1024Wh?
First, this battery is not 1024Wh as put in the title. Second, it offers nothing special but a $50 higher price and no extra warranty compared to the current sales all over internet. Last but not the least, you need to buy the newest battery adapter that cost several hundreds of dollars just to connect 2 of these batteries to a power station. It makes no sense to spend almost $900/extra battery and spend around $300 for the adapter because the battery outlets have been reduced from 2 on Delta 2 series to 1 on Delta 3 series to sell an additional extra adapter. Bad business!
