Hi JohnMat
Thanks again for your reply.
Let us be practical.
It functions and the wires stay cold. And for me that’s not a surprise.
The nice thing is that I crank and the engine starts immediately without hesitation, which it did for sure not before I used a super-capacitor bank.
As answer on your thoughts, but difficult to find the right answer :
Take the capacitor bank as something stand alone.
Yes. The voltage drop is in a short time around 12V, see the calculation here-under.
So I do not understand your assumption of 0.25V drop.
Keep in mind : It is not a battery which do have small Voltage drops, but that's a total different device.
Our Battery has 40Ah and only max 500 cycles to max 50%.
This capacitor bank has max 945As = 0,26Ah is 0,007 times less than our Battery. So our battery can - without extra charge for itself - charge this Capacitor bank more often than his own cycles. And that's why your battery will live much longer too when parallel connected - a hybrid system - to a capacitor-bank..
The capacitor-bank charges faster, It de-charge faster. And will do that also faster than a Battery when not in use.
You can - and you will do - de-charge it 100.000 of times from 15V to zero and back.
And for cranking we only need power for a couple of seconds and after that a device which is charged very fast to 15V to do the same trick again and that's a capacitor
Some formula’s for a capacitor
C(Coulomb) = I ( current in Amp ) x delta Time (seconds )
Coulomb = Capacity ( Farad ) x Voltage
I x Delta T = Capacitance x Voltage = 63 F x 15 V = 945 As
63F is the total Capacity of the bank.
15V is the max Voltage for the balancing circuits.
So with a cranking amp of 350 you are finished in a couple of seconds. So yes - in my humble opinion - a drop of 0.25V will only give you a ‘quantity of charge transfer’ ( = Coulomb ) of 15As and that is a value where we are not talking about.
But the only interesting value for us and our small 40Ah CA 350 cranking battery is that it works - with my cable choice - for me and for mr. Tesla who bought Maxwell recently for his future cars. Sometimes he does - I know unbelievable - wise things too.
I searched for you on Youtube and you can find more examples.
Also it is impossible to solder thicker wires on the contact-points of these Capacitors of 450F.
You have to go to 3000F to get real terminals with bolts.
