The automotive-grade cells used in this model are designed to withstand 3000 cycles at 80% depth of discharge under heavy electric vehicle use.
For instance, cycling the battery daily—bringing it down to 20% state of charge and fully recharging it—would take approximately 8.2 years to complete 3000 cycles before the battery is regarded as end of life, degrading to 80% of its original capacity while remaining operational for some time thereafter.
In less demanding applications such as caravan storage, you can expect longer cycle life.
