Charged Armor Set Location
You can find all three pieces of the Charged Armor Set along the Dracozu River in Faron during the main quest Secret of the RIng Ruins.
Charged Shirt
Off to the left of the campfire, you'll see a light coming from inside the ruins at coordinates 0968, -2531, 0008. Go in here to find Tauro, who is investigating the ruins and translating the text.
Although Tauro can't open it, Link can so go straight up to the Treasure Chest and get yourself a Charged Shirt.
Charged Trousers
Follow the river south, taking note of the Dragon mouths on the pillars along the way. You'll come to a point where there are Lizalfos in the water. Keep an eye on the right side of the river just beyond them, to see another light glowing from the ruins.
This one can be found at coordinates 0980, -2693, 0007 and has an entrance blocked by rocks.
Destroy the rocks with your hammer or something like a Bomb Flower to gain access, and at the top of the room, there will be another Treasure Chest, which contains the Charged Trousers.
Charged Headdress
Exit the ruins and continue south along the river. As the river starts to bend, you'll see some Lizalfos positioned just above, on a bridge and wooden ledge sticking out from the rock.
One of them will fire electric arrows at you, so watch them closely. Take them out to grant yourself safe passage and break the boxes on the ledge to get Roasted Bass and Arrows.
Continue down the river, and shortly after them, you'll see an Electric ChuChu on the right. Opposite this, on the left side of the river, another light glows from the flooded ruins at coordinates 0968, -2800, 0007.
You can just slash the roots that block the door here, and find the chest as you have with the other two, at the back of the room.
Charged Armor Upgrade Materials
After you find and unlock the Great Fairy Fountains in Hyrule, you can bring them ingredients and a donation of rupees to increase the armor value of each piece of armor. All pieces of the Charged Armor Set will require the same materials to upgrade each. See the table below for the ingredients needed and defense bonus you can gain for each piece of armor.
The Set Upgrade Bonus for the Charged Armor Set is Stormy Weather Charge. This allows you to charge your attacks faster during stormy weather and adds an electric effect to charged attacks and combo finishers.
