Ebikes, bicycles, scooters, skateboards, longboards, eboards, motorcycles, skates, unicycles: Whatever floats your goat, this is all things micromobility!

"Transportation using lightweight vehicles such as bicycles or scooters, especially electric ones that may be borrowed as part of a self-service rental program in which people rent vehicles for short-term use within a town or city.

micromobility is seen as a potential solution to moving people more efficiently around cities"

It's a little sad that we need to actually say this, but:

Don't be an asshole or you will be permanently banned.

Respectful debate is totally OK, criticizing a product is fine, but being verbally abusive will not be tolerated.

Focus on discussing the idea, not attacking the person.

Can you explain what is meant by a "4C charging rate"?

[–] ch00f 2 points 1 week ago* (last edited 1 week ago) (1 children)

The current a battery can accept/provide tends to scale with the size of the battery. So rather than measuring it in Amperes, it's usually measured in C. 1C means that the battery will be full charged or discharged in 1 hour. 4C means it'll be charged in 1/4 hour. The charge rating tends to be lower than the discharge rating though it depends on the cell.

Basically, you take the battery capacity and divide it by the charge rate. If you exceed the C rating of the battery, it could cause it to overheat or even catch fire.

When it comes to higher performance requirements (like in drones), you can get insanely high C rates like this though those batteries aren't typically designed to survive too many charge/discharge cycles.
