I use these to augment my EcoFlow power stations through the PS's XT60i connection and I charge these from solar panels through a charge controller.

The price is now $260 but the code CD35US gives $35 off but it ends up the same - $225. They seem to mysteriously make back $10, however, with "additional" charges, which are supposedly tax but my tax is 8% and $260 x .08 = $20.06 but the additional charges are $30.36

Tariffs have already been paid, and these are already stateside...the additional charges are likely the cash advance fee from Paypal/others since Ali deals in a cash transaction, not a charge. This was an issue in other threads w/ Ali...use a 1 time use or card with buyer protection when using Ali.

Finally pulled my trigger with 30%CB. Great price if the CB is honored.
I made two separate purchases yesterday for these batteries using the cash back but haven't seen it show up in my account yet. Hopefully it just needa more time.

Heard of "tariffs"? Someone's gotta pay them, you know. I don't think all suppliers just eat them, especially for these slick low profit margin deals.
Then don't lie and list it as a sales tax.

Willing to bet that many Chinese companies are cheating on tariffs.

I have one of these with a 400W solar kit from Eco-Worthy with a 30A controller and a Vevor 2000w inverter. Works perfectly for powering my shed.
What 30a controller did you pair it with?

This is awesome, thanks for confirming it's possible! This was my plan in my head. What cable are you using to achieve this?
