I'm kinda window shopping for when my kid sister wants to build something.... I started looking at https://yixiangpower.com and their MB56 battery is 32kwh for $3500 with JKBMS. Then I popped over to docanenergy and they have a "panda" 48kwh battery for $3900 with some other BMS. The thing that worries me about the panda is that I think it puts several banks of LFPs in parallel and I'm really not a fan of that. The yixiang battery is a straight 16s 1p battery. As for my sis, she has an electric ford truck and we recently got a supercharger station about 5 miles from here. I'm confident enough with home assistant's forecasting solar production that I could begin charging her truck at midnight (give or take the SoC of the house battery and the expected production) so that either her truck would be full by the time she leaves the house or she'd have a SMS message from home assistant telling her she needed to supercharge on the way out. That would only be a few days in the winter. 3 of those 48kwh "panda" batteries would be almost 145kwh. In practical terms, the truck has a 135kwh battery and could be used in a pinch to charge the house. Right now the plan is for her to build on the backside of this property and never connect to the utility grid. We also have a 12kw pad mounted LP generator that can be thrown in the mix for her as well. I just never thought I'd see the day when youd have 145kwh in three batteries for under $12,000usd. https://www.docanpower.com/usa-stock/solar-home-battery/panda-52v-942ah-48kwh-prebuilt-pack-1-1
