These have gotten so cheap that the payback cost for small solar is now months. Crazy.

I am slowly getting more panels as I have a 180w and a 200w but charging it takes forever still. Need to have 600w going into the battery to maybe charge it in a day lol

But yeah, its been like three weeks since that deal and I've used the battery 3 times already. Don't waste money unless you are a hoarder

I have this coupon too and was waiting for the extra dollar off lol , but still waiting. Luckily don't need the battery but tempted. 280ah is really heavy! 150Ah or 200Ah is more like it

I am definitely a hoarder. 😂. I didn't realize how big the 280ah was. But my main goal with these is to try and extend the run time of my apc upses at home.... I just need to get around to it.

It wouldn't be good to pair this with the 280ah

Especially when power companies charge >50c/KWh. I just kissed them good bye and good luck because once I go off the grid, I ain't go back.
