yes D3 EB works with D2 (not D2Max) but other than size, and the right angle connection cable, D2 EB can generally be had for less $ and physical/style match with D2...

Yes, it's the lowest I've seen too, but it's still way more expensive per watt than a typical LiFePO4 battery. EcoFlow is making us pay 3 times the market rate. One can buy a 48V 50Ah battery for the same money, but it will not charge from the EcoFlow.

It''s not complicated. I'm using a lifepo4 battery, a lifepo4 battery charger, and a m8 to xt60i cable from the battery to the ecoflow solar input. The higher the voltage of the battery, the faster it charges the ecoflow. I'm using a 12V battery, which is good for my needs, but charges the ecoflow at only 200w. I believe a 48V would max out at 500w input. There are a million videos on youtube about all this.
