I have been tasked with putting together an emergency kit for a ranch property. The owner wants LED rechargable lights. Instead of having these things plugged in away from the gear box, I was going to have a smaller box, on top, with a pig tail sticking out, with all the chargers in the box so the box may simply be unplugged and everything taken. If everything is outside, I am then tasked with keeping them clean in a filthy barn.
The short of this is, are there any problems with charging these LED things in a closed box?
