Some more to add about the DC/DC equalizer system testing.
These samples I have sealed them up and mounted in the battery box. Tested well for a while but then they stopped working. I put the multi meter in the output wire to see how much current, if any, was flowing.
They worked well, too well, more amps then they are supposed to put out. The pic below shows 4.66 amps. I had seen as high as 5.8 amps, at one stage. But then, take the multi meter out of the circuit output wire and they did not charge.
It was found that they only worked with a small resistance. So I calculated the resistance provided by the multi meter - 0.047 ohm or so. The smallest resistance I could find was 0.1 ohm. It worked, but cut the current back too far, back to 2.4 amps. I have requested that the manufacturer add a small resister to the output of the circuits.
This is charging the low volt cells from the higher volt cells.(far better than the 0.6-0.8 amps that some burn off systems have from other manufacturers).
