You will notice that the e-foils have a larger range. This is because once flying the e-foils use much less energy compared to a Jetboard which has to compensate the resistance of the water surface.

Some electric surfboard battery comparison explanations:

• BMS stands for battery management and is probably the most important part of an battery. The BMS usually measures many different things, such like temperature, current voltage and many more. Each manufacturer is usually creating its own BMS, so they are all different. It is kind of the secrete sauce.
• IP67 – The IP Code, or Ingress Protection code classifies and rates the degree of protection provided by mechanical casings.
  • The first digit indicates the level of protection that the enclosure provides against access to hazardous parts. For IP 67 the 6 means the battery is certified for ” No ingress of dust; complete protection against contact (dust-tight). A vacuum must be applied. Test duration of up to 8 hours based on airflow.
  • The second digit 7 stands for: “Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 meter (3 ft 3 in) of submersion)”.
• IP 68 – Same as the above, but the 8 stands for “The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects. The test depth and duration is expected to be greater than the requirements for IPx7, and other environmental effects may be added, such as temperature cycling before immersion”.
• Nominal Voltage – The reported or reference voltage of the battery, also sometimes thought of as the “normal” voltage of the battery. Typically the voltage when in use where it drops from the maximum voltage.

Lithium Ion batteries need to be handled with care. For more details refer to our battery safety guidelines.

Other than Jetboards like Lampuga  and eFoils the batteries of E-SUPs such like Sipaboards or Scubajet have much less power, but should nevertheless still follow these guidelines.
