Using & Testing Battery Hookup's Fused Nickel Strips - 1043 

It is slow blow fuse. It will blow at 8A or whatever it was rated for only if You draw that much for a prolonged time. It can take short bursts of much higher current.

DUI= driving under influence DIY= do it yourself what else do you do down there when the camera isn't rolling :p

Its normal. Short current is higher when meassured like that. Every fuse takes 5-10* the current during very Short bursts :)

And you dont fuse total current on cell level you do that eith the Main fuse. Set that to 15a it you like. You dont want all those small fuses to blow. You want a single fuse to burn ;)

And so the fuses will do essentially nothing, unless you have a DEAD SHORT CIRCUIT across one cell? I think, those fuses are almost useless. When was the last time you had a DEAD SHORT CIRCUIT across one cell? If 6 Amps can continuously flow into a weak cell, then it will eventually catch on FIRE, before its fuse will blow.

Kapton tape. I would pronounce that as "cap" and "ton". With regards to fuses, some fuses are designed to temporarily take more amps. It would be interesting to gradually increase the current and let it sit for a while. It may be that the fuse blows after 20 seconds at 10amps. Have a great day!

20A is not much considering there are 35A capable 18650 cells like SONY VTC6

20 amps. Well, if you ask Tesla motors they don't consider it out of the usual. Though, most 18650 cells don't actually like providing more than 3-5 amps continuous. One can go a bit higher if one provides some active cooling. And for a short burst, one can go a lot higher, though with noticeably reduced efficiency. Though, to be fair here. Building a battery bank for UPS-ish applications out of Lithium is going down the path that lithium really isn't ideal for. Due to its tendency to degrade itself by just being around, its high price per kWh (in your case its low due to second hand cells), and the weight reduction compared to lead acid isn't majorly important. Lead acid on the other hand loves being fully charged and are technically superior for UPS applications, especially at its much lower price per kWh and fairly comparable power density. Downside with lead acid is though that all battery packs one can easily buy are frankly abhorrently made, lacking both cell balancing, and then most lead acid batteries are discharged beyond what they actually like. (A given cell should never go bellow 1.85 volts) Then there is also the issue of "maintenance free" batteries, that generally die even faster since they barely contain enough electrolyte from the factory, and just a few charges and they start to get crippled. (in short, car batteries are garbage.) In your case, you use recycled cells, that are somewhat hanging on on their last legs regardless. Reuse is after all one of the more important steps in recycling.

You should install a small tv up on the wall (or a tiny "media" pc to play movies or tv shows off your nas), down there in the basement. It would make tedious projects like doing the fuse wire a bit more tolerable. It could also be a new video idea. : )

Can I donate and convert you to coke... freeway coke yuck. I only drink coke not pepsi and not diet either... hows the sugar effect your nice teeth ?? dont want all the time and money you spent on them years ago going to waste.

Those new fuses seem really over rated, maybe cut or use a dremel tool to grind a V notch in the strip to provide a single point for it to fail. I don't like the look of the bright red hot effect, too much like a heating element :-( Keep tinkering mort, you will win :-D

You can buy that in 5s an run one strip all the way down the battery pack then solder a bus bar on it then put a lug on it. Average joe an Pete tested those fuses they pop around 8 amps. They make the build a whole easier bee using them on my 7s batterys.

Great video where did you get your spot welder what model how much cheers

cut one of the tabs that is connected to the battery that should half it to 10A

Just bought that spot-welder via your link, that thing looks very nice. Ty for the recommendation!

I read the thumbnail as "You can moon on fly to the 20 amps"

But what about cell balancing if we short all positive side and negative sides?

I would not use those fuses they are super nice, but I like to use 2 amp fuse wire or less. I like your single strand way better than the new ones. Not a fan of that much heat possible in the bank that could melt something.

You can heat the house with that 20A 😂

I bought another brand which almost worked but didn’t so it went back. When I next feel like making battery packs I might try the super capacitor and copper rod method

The flames are the nickel burning off as its nickel coated

Yes weekend again, wow stuff.....
