Para conectar 1 sola batería tipo 18650

Funciones principales: protección contra sobrecarga, protección contra sobredescarga, protección contra

cortocircuitos, protección contra sobrecorriente.

Antes de instalar la placa de protección, la batería debe coincidir bien (la diferencia de voltaje entre cada batería no debe ser de 0,05 V, la diferencia de resistencia interna no es superior a 5mQ, la tolerancia es inferior a 30mAh), cuanto menor sea la diferencia de voltaje de la batería, mejor funcionará la placa de protección.

Conexión:
B + Conectar borne positivo de la batería
B - Conectar borne negativo
P + Conexión servicio Carga/Descarga (negativo)
P- Conexión servicio Carga/Descarga (positivo)

Precautions: Before installing the protection board, the battery should be matched well (the voltage difference between each battery should not be 0.05V, the internal resistance difference is not more than 5mQ, and the tolerance difference is less than 30mAh).

The smaller the battery voltage
difference is, the better the protection board will work. The batteries are connected in parallel and then connected in series, and the welding is correct (18650 battery nickel spot welding, other batteries
are soldered), do not screw, easy to burn the protection board IC. If it is an old battery change board, please pay attention: Please confirm whether the battery is normal before buying.

When installing,use a multimeter to check whether each string of battery voltage is the same

The performance failures with a difference of more than 1.0V are: running not far, starting and powering off, charging time is short, basically the battery core problem is more. The failure of the protection board is as follows: the battery cannot be charged, and the battery has a voltage and cannot be discharged.
