One of those? listed on ebay for like $1100. If you have 2 months to wait your can buy 2x that for the same price in a DIY LFP battery from the group buy here on the forums
 
That's the guy that puts hundreds of listings on eBay for the same item. Makes it nearly impossible to shop for any other products. I won't buy those batteries just on principle

When you work out the numbers, DIY can save a pile of loot ! You also gain the knowledge of how it's all put together and how it should work as you study up a bit. It is NOT for everyone because it can become detailed with a high learning curve, requiring extensive Patience.

There are Known Good preassembled batteries which are available that are discussed on the forum.
Tale your time, do research here for KNOWN GOOD vendors, suppliers & products and Most Importantly, DO NOT Impulse Buy ANYTHING !

Hope it helps, Good Luck
