Pros
- Tied for the longest cycle-life rating (4,000 cycles to 80%)
Cons
- No bottom-4 finish in any scored metric
Pros and cons are derived mechanically: a metric makes the list when this model finishes in the top or bottom four of the 12 units we track.
Who shouldn't get it: Skip it if you need multi-day whole-home coverage — the 1 kWh class runs the essentials, not everything.
