DIY Accubox 12V LiFePo4 50Ah for Bluedrive Power Fin

The standard cruising time in the canoe with Power Fin and the included 8.8 Ah battery pack is 1 hour at a cruising speed of 4 km/h. This can be increased fivefold by assembling the battery box below. A pre-assembled battery box for this purpose is impossible to find in Europe, which is why I started this self-assembly project using better components such as LiFePO4 cells, BMS controller, switches, etc., with a DIY manufacturing cost of approx. €300 incl. VAT (excl. 10A LiFePO4 charger). 
The battery box for this purpose must be waterproof (IP67). In the future, I would like to be able to connect a 200W foldable monocrystalline Solar panel with a Victron SmartSolar MPPT 75/15 for charging.
