5Pcs 3S 20A BMS 18650 Li-Ion Li-Ion Battery Charger Module

Detailed Information About The Product:

1. BMS 3 series 12.6V 20A lithium battery protection board (with recovery function - AUTO Recovery)
2. Scope of application: lithium batteries with nominal voltages of 3.6V and 3.7V (including 18650, 26650, and polymer lithium batteries)
3. This product is an enhanced version: suitable for electric drills with a starting current below 60A.
4. It can meet various performance requirements to ensure that the battery pack is absolutely safe and reliable
5. Application: vacuum cleaner, massager battery pack, LED light backup power supply, 12V electronic products, solar street light battery pack, monitoring backup power supply, etc. Wish Tags: lithium battery charger module, BMS protection board, PCB protection board, 18650 lithium battery, small pcb board

Maximum output current:20A
Quiescent current: less than 30uA
Charging voltage: 12.6V-13.0V
Continuous discharge current(upper limit):20A (if the heat dissipation environment is not good, please reduce the load current)
Continuous charging current(upper limit):10A
Enhanced version: suitable for electric drills with starting current below 60A and power below 100W.
Note 1: 3 15C-20C power batteries, or 6 10C-15C power batteries are needed to start the electric drill successfully (ordinary 18650 cannot start the electric drill!!); if the battery is too small or the power of the electric drill is too large If some cause cannot be started, please contact the owner to tell you the solution.
Note 2: Strictly connect 0V, 4.2V, 8.4V, 12.6V according to the diagram, and do not intentionally short-circuit.
Note 3: When there is a load with a brush motor, a capacitor (10uF-1000uF) must be connected in parallel with 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 3 groups of batteries are connected in series, please ensure that the voltage of each group of batteries is the same. If not, please fully charge each group of batteries separately and then use them in series.
