The eco worthy 280ah battery weighs 64lbs. How is this lighter?

The link takes you to the smaller 314Ah version, not the OPs 320AH. It lists as "mini" and I wonder if the weight/Ah is in the different form factor (case size-area to volume ratio). Regardless, it still blows my mind that these are less than half of what they cost just 2 years ago.

FYI - the 320Ah version in op's image is 65 lbs on Ali, but I'm not seeing the same price.

I have a 100Ah that I've mostly used as a trolling motor. Got it with the motor from a friend so not sure what the original cost was. Seems to perform similar to my EcoWorthy or LiTime Mini, no obvious issues anyway. I have not yet connected BT because, apps... and generally charge from a NOCO Genius 10.

The prices across the board are just falling like a rock. I don't want to look at order history and be reminded what I've paid in the past years!
