Goal Zero Yeti Link Expansion Module V3, Tank Battery Connector with 120W Power Supply

This module manages the connection between my Yeti 1500X and two Tanks, and the included 120W power supply keeps everything topped off when the grid is up. Setup was literally plug and play. The app shows each battery's status, and charging behavior has been flawless for three months now.

Connected my Tank instantly. No issues at all.

Only compatible with Yeti 1500X and larger, which I knew, but a friend ordered one for his smaller unit and had to return it. For the right station it's seamless. Build quality is typical Goal Zero, which is to say excellent. Big discount made it easy.

It works well but remember this is basically a required accessory if you buy a Tank battery, so budget for it. The 120W supply is a nice inclusion. No complaints about function, just wish it were bundled with the Tank.

The charge management logic here is what sold me. It treats the lead-acid Tanks gently and balances everything with the lithium base unit automatically. I've run a fridge and lights off the combined system through two outages without a hiccup. Worth every penny at the sale price.

Does exactly what it's supposed to do. Integrated my Tank with my 3000X in minutes. Four stars only because the power supply brick is a bit bulky.

I was worried about anything involving batteries and wiring, but this module made expansion completely approachable. Color-coded ports, a clear manual, and the app walks you through the status of everything. My whole backup system for the house came together in an afternoon. Highly recommend for anyone who wants backup power without complexity.
