An external power source can be a better choice for an underwater ROV because it can provide several benefits over an internal power source. Here are some reasons why an external power source can be a better choice:
Longer Operating Time: An external power source can provide a longer operating time for the ROV. This is because external power sources typically have a larger capacity than internal batteries, and they can be replaced or recharged quickly without needing to bring the ROV back to the surface.
More Power: External power sources can provide more power to the ROV than internal batteries. This can be important for ROVs that require a lot of power to operate, such as those with multiple thrusters or high-resolution cameras.
Safer Operation: Using an external power source can be safer for the ROV and its operator. If an internal battery malfunctions or leaks, it can cause damage to the ROV and the environment. An external power source can be located outside of the ROV, reducing the risk of damage in case of a malfunction.
Flexibility: With an external power source, it is possible to use different power levels and sources depending on the ROV’s specific needs. This can provide greater flexibility in the operation of the ROV and make it more adaptable to different environments and tasks.
Easier Maintenance: External power sources can be easier to maintain than internal batteries. They can be easily swapped out or replaced, reducing downtime and making maintenance more straightforward.
Overall, an external power source can be a better choice for an underwater ROV because it can provide longer operating times, more power, safer operation, flexibility, and easier maintenance.
