Vacuum cleaner adapted for Dayou 20v battery and Dreame v12 motor (c2022 M12-F-2 model motor)

Similar to the original author's model, it requires many 3mm self-tapping screws of various lengths. There are also many printed parts. The dust collection bin is the same as the original author's, and the battery pins are also the same as the original author's (Dayi A3 can also be used, but it needs to be sanded to match the battery)

For accessories and wiring, please refer to the attached images below

1. The motor used is the Dreame v12 motor (c2022 M12-F-2 model motor). The original drive board has a protocol, so the original drive board needs to be removed and an ESC used for speed control.
2. The front half is largely similar to the original author's model. In the latter half, the entire handle is removed, and the entire battery, including the battery holder, is moved downwards, and the battery holder is enlarged to accommodate electronic control components such as the ESC.
3. Adaptations have been made for the dust collection bin and cyclone dust collector. The flange within the printed model is connected to the main unit with a bayonet mount (the bayonet mount is the same as the original author's model). The flange size is a standard DN65 flange.
4. The main unit is connected to the dust collection bin or cyclone dust collector with a flange. Most cyclone dust collectors on MakerWorld do not come with a flange, so you might need to create a flange yourself to adapt it to the cyclone dust collector model.

Important Notes:

1. Pay attention to the positive and negative poles when wiring; do not reverse them. Otherwise, it will burn out the ESC and other drive boards.

2. The wiring of the Dayou battery does not include any protection, such as undervoltage protection, short-circuit protection, overcurrent protection, over-discharge protection, overcharge protection, etc. (Dayou batteries are protected by the battery's D-pin communication protocol)

   Requires: A 20v tool lithium battery undervoltage protection board, which triggers undervoltage protection below 15v.

   A medium-sized automotive fuse to prevent overcurrent and short-circuits from damaging the battery.

   I use an ESC without self-check. Alternatively, you can ask the ESC vendor to set the ESC undervoltage protection to trigger below 16v.

In summary, it is not recommended for those without DIY skills!!!
