LI-ION battery to power the scooter

Lithium ion batteries are the most powerful rechargeable batteries currently available for electronic user products. The battery technology used in Yamaha's Li-series underwater scooters is the same as that used in today's electric vehicles and delivers excellent performance, efficiency and endurance. Li-ion battery powered devices provide a high power-to-weight ratio compared to devices operating with Lead-Acid (lead acid) or Ni-MH batteries. They therefore have the particular advantage of being lighter and more powerful than other types of rechargeable batteries of the same size. Li-ion batteries are not a problem for air transport. 

Another advantage of Li-ion batteries is that they do not have a memory effect (so there is no need to fully discharge them before recharging), a significant amount of charge remains in the battery even after a long period of time without charging (e.g. during storage) and they can handle many (hundreds) of charge and discharge cycles.

The Li-ion battery system of YAMAHA underwater scooters is compact and lightweight. The batteries can be easily removed for external charging or for battery replacement. Li-ion batteries are a greener option to other types of batteries and have twice the life of conventional batteries. Charging time is also significantly reduced with these batteries.
