I'm noticing that I can only use 2 out of 4 of my REDvolts when I hot swap my bricks. Luckily I label each battery with a number so it's pretty easy to track down which one I can hot swap. But My question is, is this a firmware issue or is this a REDvolt issue? Is anyone else having a similar issue? I would like to be able to do this with all my REDvolts and not have to keep in mind it's only 1 & 4 is hot swappable.
