    What I don't like about the video is the panick and misinformation about the sparks. I'm 99% sure they came from bad welding technique (bad contact, wrong parametres) and had nothing to do with used cells.

    One major thing missing in the video that probably should be there: The cells themselves. You cannot just replace any 18650/18490/18350/20650/something with just any same size cells. REPLACING CELLS WITH DIFFERENT ONES MIGHT BE DEADLY DANGEROUS! There is a reason why with 18650's and other cells not only capacity and voltage is mentioned but also rated amperage. Those two later ones are EXTREMELY important. Voltage just tells the voltage class the cell is, 3.7V 18650 cell optimally works between 4.2-3.4V depending on remaining charge, this is why your lithium AA/AAA rechargeable batteries don't tell in their case that they are 1.5V but 1.2V because they are 1.2V class cells.
     
    Amperage on the other hand tells you how many amps the cell is rated to give out. This is the point where safety really comes in and patience. Choosing between 1.2V, 3.7V and whatever voltage classes is easy because that is often told in the description because too low voltage and your device won't work and too high voltage your device will fry. Amperage is what tells at which point the cell is safety use and at which point it goes nuclear. Reputable cell manufacturers and shops will tell you two different amperage for a cell: continuous and peak meaning the safe amps the cell is rated to give out as long as there's charge and the safe amps the cell can give momentarily, the first one being the more important one often. Now when you take your battery pack open and you see the cells it's made from, look at them and try to find out their maker and model, often printed on the cell casing itself and should be visible through the wrapping. You will most likely find Sony/Murata cells (US18650[model]), Samsung cells (INR18650-[model]) or LG cells (LGDB[model]1865) (or other ones, these were just ones close around me to give examples). Now that you know what cells you are replacing try to find matching cells because if you replace something like Sony/Murata 18650VTC5A cells with something like LG MJ1 cells, you are going to die, because VTC5A is rated 25A/35A (up to 50A) and MJ1 is just 10A continuous and we don't need to go any further to know that your device might be same as short for the MJ1 cells and they will go nuclear.
     
    Most likely you are not going to die and the cells won't go nuclear if you F'ed up and put wrong ones in. But I will use those terms because these are things where not doing the groundwork and not being careful might end up with fire and explosions with burned homes and dead bodies.

    7/10 I like the composition and the choice of black and white with lots of contrast, but I think the depth of field is a little too shallow.

    6/10, great idea and I think it has the possibility to be a really cool image! It doesn't look like it's quite in focus and more emphasis on the Corsair logo would have made it a bit better for me, along with some more LEDs round the rest of the case

    And dont tell me that the difference is the one image being colored and the other black&white.

    Great exposure and location, you got the shutter speed just right too - clouds look brilliant against the buildings! Only thing I don't like as much is the reflections all around the car, but there's not much you can do at night to help that. 9/10
