They finally came down to a reasonable price. They were $177 on Temu back in January, bought a few back then.

That's my reference point. I got one at the Temu price. Actually I paid lower than $177 using a bundle coupon. I need one more but not until $177 or less.

Generic LiFePO4 prices are dropping like a brick, but the pricing on expansion batteries of any brand have always been insane. Could go either way.What does interest me is whether these batteries will be forward compatible when they release the next River generation like the Delta batteries. If they're not forward compatible I assume there'd be a fire sale at some point to clear them out.
