The image isn't working for me, but what I can tell you is that a BatBox can only take 32 EU/t. It might be able to handle more without exploding, but it'll fill up and waste power once it's full, so there really is no reason why you would want to give it more than 32 EU/t.
If you want to convert more than 32 EU/t to 32 EU/t you should use a transformer(s). From an MFSU (which outputs 512 EU/t I think) you should first transform down to 128 EU/t (MFE level) and then down to 32 EU/t. If you type in "transformer" on the IC2 wiki or NEI I think you might be able to find what you need.
I'm no expert in IC2 power though, so I might be missing some information, but I think this should point you in the right direction at least.
