Those are all questions I want to find out the answer to. I've been eyeing some prismatic lipofe4 cells on ebay.

A NUC is a small computer, imagine if you look a laptop guts but no screen and tried to put it in the smallest box possible.

Are prismatic lipofe4 cells the same power density as cylindrical cells? I guess they aren't or all the batteries would be rectangular.

Lifetime of lead acid batteries is worse, and they are much less energy dense. But they are less expensive, though the gap is closing. They have LiPoFe4 car battery replacements that are (IIRC) 2-3x a normal battery.

What is affordable?

I ordered 8x 20Ah lifepo4 pouches, so I need to figure out how I'm using them exactly.

I got a free cell somehow, so now I've got 28.8V of lifepo4. The plan is something like this: Bidirectional charger between car and lifepo4 (looking at LTC3871) Eventually add AC charging for the lifepo4, which would let me charge the car battery from AC indirectly 36V supply for audio and inverter is going to be LTC3897, maybe with a system to turn some phases off for better efficiency at low load TAS3251 for amplifiers Cell balancing - not sure, looking at stuff like LTC3300 with active balancing that can move charge between cells and not just cell to pack, might try to clone the 3300 with a little microcontroller Still need to pick a controller and UI stuff. It'd be cool to have an eInk display.

That looks nice, I am a little disappointed it isn't the world's finest cooler. What is 'power pole' charging?
