I want to share some feedback with my tests with lipo battery :
- First test with 2 multistar 4S 20A, serial configuration, ESC 180A hobbywing
Ride time : 20 minutes max
Amp during session : 60A (Foil out of the water)
the voltage decrease very quickly (after 1 minute) and it’s more difficult to out of the water when you touch.
Temp after 20 minutes : 60°C ( ESC into the box, watercooling close loop)
Temp after 20 minutes : 40°C ( ESC out of the box)

2 X ZIPPY compact 6S 5A, serial configuration, ESC 130A hobbywing => don’t use this lipo very dangerous, burnt after 2 minutes of ride, 80°C into the box
-
2 X Zippy 5S 8A , serial configuration, ESC 130A hobbywing
Ride time : 8 minutes max
Amp during session : 50A (Foil out of the water)
the voltage decrease slowly and it’s easy to manage the power, but unfortunatly this kind of battery doesn’t exist in 20A
Temp after 8 minutes : 50°C ( ESC into the box, watercooling close loop)
Temp after 8 minutes : 45°C ( ESC out of the box)
- 2 X multistar 6S 20A serial configuration, ESC 130A hobbywing
Ride time : test only 25 minutes but there was still 48% power (I think I can ride 35/40 minutes)
Amp during session : 45/50 A (Foil out of the water)
Nice, more difficult to manage the power but you keep the power during the ride
Temp after 25 minutes : 45°C (ESC out of the box)
