Small-sized batteries are gaining popularity, and I'm currently considering purchasing a LiFePO4 battery. I'm drawn to the compact form factor, but I've noticed that many of these smaller batteries use pouch cells instead of prismatic cells. I'm aware that some EV manufacturers use prismatic cells while others prefer pouch cells, possibly for cost considerations but both seem good. I'm wondering if pouch cells are a reliable choice, or if prismatic cells are significantly better. Is it safe in the long run to invest in a small-sized battery with pouch cells, or should I lean towards considering the prismatic?
