Yes, thats only, so spread the current equal to all 10 cells.
I could have doubled them too, but its 2mm² Nickel, and each cell has direct path to terminal wires, thats ok.
In the middle the Nickel has to take the current from 2 parallel cells, thats the reason i doubled there
Can’t wait to test them! v_s is so kind to weld them for me! Thanks again it just looks fantastic!
Right I had in head the fuse bus style , so yes double the S where current flows 
Board build
I guess i’ll name it Pink Panther 
Building the Box:
Bandsaw & joining the Parts
Let the Hotwire fun begin:
Shaping with my special shaping tool
Its my first Monoski, i have learned on, still kept IT, no one knows, what it could be good for.
Gives a nice rough shape:
More wirecutting, and a bit of sanding
Laminating, what a awfull mess
Innards ready to reinforce with glass
Final Resin Layer
Some imperfections, but who Cares?
Lucky me, everything fits inside 
I’m really liking the look of this! What is that pink material? I will probably end up building my own board. Any information would be greatfully received. 
Its just usual XPS, used for thermal insulation (house basement)
125 * 60 * 14cm
You can get them in various thickness, i was looking for 16cm thickness, but i would have to order a whole pack, so i only got the 14
The thickest part of the board ist now 9,5cm
150cm long, 55cm wide.
About 55Liter
80100
The APS got only a slight touch up:
Some magnet gap filling, and a coat of epoxy.
Shaft shortend with angelgrinder on a lathe.
Mastclamp
I am happy, that my first print fits Well
Mount 80100 to RL Mast
These files are printable without support:
Very nice design but why a vertical wall only on the right hand side of the front part ? Rigidity ? It stops water going backward 
and supposed to cool the motor down.
The Wall on one side, is to push water into the mast. Its angeled, so i can print without supports.
Small holes in the mast act as sieve
I was thinking that yesterday when doing the air / water test… it’s time to redesign one 
I was about to get the front piece of the rotor out to see that it’s really flush on the inside.
did you measure the power when spinning it in water?
you’re not worried about lack of water circulation?
Get all surfaces as smooooth as possible. Even the stator notches can be filled without thermal worries, just leave a channel open so the wingdings get to water.
Spinning in Air: 162W
Spinning under Water full throttle: 825W
Spinning under Water half throttle: 250W
Test was with 44,4V only. (Battery wasnt charged up)
Stator and Magnets only covered with one coat epoxy. Nothing fancy, just KISS
There is a small gap, about 0,75mm, that should give enough waterflow. At least i hope so
so slight improvement compare to mine underwater… not sure if it’s the fit of the cap or may be some loss between my batteries and motor…
They say “Frischwasserpumpe” so ‘Fresh water pump’:
Yes, selfpriming.
Freshwater… I guess seawater would be no problem. Inside it should be plastik anyway…
I’ve opened one up. It’s all plastic so salt water shouldn’t matter.
