3s 60A balanced BMS PCM 18650 lithium battery protection board

60A 3S BMS Circuit 12V 60A Protection Circuit 12V BMS 60A 11.1V 12.6V 18650 AA AAA Lithium Battery Charging Board 3S 60A BMS Circuit 12V BMS Battery Management System

This is a 3S 12V 60A 18650 lithium battery protection board with 11.1V 12.6V high current and balanced circuit overcharge, overcurrent, and short-circuit protection functions. The charging and discharging of the board are the same port, and the board contains a balancing circuit.
When the charging is balanced, the circuit board will be a bit hot, and even after disconnecting the charger, some will still be in a balanced state, continuing to heat up for a period of time until it is below the balance breaking threshold.
This protective plate cannot be used for the protection of iron lithium polymer batteries (for other batteries, regardless of the material, as long as overvoltage and discharge voltage can be used for cutting), electric finished machinery, electric bicycle batteries, automotive and motorcycle starter batteries.
Applicable to the following products (within rated power):
Electric drill, 775 motor (6A-10A), low-power inverter, low-power vacuum massager battery, LED light, 12V backup power electronic products, 12V120W car wash pump, battery, solar street light monitoring backup power supply and other products.
The rated current cannot exceed 40A, and it cannot exceed 60A every 0.5 seconds.

Welding point description:

B+: Connect to the positive pole of the battery
B -: Connect the negative pole of the battery
BM: Connect battery 1 and battery 2 connection points
P+: Connect the charging/discharging side of the positive terminal
P -: Connect to the negative terminal on the charging/discharging side
Preventive measures:

Strictly follow the wiring diagram: 0V (B -) 3.7V (B1) 7.4V (B2) 11.1V (B+), do not intentionally short circuit.
After the circuit is connected, it needs to be charged first before there is output.
When three groups of batteries are connected in series, please ensure that the voltage of each group of batteries is the same. If they are not the same, please fully charge each set of batteries before use.
Do not mix good batteries with batteries.
The closer the capacity and internal resistance of the battery, the better.
Caution: Do not mix good and bad batteries. The closer the capacity and internal resistance of the three batteries are, the better.
Please ask the buyer to understand the professional knowledge of this module before purchasing
