Eleaf Mini Pico with Velocity RDA Resistance Question

I recently purchased the Eleaf Mini Pico. I wasn’t particularly happy with the RDA that came included with it, primarily because the air flow slots are located at the bottom. When I squonk the box, juice consistently leaks out of these air flow slots. I found myself with juice everywhere, all the time, even when only squeezing the bottle 3-4 times.

To remedy this, I went out and purchased a Velocity RDA. It fits and works great on my Reuleaux, but I’ve encountered an issue: a .19 build on the Velocity RDA simply won’t fire on my Pico. It performs perfectly on my Reuleaux, but not the Pico.

My current hypothesis, given that the Pico only uses a single 18650 battery, is that the build resistance is too low for it to handle. I’m quite new to dripping, so I’m wondering if my assumption is correct. Any advice or confirmation would be greatly appreciated!
