Sub-C (SC) is a cylindrical battery form factor with 22.5mm diameter and 43mm height, smaller than C size and larger than AA. It is widely used for high-drain power tools and RC models due to its balanced capacity and discharge performance.
Our standard SC NiMH cells support 1C continuous discharge. For high-drain demands, we also provide 5C high-rate SC NiMH cells for power tools and RC off-road vehicles.
Yes. We support custom nickel tab size, spot welding position, shrink tube printing and battery pack assembly. Free technical drawing support is available for bulk OEM orders.
