Toshiba Corporation has unveiled its new SCiB™ 24V battery pack (P25H20-3), a lithium-ion solution designed as a direct replacement for conventional lead-acid batteries. The battery targets automotive, marine, and industrial equipment markets, offering improved efficiency, reduced weight, and environmental benefits.
The battery pack has already been deployed in Yamaha Motor’s electric boat, “e-Float Terrace,” which will start sightseeing cruises in Yokohama’s Minato Mirai district in October. The vessel uses 24 SCiB™ battery packs configured to deliver 48V and 11.52 kWh of power through Yamaha’s HARMO electric propulsion system.
Engineered to meet the D23 size specification under Japanese Industrial Standard JIS D 5301, the SCiB™ 24V pack allows easy replacement of existing 24V lead-acid batteries. Its scalable design supports configurations of up to two units in series and six in parallel, achieving 48V output and 5.76 kWh capacity.
The battery incorporates 20Ah-HP SCiB™ cells, making it suitable for high-load operations such as engine starting. It is ideal for marine vessels, commercial vehicles like buses and trucks, and heavy equipment used in construction and agriculture. The pack also offers waterproofing certified to IPX9K and IPX7 standards, vibration resistance, and low-temperature performance for harsh environments.
SCiB™ technology provides rapid charging, long service life, high input/output power, and a wide usable state-of-charge range, addressing the growing demand for alternatives to lead-acid batteries.
Yamaha adoption of the battery aligns with its efforts to promote sustainable urban tourism and reduce carbon emissions in marine transport. Toshiba plans to expand its SCiB™ portfolio across mobility, industrial, and energy storage applications while pursuing additional orders in marine and industrial sectors.
