Hello World!

It's Finland calling!

Here, up in the North, you know, #Lapland, #ArcticCircle, reindeers, Santa Claus etc.

For the 3rd week, this is how the #weather is like in here. The #heat limit here is 25 °C.

Today yet another record was broken - it has been 19 days that the #temperature has been above 30 °C somewhere in #Finland. And tomorrow it'll be 20 since this map is for tomorrow afternoon.

You think #ClimateChange isn't real?

Well, think again.

It has taken me about 12 minutes to cool down an 18650 battery which was heating up, that it was almost too warm to the touch. The battery was in the charger which clearly doesn't properly communicate with the BMS, creating a fairly dangerous situation
The battery in someone else's hand could have spontaneously combusted into flames igniting the charger and then the wood of the table it was standing on.
I have a habit of standing up, way in the depths of the night, either because I want to go training on my race machines, or because I want to physically feel how warm the batteries are that I'm charging.

Today I'm very glad that I routinely do this, because the BMS failed, a temperature sensor is obviously absent in the charger, and the chemicals would have potentially created a runaway situation because the battery was running this hot for at least a couple of hours!

The 18650 cell delivers the energy that is needed just fine it just cannot charge to 100% anymore

Of course I have marked the cell, so I can now manually remove it from the charger
