Hand made underwater scooter

[AbyssTek]

Here is a video of tests for a scooter we have built from zero. We will be uploading more videos, and when we have some time, also some parts of the manufacturing process. I hope you like it.

Hello, congratulations, great work.
What type of: motor (P, V.), batteries (V, Ah, autonomy)?
Pressure resistance to what depth?

It is a 500W, 48V motor with a gearbox at 700rpm, powered by a 48V battery made of 65 cells of 18650, 3.7V each, with an approximate capacity of 16Ah, providing around 3 hours of autonomy, and we are still testing it, with a maximum depth reached so far of -35m.We will continue testing and posting here. Thanks for interest

Hi
Thanks
Motor : pure DC with permanent magnet or brushless or other ?
Driver for the motor ? « Hand made » also or ?
Batteries thus : (13 x 3.7 V serie ) 5 x //

Regarding the brushless motor, the motor controller came included with it. This controller is originally from an electric scooter and includes the throttle and other necessary components. Additionally, the battery is equipped with a 20A 13s 48V BMS (Battery Management System).
I believe that when you mentioned the "driver for the motor," you were referring to the motor controller. To facilitate the operation, I have installed a magnetic switch. This switch can be activated externally using a magnet, providing a convenient way to control the system without direct contact.


The BMS.

Yes it's often the general appellation used for motor controller DC, AC, etc
