| [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 we're doing this: | |
| [* 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) 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 without removing the protection it's impossible to fit them in the battery assembly housing |
