Great backup plan for random power outages

Ordered to add to my Anker Solix F3800 for more capacity and longer use during a power outage. Recently had a spring blizzard cripple Maine for days, and the backup battery proved priceless as we had no power for 4 days...
Pros
- Plug-n-play
Best Uses
- whole house battery backup for emergencies.

Massive Anker battery
March 8, 2024
This expansion battery by Anker is massive. Product seems to be well made, even though it's on the heavy side at I think 72 lbs. Battery has a great looking with the light the can be turned on or off. The included cable for connection has a neat design that is mostly flexible.
