I’m sorry, Jon, but I’m not an Electrical Engineer, and I did not have various meters hooked up to determine exact voltage and amperage specificity you desire.
A few moths ago I smoked a regulator because I apparently was demanding too high an output (2 locomotives linked together). Going to 3 LiPos with no regulator solved the issue.
Of my 6 dud voltage regulators, I’m uncertain which 3 were smoking. Two began smoking as soon as I applied power (1 LiPo battery) to the terminals. I immediately disconnected them but the damage was done. The third began smoking while I was connecting my voltmeter to measure the output.
Of the one which had been working but died on me, I was using 2 LiPos in series plus a 12-volt regulator. It had been working for a while (several weeks) but then just died on me.
The other two simply did not produce a step-up voltage from the single LiPo battery.
At this point I am just writing the entire matter off as a bad experience. In the future I will try to use 3 LiPos in series which produce sufficient voltage to run my model railroad engines.
I now have a voltmeter (digital, with some decimal places) which my provide some answers. I have been busy with medical appointments lately but hope to investigate the situation soon.
