I was just wondering because I just had this idea
I know this might be a bad question but would multiple drill motors be powerful enough to move a jetsurf
« Multiple » has how many you think ?
18v so 5cells , 4ah probably 2 cells : so worth about 25€ of 18650 instead of 75€
For e-surfing looking at least with these : 36v 40A if they are able to take the discharge ( with their bms ) 20 of them : 1500€ With some space and weight
Now taking Samsung 40t cells you can do the same for less than 500€ , 8kg ( twice less) …
