The pack company

Lithium done like a product, not a mystery box.

Cellwatt sells inverter, solar and EV battery packs. Every listing publishes voltage, capacity, chemistry, BMS current and warranty. That is the whole point.

LiFePO4 for homes and solar — stable, long cycle life, safer chemistry for a utility room. NMC where an EV needs energy density. We do not mix those stories.

The shop runs on PHP. Connect MySQL from install.php. Until then orders and products live in JSON files so COD still works.
