Thanks for the reply. I don’t need anywhere near 1000 A more like a couple hundred but wanted to be able to control it precisely. Typical battery about 900 cranking amps. I was hoping to get several hours from a battery using between 50 and 250 A for different size material.do you realise that 1000A will drain a large automotive battery in about 2 minutes and most would not be able to provide that sort of current in the first place.
however to answer your question, I am fairly sure that you can buy solid state relays to that sort of capacity.
Ageeed. i’m hoping the forum might provide a somewhat detailed explanation and maybe even a drawing of the components necessary to make this work.A large automotive battery is in the region of 100Ah
This means in theory it can provide 100A for 1 hour or 50A for 2 hours , 25A for 4 hours Etc.
For regular change / discharge you should really only use 50 to 60% of the capacity otherwise the battery will fail quickly.
