describe:
Product Name: 3 string 14.8V 16.8V 40A lithium battery protection board
312.6V 40A lithium battery protection board (with recovery function-AUTO Recovery)
Scope of application: nominal voltage of 3.7V lithium battery (including , 26650, polymer lithium battery)
Product size: 41*55*3.4mm (enhanced version), 41*60*3.4mm (balanced version)
Product weight: 8.8g (enhanced version), 9.8g (balanced version)
Charging voltage: 12.6V-13.6V Continuous discharge current (upper limit): 40A (if the heat dissipation environment is not good, please reduce the load current) Continuous charging current (upper limit):
20A enhanced version: suitable for electric drills with starting current below 80A and power below 130W. (Without balance function)
Balanced version: suitable for electric drills with starting current below 80A and power below 170W. (With balance charging function)
Note 1: 15C-20C power battery 3 pieces, or 10C-15C power battery 6 pieces (normal batteries can not be drilled!!).
Note 2: When wiring 0V, 4.2V, 8.4V, 12.6V, please strictly follow the wiring diagram and do not intentionally short-circuit.
Note 3: When the battery is charging, the "430" resistor heats up normally, indicating that the balance circuit is working. If the "430" resistor does not charge and heats up, please check whether it is connected to the wrong wire.
Note 4: Do not mix good batteries and low-quality batteries, please make sure that the capacity and internal resistance of each battery are the same.
For some electronic customers with poor basics, explain: Balanced charging is only an auxiliary function, try not to mix good batteries with bad batteries! The closer the capacity/resistance of the 3 groups of batteries, the better! (2 good battery + 1 poor battery use effect = 3 poor battery use effect).
