Does this wire gauge vs amps vs feet look good to everyone?

[OffGridIdaho]

Is it accurate? Nice to have a chart like this if it is...

Would have to verify each point to know for sure.
Too much work for me, but maybe someone will.

I dont know if I could call that the bible either.

I wouldnt be ok with 4 AWG at a length of 19 feet carrying 100 Amperes.

Nor would I be ok with 2/0 at 79 feet at 200 Amperes.
yes Im looking at 10% V drop
Perhaps its me.

Formula
In general, we use the following formula to calculate the thickness of battery cables:

Current (Amp.) x distance x 0.2 = cable mm2 (square-millimeter)

Example 1: a 30Amp battery charger. is at a distance of 3.5 meters from the battery. The formula: 30x3.5x0.2 = 21mm2.
If the result of this formula is not a common diameter, we recommend using the next cable thickness.

Really its easy
Formula is base on 12 volt Cable
30Amps x 3.5meter x0.2volt drop lost= 21mm2
So after that you can do this

30x3.5x0.2 = 21mm2. On 12 vol
30x3.5x0.2 = 21mm2. :2 = 10.6mm2 24 volt
30x3.5x0.2 = 21mm2 :4 =. 5.3 mm2 on 48 volt.

After mm2 you can look awg wat usa use for wire.

A foot is equal to 12 inches, or in other words: a foot is equal to 12 x 2.54 cm = 30.48 cm. If we convert meters to feet, this means that 1 meter is equal to 3.28 feet.

Print it out and hang it up on the wall .
Easy to have it by hand

That is very cool!
Thanks!
