အဓိကသတင်းအချက်အလက်

Country of Origin : China
Description :3 strings of 11.1V 12V 12.6V 18650 lithium battery charging protection board

Descriptions
1. BMS 3-string 12.6V 20A lithium battery protection board (with built-in recovery function-AUTO Recovery)

2. This product is an enhanced version: suitable for electric drills with a starting current of less than 60A.

3. 3 strings of 12.6V 20A lithium battery protection board (with recovery function - AUTO Recovery)

4. Scope of application: lithium batteries with nominal voltages of 3.6V and 3.7V (including 18650, 26650, and polymer lithium batteries)

5. Product size: 59*20*3.4mm

6. Product weight: 4.3g

7. Charging voltage: 12.6V - 13.0V

8. Continuous discharge current (upper limit): 20A (if the heat dissipation environment is not good, please reduce the load current)

9. Continuous charging current (upper limit): 10A

10. Standard version: suitable for electric drills with a starting current below 40A and power below 65W.

11. Enhanced version: suitable for electric drills with a starting current below 60A and power below 100W.

- Note 1: Three 15C-20C power batteries, or six 10C-15C power batteries are required to successfully start the electric drill (ordinary 18650 cannot start the electric drill!!!); if the battery happens to be too small or the power of the electric drill is too high Some of them cannot be started, please contact the store owner to tell you the solution.

-Note 2: Wire 0V, 4.2V, 8.4V, 12.6V strictly according to the diagram, do not short circuit intentionally.

-Note 3: When there is a load with a brush motor, a capacitor (10uF-1000uF) must be connected in parallel to the positive and negative terminals of the motor to prevent the reverse peak voltage generated by the motor from interfering with the protection board or breaking down the MOS tube.

-Note 4: 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 charge each set of batteries separately before using them in series. . .

- During the discharge test, the battery group whose voltage drops faster is a bad battery.

- Explain to some customers with poor electronic foundation: don't mix good batteries and bad batteries together! The closer the capacity/internal resistance of the 3 batteries is, the better! (The effect of using 2 good batteries + 1 bad battery =The use effect of 3 poor batteries).

Package Include
