I'm planning to get a 10.8 battery for my KWA in the next day or so and i'm wondering if i should get a new fuse as well? I'm using the stock fuse now and i've seen people use li-po batteries on KWA's right out of the box so i'm not sure exactly what i should do. If i should get one which kind would i need and is it something i can pick up at like Radioshack?
