3S 60A 18650 Balanced BMS with Protection Board

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

This is 3S 12V 60A 18650 Lithium Battery Protection Board 11.1V 12.6V High Current With Balanced Circuit Over Charge Over-Discharge Over Current And Short Circuit Protection Function. Board charging and discharging are the same port, the board includes the balanced circuit.
When the charge balance, the board will be a bit warm, even after disconnecting the charger, some are still in the balance, will continue to warm for a while until below the equilibrium break threshold.
The protection board cannot be used for iron lithium polymer battery (for other batteries, no matter what material, as long as the overvoltage and put voltage can be used for cutting), electric finish machinery, electric bicycle batteries, car, and motorcycle starter battery protection.

Applicable to the following products (within rated power):
Electric drill, 775 motors (6A-10A), small power inverter, small power vacuum massager battery, LED lamp, 12V standby power electronic products, 12V120W car washing pump, battery, solar street lamp monitoring standby power supply, and other products.
Rated current can’t over 40A, it can’t exceed 60A per 0.5 seconds.

Welding point Description:

• B+ : Connect to the battery positive

• B- : Connect to the battery negative

• BM: Connect to the battery 1 and battery 2 joining point

• P+ : Connect to the charge / discharge side of the positive terminal

• P- : Connect to the charge / discharge side of the negative terminal

Precautions:

• Strictly according to the diagram wiring: 0V(B-)3.7V(B1)7.4V(B2)11.1V(B+), Do not deliberately short circuit.

• After the line is connected, Need to charge first, then have output.

• When the battery is connected in series with 3 groups, Please ensure that the voltage of each battery is the same. If not same, please fill in each set of batteries and then use.

• Do not mix the good battery and the battery.

• The capacity of the battery internal resistance is closer will be better.

• Attention: Do not mix the good battery and poor battery to use. The internal resistance of 3 battery capacity are closer will be better.

• Please buyers know the professional knowledge of this module before buying
