AWG max current

To transport the current from the battery to the controller
What thickness of the cable do I best use
The charts about it
awg max Amp give me an indication


You have power transmission awg 10 is 15Amp, multiple cables.
use by Chassis wiring awg10 is 55 Amp one cable better cooling
For bike use, cooling by wind
The resistance is lower with thicker cable and so less heat
Is it only heat problem?
Can I use 12Awg for 50/60 Amp or better 10 awg?

If you’re planning to have 50 amps continuous, you shouldn’t really use 12AWG wiring even with chassis wiring. According to the chart 45 amps is the max continuous current for 12AWG even with chassis air cooling, so go with at least 10AWG.12AWG could work if you monitor the temperature but unless you really need the wires to take up less space go with 10AWG.
You are correct in that a thicker cable will have a marginally lower resistance and produce less heat. Heat is the main factor in how much current a conductor can handle, although it’s a little more complicated when figuring out how much of a burst current you can handle (like drawing a hundred amps when first turning on the motor). Too much current and the insulation will melt, and in extreme cases the copper wires will melt and split.

how long is the run?
you can double 12 awg wires and call it
