Makita 7.2V Grass Shear Restoration & Build New Li-ion Battery | MUM 105D 

😢 cái dụng cụ cắt tỉa này nhỏ quá làm việc không có năng suất 😂😅

Its just for balancing the cells when charging

@@sergaljesus Absolutely not. That wires send power to the BMS as well. Otherwise how the tool will power up if there are no wires connected from the motor to the battery. The only wires from the motor are connected to the BMS, and the BMS takes power from the battery through those thin wires as well

Wire gauge is chosen to suit expected current flow. These are "sense" wires that let the BMS see voltages during balancing, they don't flow any high currents.

@@sergaljesus You are correct. You only need the heavy gauge wires for when the battery power is being used

@@yeagerxp Following your way of thinking, if the orange wires are just for cell balancing, if I remove them the tool will work anyway, right? Wrong, that wires are for cell balancing and power on that BMS style. Use thicker motor wires is useless if the power from the battery is taken from thinner wires

I'm always feeling surprise with Japan tools, they make a lot of tools.

@@gear_show Me too! And I agree. Seeing all of the unique Japan tools is part of the reason why I like your videos so much. Much appreciated from 🇨🇦
