| + | [title] Optional: remove the new batteries protection circuit |
|---|---|
| + | [* black] If you have found new, unprotected 18650 batteries - congratulations! skip to the next step |
| + | [* black] ***WARNING:*** the protection circuitry is there for a reason. Shorting an unprotected battery will result in sparks and overheating. |
| + | [* black] Why do we need unprotected batteries: |
| + | [* black] the protection circuitry, among other things, disconnects the battery if it's being shorted (i.e. the discharge current is over a certain threshold). |
| + | [* black] as a result, when the vacuum tries to pull the current necessary to run the quite powerful motor, the battery protection circuitry shuts down preventing normal operation |
| + | [* black] To compensate for the missing battery protection, the vacuum has airflow cooling for the batteries, as well as a thermal sensor (which is what I think the red wire glued between the batteries is, see photo) which should shut it down in case of overheating. |
| + | [* black] Also, the protection circuitry adds an extra 2mm to the battery tallness, which means that protected batteries don't fit in the battery assembly housing |
| + | [* black] Follow any tutorial on Youtube about "how to remove 18650 protection". For example [link|https://www.youtube.com/watch?v=H75cYVbvRyo|this one] |
