LiFePO₄ vs NMC (camping buyers)

High-level chemistry tradeoffs. Always defer to the specific product’s published cycle-life and safety docs.

	LiFePO₄ (LFP)	NMC (typical)
Cycle life claims	Often higher (3000+ advertised on many LFP stations)	Often lower cycle ratings
Weight / volume	Heavier for same Wh	Often lighter / denser
Camping take	Great for frequent van/home use	Fine for occasional weekends if Wh fits

Usable DoD planning in WattNeeds defaults (0.90) fits either chemistry as a planning factor — manufacturers still define true usable Wh.

Wh calculator — nameplate = (Wh/day × days × 1.15) / (0.90 × 0.90).
