I bought a 1 to 10 amp charger for my Wolf King GT to charge faster, to make a long story short, each charging port has a 6.3 amp 5mm x 20 mm slow blow fuse. I blew one of the fuses. Changing the fuses is not easy since you have to remove the battery because everything is packed in so tightly. I bought parts to split the current evenly between the two charging ports with a 5 amp fuse on each side so that this does not happen again. If anyone is interested, I can post a picture once I have it built. Let me know what you think
