MySol 3.5k is a modular backup battery tailored for Africa’s energy needs. Designed for Manufacturing in Africa, it utilises 100% repurposed lithium cells, offering affordability and reducing electronic waste. Resource efficiency is heightened by second-life battery-management systems from older devices, improving sustainability. The compression-based electrical contact ensures easy repairability, extending its lifespan. The enclosure is extruded from recycled ABS plastic sourced from old devices, further underlining the commitment to a greener future.
