I need to connecto my PCB to the battery while there is a second connector on top which is towards the load.
I was searching for a ring connector, but I can not find one that is 19mm for a battery 12V. Can anyone give a good link please? I am tired of searching!

 

Google "battery terminal"
I have no idea where you are located so I cannot provide a link as it may just be useless to you..

Here in the US you can run to any autoparts or hardware store and easily pick one up for a few dollars..

 

Thank you all for your help in all threads!
