Toshiba has introduced a new SCiB 24V battery pack (P25H20-3), a lithium-ion solution developed for automotive, marine, and heavy equipment sectors.
The product is equipped with 20Ah-HP SCiB cells, and has been designed to meet the D23 size specified by the Japanese Industrial Standard for starter lead-acid batteries (JIS D 5301).
The SCiB 24V battery pack can be deployed as a standalone unit or configured in series and parallel — up to two in series and six in parallel – providing power up to 48V, 5.76kWh) and has the capability to handle high-load operations, such as engine starting.
“We engineer SCiB batteries for outstanding reliability in demanding environments,” said Toshihiko Takaoka, vice president, Battery Division of Toshiba Corporation.
Low-temperature performance
“The 24V battery pack combines excellent low-temperature performance and vibration resistance with robust waterproofing certified to the IPX9K and IPX7 standards.
“Its exceptional long-life performance helps reduce maintenance requirements for electric boats. To extend these advantages to more partners, we will continue to pursue further orders across marine and other applications.”
The battery pack has already been adopted by Yamaha Motor in its e-Float Terrace electric boat designed for sightseeing.
The vessel is equipped with Yamaha Motor’s proprietary HARMO electric propulsion system, powered by 24 SCiB 24V battery packs configured as two sets of two in series and six in parallel with a total power of 48V, 11.52kWh.
Cruise experiences on board the e-Float Terrace began in Japan in October 2025.
