All LiFePO4 batteries come from China – including ours. But we don’t buy just anywhere; we buy directly from one of the three best manufacturers with whom we have a long-term partnership. We inspect every delivery, handle customs, shipping, and quality assurance – so you don’t experience any nasty surprises. You get tested quality without any detours – and we receive a fair, honest share in return. Nothing more, nothing less. We believe in a new kind of economy: honest, clear, and on an equal footing with people who want to take responsibility. Batteriewunder stands for more than technology. We stand for self-determination, for simplicity, for reconnecting with what really matters. If you feel it’s time to shape your life consciously – then you’ve come to the right place.
