When constructing a DIY battery pack using **lithium-ion cells**, such as 18650 and 21700, safety should be your top priority. These cells are known for their **high energy density** and efficiency, but they also pose significant risks if not handled correctly.
This guide includes visual mapping of how these codes and standards interrelate, highlights major updates in the 2026 edition of NFPA 855, and identifies where overlapping compliance obligations may arise.
Considering the low cost of this system (typically 500-800 euros without the subsidy, check prices here), it's generally worth applying, since you can cover almost the whole price of the system with the 500 EUR.
