Great value for storage
1,200 watt hours for under a hundred bucks is unbeatable. It's heavy — it's lead acid, after all — but it sits in the garage doing its job quietly. My Yeti runtime nearly doubled.

Heavy but worth it
This thing is a brick, no way around that, but the capacity per dollar is fantastic. Paired with the Link module it integrates seamlessly.

Good expansion battery
Adds serious capacity. Just remember it's lead acid, so it's heavy and doesn't like being fully drained. Keep it topped up and it's happy.

Perfect for my setup
I'm a retiree on a fixed budget and outages worry me. This plus my Yeti covers the essentials all night. Simple, heavy, dependable — like things used to be made.

Works, heavy caveat
Does what it says. But at 84 lbs it's a two-person move, and lead acid needs maintenance attention. Fine as a stationary unit.

Massive capacity boost
Exactly what my home backup system needed. Charges fine from the Yeti and holds its charge well between outages.

Arrived with a dead cell
Mine showed a bad cell right out of the box and wouldn't hold voltage. Return process was smooth and the replacement works fine, but quality control on these needs work.
