⚠️ Important Notes on Zooz Batteries
Zooz batteries are generally serviceable, but like most modern packs, they may include smart electronics.
- If a failure is related to the BMS (battery management system) or communication components, repair options may be limited
- If that’s the case, we’ll clearly explain the issue and provide next steps
