While playing around with my battery setup last night, I ran into something unexpected.
Here's my setup.
Powerwerx SS-30DV power supply with 2 power pole connectors on the front.
Radio is plugged into the bottom power pole.
Battery is charging off of the top power pole. Charge controller showed that it was receiving power from the power supply as well as the radio was functioning fine.
Well, I was done for the session and I turned off the power supply.
To my surprise, the radio remained on. It took me a second to realize that the battery was backfeeding the power supply and the radio was running off the battery. Completely unintended on my part. I just assumed that once the power supply was turned off, it wouldn't pass power. But then I thought about it. The power poles are obviously on the secondary side of the power supply and so are isolated from the switch.
So a couple questions.
1. I didn't even think about it, but I assume it is best practice to remove the battery connection from its charging source once the charge is complete. Am I correct here or does it really matter?
2. Am I hurting the power supply by backfeeding it from the battery?
3. Are you surprised that the two power pole connectors on the power supply are connected?
Thanks
