Battery drain from DC-DC Converter?

[imorton]

Good day everyone, I have just purchased this DC-DC Converter, and I am wondering if I wire it on the battery output, if there will be a drain on the battery should I not use it…?

In other words, I am contemplating wiring the DC DC Converter "in between the battery & controller", but am worried that it will drain the battery when not in use?

Anyone have any experience with the converters.

I want to put a cigarette lighter plug on the converter output, so I could use a small electric air pump, or charge my phone, etc….

Thanks for any ideas or help, IAN.

Update: I know I could somehow find an appropriately sized switch and install it, but I was hoping that there would be no battery drain when it is not in use…?

The ones that I use do have some battery drain. I always unplug my battery at the end of a ride.

It's unlikely that any DC-DC you find will have zero power usage whenever it is hooked up to a power source. It might be minimal, but it'll still be using some.


However, since you probably want to turn the devices attached to it on or off anyway, why not put the switch that powers them on the battery side of the DC-DC instead? (assuming that they don't have switches built into the device(s)

I've got mine connected through a solid state relay, which is switched by an unused 5V source on my controller - in my case, this is the throttle. (My controller draws very little current on standby, so I typically leave it plugged in.) The DC-DC converter becomes energized when I turn on the controller, with a power button on the display...This is how I power my lights.

Hmmm, some very good points here…

Maybe I could do add an external switch, or figure out how to place it after the "scooter's on/off switch"…


Decisions, decisions,….
