2 ай бұрынI bought this not working EY503 2.4v battery screwdriver without a battery or a charger. Can I fix it and convert it to 3.6v Li-Ion?

¡Muy buen video!! Déjame comprender esto: ¿conectas B+/- a la batería, y dejas libres las conexiones OUT+/-? El motor se conecta directo a la batería? Ningún diodo desde la fuente al INPUT+? Gracias por tu excelente trabajo!!!

Sí. Conecto B+ y B- a la batería y conecto la batería directamente al motor. No uso la salida en la placa BMS porque la corriente será demasiado baja.

why didn't you use out+ put- for the motor? we risk discharging the battery because it is managed by the tp4056,right?

You cannot use TP4056 to manage output. The motor requires too much current so you have to connect direct to the battery.
