Dear Bluetti Development Team,
I own multiple Bluetti units (2x AC500, AC200PL, and PR200V2) and would like to request an important battery longevity feature.
Current Issue:
When I set SOC High to 80%, the system constantly cycles between 80% and 81%, creating unnecessary battery stress through frequent micro-cycles.
Proposed Solution:
Implement user-configurable SOC hysteresis with:
- Upper threshold: User-set value (e.g., 80%) - current high soc
- Lower threshold: User-configurable offset (e.g., 50% or 30% below upper)
- Default behavior: Keep current tight cycling for users who prefer it
- Optional setting: Allow users to enable wider hysteresis bands
Benefits:
- Significantly reduces battery cycling stress
- Extends overall battery lifespan
- Maintains system functionality while improving longevity
- Gives users control over their battery management strategy
- This feature would be valuable across your product line, especially for users with permanent installations or frequent use scenarios.
Thank you for considering this enhancement.
Best regards,
Przemek
