note:

This Protection Board Cannot Be UsedLithium Iron Phosphate Battery, Xenon Lamp, Electric Hand Drill Battery Pack, Electric Fish Machine Battery Pack, Battery Pack of Electric Bike, Perambulator Battery, Motor above 775 (4a), 1W Fisheye Led Light, Customers Who Purchase the above Combination Please Pay Attention!.

The Power Range Described Applies to the following Products:

Massager Battery Pack, LED Lamp Standby Power Supply, 12V Electronic Products, Solar Street Lamp Battery Pack, Monitoring Standby Power Supply, and Other Products.

Note: for Products with Discharge above 3A Current, the Battery Discharge Rate Should Be above 3C.

Rate Calculation Formula: for Batteries with 1C Rate, 2000 Capacity Is Equal to 2AH * 1 = 2a Upper Limit Work Current.

3C Rate Battery, 2000 Capacity Equal to 2AH * 3 = 6A Upper Limit Work Current.

In Use, the Battery Will Heat up, but the Battery Rate Is Not Applicable. in This Case, It Cannot Be Used for a Long Time and the Battery Will Be Damaged Quickly.

Note 1: Wiring 0V(B-), 3.7V(B1), 7.4V(B2), 11.1V(B) in Strict Accordance with the Figure, Do Not Deliberately Short Circuit!

Note 2: After Connecting the Cable, You Need to Charge It First before the Output Can Be Generated.

Note 3: When Connecting Three Groups of Batteries in Series, Please Ensure That the Voltage of Each Group of Batteries Is the Same. If Not, Please Fill Each Group of Batteries Separately and Use Them in Series. During the Discharge Test, the Group of Batteries with the Fastest Voltage Drop Is Poor Batteries.

Note: Do Not Mix Good Batteries with Poor Batteries! the Closer the Capacity/Internal Resistance of the 3 Groups of Batteries Is, the Better! (2 One Good Battery 1 One Poor Battery Use Effect = 3 One Poor Battery Use Effect).

Faq

1. Can My Battery Use Your Protection Board?

Answer: There Are Two Questions to Consider Whether You Can Use This Protection Board: First, How Many Strings of Your Battery Are, You Need to Buy a Protection Board Corresponding to the Number of Strings. Second, What Material Is Your Battery? We Have Two Parameters of Lithium Iron Phosphate and Lithium Polymer Battery Protection Board, If Your Battery Is Lithium Iron Phosphate Single Section Nominal 3.2V Need to Choose Lithium Iron Phosphate 3.2V in the Classification, If It Is Polymer (Ternary, Cobalt Acid, lithium Manganite Battery) for a Single Battery, Please Select the Classification of 3.7V Polymer for the Nominal 3.6V (Or 3.7V).

2. How Do I Judge What Material My Battery Is?

Answer: You Can Look at the Nominal Voltage of Your Battery. Lithium Iron Phosphate Batteries Are Generally Marked 3.2V, While Other Batteries Are Generally Marked 3.6V Or 3.7V, you Can Also Directly Ask the Seller Who Sells the Battery What Kind of Material the Battery Is. Many Buyers Say That My Battery Is 18650 Or 26650 Soft Pack, Etc. This Is the Appearance, Not the Material! We Cannot Determine Your Battery Protection Parameters Based on This.

3. How Many Protection Boards Should I Choose?

A: The Number of Protection Boards Selected Depends on the Power of Your Product Or the Current Limiting of the Controller. for Example, If You Choose 10A below 100W, If You Choose 20A below 200W, If You Choose 25A below 300W, for More than 500W, Please Contact This Wangwang First. the Current of the Protection Board Cannot Be Less than the Current Limiting of the Controller.

4. My Battery Is 20ah. Can I Use This Protection Board?

a: the Size of Your Battery Capacity Is Not Directly Related to the Current Size of the Board. the Large Capacity Is Not the Large Battery, but Mainly Depends on the Continuous Current, That Is to Say, the Larger Your Power Is, the Larger the Continuous Current of the Protection Board You Choose, It Has No Direct Relationship with Your Battery Capacity.

5. How Should the Charger Voltage Be Set?

the Lithium Battery Should Be Charged with a Special Charger for Lithium Battery. Do Not Use Lead-Acid Battery Charger. Lead-Acid Charging May Have a High-Voltage Breakdown Protection Board of Mos Tube, Causing the Protection Board to Be Overcharged without Protection.

Charger Voltage Setting: Use Your Battery Pack String Number * 4.2V This Is Not Lithium-Ion Battery Charging Voltage, Lithium-Ion Battery Charging Voltage Is Battery String Number * 3.60V This Is Lithium-Ion Battery Charging Voltage, the Charging Current Standard Is 0.2 Times the Capacity.
