With all the respect this looks more like a tracer charger to me:

I'm afraid that if the redvolts don't work with my chargers I'm gonna have to return them because the all thing for me was having compact and lightweight batteries for location scouting and traveling, and the regular double deck chargers don't fit in a backpack.
I really hope that the support can help me to understand what's not compatible with some chargers on he market.
