"Nice Gear" (is what the FedEx diver said)
I have the Yeti Tank now hooked up to the Yeti 1000X power station, and the wall charger, and all's good. I bought the system for power backup at home, and for possibly road trips in my van. The only thing I might mention so far that needs improvement would be that the very heavy AGM tank battery should probably be shipped with an even sturdier box because mine arrived with the outer box totaly blown out at one of the handles and even the inner box took quite a beating (but the innermost packaging saved the battery). The carries must hate heavy items because mine always arrives beat up real bad. A great product, I like everything that I got from Goal Zero.

Tanks need adaptor to plug in more solar panels
Bought this 1 battery bank to help extend my power needs. So far I can only use 1 of my 3 solar panels to charge the battery bank(you can only plug in the 8mm cord from solar panel). At this point, I’ve realized how everything works electrically, and I’m kind of disappointed with the wiring. The power station will be completely charged(via 2 remaining solar panels), but the battery bank meter only displays 1 green light. It appears if the power station is fully charged, then the extra battery bank doesn’t continue charging to top itself off. After purchase I realized that I have to buy more adaptors just so I can plug in more solar panels…to charge the battery banks in a reasonable time. Other than that, so far I do like having extra run times with the power station. Knowing me, I’ll probably buy the adaptor so I can connect more solar panels together. I’m considering 2-3 more batteries, and then after that I’m done buying everything solar lol. This stuff is expensive and nothing runs as good, or as long as coal power.

Didn't work for me....after 2 tries
Bought the expansion module and back-up battery for my van. Worked for 1 or 2 cycles, then stopped. Worked with Goal Zero and tried everything....shipped everything back and they replaced both my Lithium 1000, the expansion module and the back-up battery. Put everything back together and back in the van, worked for another cycle and then died again.....now a 80 lb door stop. The Lithium 1000 is still going strong, but the back-up experiment never panned out.

What is the minimum operating temperature for the 1.2kWhr AGM batteries? I am putting together a solar/battery system for an off grid yurt in the Colorado mountains where it gets quite cold. Thanks

If you add one of the expansion tanks to a Yeti 1000x how much additional time will the Yeti 1000x last?

Can this item be used with the Yeti 1250? or is there a older Tank version for the older yeti non-lithium units?

Are you able to charge the batteries with solar panels or need to plug into wall only? Would like to be able to use the power station while charging the batteries or consistent power

Do I have to use a HIK with a yeti to be able to charge a Expansion battery, or can I still use the Shore power plug/solar of a yeti 3000x to charge it. I ask because I plan on using it to travel the country.

Will there be a lithium version of this product in the future? If not, can the battery inside be replaced?
