Guys,
What do you think should be the minimum bus bar thickness for 24V- 7s80p system?

Its more like 3,5A/mm2 for Al and 5A/mm2 for Cu.For Aluminium : 0.7 Amps / 1 Sq.mm of Bar.
For Copper : 1.2 Amps / 1 Sq.mm of Copper.
later floyd
I have been told this calculater is conservative
Yes agreed, I did say it was conservative should have said very conservative.Would really be tragic is a 50mm2 Cu conductor can only carry 60A
I'm hoping this is a typo. Did you mean 7s instead?? Because 7p would mean each cell is having to output 14A to meet the 100A peak.I think I will assume max 100 Amp for the whole battery -7p
Not really - a given wire size can handle xxx amps for yyy temp rise & this doesn't really change with length.The shorter the wire, the more current it can handle before heating up. This is because there's less resistance in the wire.
I tried that calculator & I think it has a bug or two!According to this calculator: https://www.omnicalculator.com/physics/dc-wire-size
The longer the wire, the more the resistance. This is why length matters. All wire-size/amp charts include length as a measurement.Not really - a given wire size can handle xxx amps for yyy temp rise & this doesn't really change with length.
Yes that's true but it doesn't change the current carrying capacity rating.The longer the wire, the more the resistance. This is why length matters. All wire-size/amp charts include length as a measurement.
