Why Hardware Startups Are Choosing Modular Batteries

Hardware startups face a brutal trade-off: ship a product fast, or lock in a battery architecture you'll regret for years. In this episode, Lucas and Luna dig into the rise of modular battery systems — why a growing number of device makers are swapping glued-in packs for swappable, standardized cells. They walk through the economics using a real-world example: a hypothetical e-bike startup that cut its replacement cost from $300 to $80 by designing around off-the-shelf 18650 cells. They compare modular designs against integrated packs for energy density, thermal management, and…
