Those parallel and series connections were like japannes alphabets..

I finally understand series connections on odd layouts thanks to your video! Thank you for the great information!

Wow! Another awesome built! Thank you for all the learning you shared with me. The way you put things together is in superb method. Idol!!!

Yep we need more/better options for building batteries! Better nickel, strip or grid, I think cell fuzing is mostly a false sense of security, or scared'ity! Because even with it fully fuzed, you can still have quiet the scare, the pack can go to meltdown! The main thing is to have a good BMS, that will stop a cell overcharging, and over tempature pack, heat and cell voltage is the main cause of meltdown, . About the only other cause is cell damage! Nice work! I'm looking for a smaller simple spit welder, I built a larger combersome welder, it works well, it's just difficult! I'm in the process of rebuilding! I have about 2000 cells to put together! Good day!!!

Awesome man. After a long time, I watched a video without skipping.

I think such big arrays of lithium batteries need some thermal control and ventilation

Enjoyed your video with my Morning cup of tea ! Amazing video brother!

[vivekyadav]

Just be careful measuring the size of cell using a vernier :)

[FlipskyTech]

Owesome, that's really pretty pretty video of battery pack building, Also really cool spot welder FS-SW1!

[welchianachi]

Magic will start when you will use metal caliper for measurement.

[oldschool]

That's going to be one hella vape mod

[soulzzplaysgames]

I have a feeling something like this will get a bit warm while using.

[TheBlargMarg]

It's like a exciting and dangerous game of Tetris where if you fail you potentially either burn down your house or worse pack of batteries explode.

Thanks for making my vape batts cheaper m8 👍

[halohub]

What about vibratrations on the battery? Not using cell dividers could cause the battery wrapping to wear away between the series coneections and cause a short? Tjose little rubber spacers enough?
