Try to use low resistance wire. Anyway I don't think 5 meters of wire can steal you too much power.
Now that I think of it, I did start this thread in "general" section. Maybe I should have done it in "suspension" section.

Lets say the car weights 1000 kg. (I think it's 1070 actually but 1000 will do a good aproximation)
Front suspension suports 650 kg (65%)
Rear susp. 350 kg (35%)
You get rid of 20kg front a little fordward than front suspension what would do more than 2% but I'm just getting an aprox.
You put it just in the same line than rear suspension, so you add a 2% of total weight back.
This does a final weight distribution of 63/37 if (let me repeat) im not mistaken.
I would say the biggest error should be at the front aproximation because battery is further than the suspension front struts.
their is something you missed in your theory... the correct calculations should be done based on the car's center of gravity not its geometrical center.
in opther words assuming the center of gravity so based on this the force that the battry apply on the body is its weight x the distance to the cg... when you move it to the back then you shifted the same 20kg to the other side of the cg but now you are way too far from it so you are practically applying more force... try to think of it as a simple lever theory.
i got the battry in the engine bay but got 35 kgms worth of tools in the back... i guess it nmakes it a bit more balaced than stock lanoses... and a bit heavier as well.
As I said it was an aproximated calculation. I used weight over suspensions. I'm sure the weight movement is more towards the rear, as I took away only 20 kgs from the front. As I said, batery is further from the center of gravity than the front suspension, so it should be higher.
Anyways I think it can't be much more than 62/38. It's just 20kg, We are not talking about moving the entire transmission. Or the engine mount.
Remember it was an aproximated calculation. I took a total weight of 1000 kg wich is not the real number.
