Here is the complete document, where it is described why one side is making a getter connection. Also a lot of other interesting things there to read. This link was already posted a few posts above...

A few posts above yours you can find good explanations aboit kcap and sandwich method.

Thanks for the answers :thumb:

@tatus (Frank): For me it would be interesting to know the differences between the old kCap-board (Maxwell) and the new one (SkelCap). From the posts here it looks like that you can't overcharge the new board, because the charging automatically stops and so there is also no need for increasing...

Charged until the kCap shows that it is full, so more than 8.2V. I didn't remeber the correct voltage, this happened months ago. But this little higher voltage alone can't explain the rise of the current for 50% more.

In the future I will maybe get bigger cables to reduce the resistance to get even more current, but for now it is enough for me.

Here is the datasheet. Much lower ESR and therefore much higher short circuit current.

The new version of mine uses SkelCap 0300 with a rated voltage of 2.85V, so 0.15V above the old ones.

9.5V is also OK on my side.

As already said in the past, 8.2V is too low to get the Caps completely full, if it is a newer kCap with different capacitors on it.

On my kCap with the SkelCaps I need tu use more than 8,1V, otherwise the indication LED's on the PCB of the kCap would indicate that it is not fully charged. I increased the input voltage to around 9-10V and that is fine. As written a few posts before, it looks like that the new SkelCaps can...

Hello The newer kCap have different caps and need a higher input voltage. Increase the voltage and the kcap will function. I have written something about the new kcap a few posts before. I think on my kcap I have increased the voltage to around 9 to 10V.

Has anybody made a kind of base plate to connect the kCap and the kWeld physically, so that it is one part?

The length has nothing to do with the diameter. The length is still the same when you upgrade your cables to AWG6. This is because of the inductive kickback.
