Hi I own a lead acid battery restoration company and have been receiving more big business customers lately. To keep up with this demand, I'd like to build a portable tester that can use to test their batteries on site before I transfer them to my workshop. I need the tester to forcefully push 48v through the batteries I want to test so I can pop the caps off and see if any oxygen/hydrogen bubbles are forming and if they are, I'll know the battery's internals are still in tact.
Would it be possible to build a 48v bank of 18650 batteries and then have some sort of isolation circuit that will only transfer the energy one way from the bank to the battery to be tested?
