Sony | Murata 21700 Batteries

Sony | Murata 21700 cells carry one of the most respected legacies in high-drain lithium-ion — the VTC series, now under the Murata name.

Murata acquired Sony's battery business in 2017, taking over the celebrated VTC high-drain line, so these cells combine that proven high-performance reputation with consistent quality. Stepping up from 18650, the 21700 format adds capacity and energy headroom while these cells keep the strong, steady current delivery the VTC name built.

For builders chasing dependable high-output performance with real pedigree behind it, Sony | Murata is a benchmark pick.
