I see this formula for ampacity of busbar for DC current I_CCC = K*busbar width*bus bar thickness Is it really this simple? Where K is a constant depending on if you are using copper or aluminum. This equation seems to simple to me. Additionally, I can't find anything with regards to the...

Different power tool batteries have different BMSs, as well as connector to connect to their brand of power tools. So the only thing that can be modular between one brand and the other is the actual cells. I know that there are converters to change for exmaple the Makita connector to a Milwaukee...

I have a couple of questions with regards to using different model cells of different capacities within a single battery pack, but the same chemistry and at the same voltage. Note I am NOT suggesting that anybody does this or does anything unsafe. I'm simply asking a question to understand a...

Hello Freinds I have a power tool BMS whose rated continuous discharge current is 35 A. So per Matador's ampacity table that is cited on these forums in many places, 0.1 mm thick by 10 mm wide strip, 13 of them stacked would give me 36.48 A. Now the B- and B+ holes within the PCB, can't fit...

I'm simply trying to understand how to select nickel strip for my battery pack. Note that I'm just simply trying to understand the math here only and the concepts behind selecting nickel strips, and nothing more. I'm not suggesting anyone do anything unsafe. I'm building a 5S3P Li-Ion pack from...
