The choice of a storage technology—lead-acid, lithium-ion, LFP, NiCd, or emerging technologies—directly influences the performance, total cost of ownership, and sustainability of a mini-grid. The study shows that climatic conditions (temperature), depth of discharge, sizing, and the BMS play a major role in system lifespan. Utilities and developers must contend with significant technical, economic, and logistical constraints to design systems adapted to their specific context.
