Well, my long winded "quick reply" took me to an error page, and was lost. So here is a brief message, as I have had this problem twice now using "quick reply" option here.
This bag looks fine for use with a separate "hobby" style charger. Using the ones most of us likely have could create unwanted "heat" if the charger itself were put inside the bag, not just the battery by itself, which is how hobby chargers are usually setup, wires running from an external charger to a few batteries. Most may remember the old saying, "heat is the enemy of electronics". Decreasing the battery life itself, and possibly worse. Lucky for me, I have a clean, unused fireplace to put my chargers, outside would be an even better option if you have to leave unattended, as some of the larger mAh batteries can take many hours to charge, tough to baby sit. Mostly common sense, though often not that "common".
Quick and easy!
