Sony | Murata 21700 Batteries

Sony | Murata 21700 batteries are premium high-drain lithium-ion cells with one of the most respected legacies in the cylindrical cell market.

Sony's battery division — maker of the renowned VTC high-drain series — was acquired by Murata in 2017, and these cells now carry the Murata name while continuing that high-performance lineage. The result is a brand that pairs a proven reputation with consistent, high-quality cells. Its 21700 line is built for strong, reliable current delivery in demanding builds, in the larger format that brings more capacity and energy headroom than the 18650.

For high-output builds where pedigree and consistency matter, Sony | Murata remains a benchmark high-drain name.
