Wintering and battery

I bought my R8 last month and drove it into the garage after a nanosealing for “wintering” because I can only drive with session license plate from April. I stuck off the positive pole of the battery. But I’d rather if I could take the whole battery out to store it in the warm apartment and charge it every six weeks. Now to my question: Can someone tell me what I have to dismantle everything to get the battery out? At first It looks like I have to unscrew the complete covers at the front. Is this a big act and you get everything back without any problems? In advance, thank you very much for your help and greeting from Kaiserslautern. 🙂
