I have this CMB and wan't it to use it for my wii project. The problem im having that the wii uses 16watts with screen etc. and the CMB can only charge with a maximum of 8.4W, so it wouldn't charge while playing. I was thinking to get an other one to put in parallel which would end up using 4 batteries in 2x 2s configuration. I would use 21700 5000mAh batteries which give me 10000mAh. With the second CMB it would charge in 5H instead of 10h. Are there any problems that could occur or am I safe with using it in this configuration.
