>prismatic cells if you're gonna /diy/. Buy cheap chink pre-made batteries
Reasonably trusted prismatic cells are expensive and the cheap batteries often have high resistance used cells

I've built 3 batteries of 96x 32650 cells each 3 years ago and they're holding up well, they're easy to put togheter using plastic holders and metal strips to make parallel and BMS connections, materials cost half of a comparable ready made battery and all the cells from the supplier I bought were good.
