What is this product?
This product is the KNS 400Wh/kg 6S 22.2V 44000mAh semi-solid Li-ion battery – a highenergydensity rechargeable battery designed specifically for professional drones and UAVs.
It combines semisolid electrolyte technology with a large 44Ah capacity and a standard 6S (22.2V) configuration, delivering 400Wh/kg, which is roughly double the energy density of conventional LiPo batteries. This allows drones to fly much longer on a single charge without increasing battery weight.
