Would it be possible that you send some pictures of how you connected the balancer Cable to the cells ?
You´ll see it above:
And here:
Nickel strips left one tab a little bit longer (under the blue shrinktube) for the balancer connector.
(in CAD picture from battery pack not drawn)
Hi Marcus, how did you secure the boxes for the batteries? I am using similar boxes for my batteries. I also see you have a 4th grey wire going into one of the boxes, what is this wire for?
The grey wire is for antispark. It‘s battery plus connected to VESC plus with a resistor to limit current for uncharged VESC capacitors.
The battery boxes are secured with hook tape and additional withe a 3D printed part that ist glued at the hatch cover.
Today maidenflight @ sunshine and 5°C watertemperature
Most time for first ride on knees, 20% standing.
Was not easy, board is very „zappelig“ in german.
Will try some other setups
What app is that you are using for logging?
By the 32 N Have you put anything between your 3d Print and the fluid? So the 32 N doesn’t stick to ist?
Directly poured in the 3D mold without any release agent. The Wagnersil silicone is sticking to nothing (maybe only to itself?)
After short time of reaction time (~20 minutes) very easy to peel out of the form without any sticking.
It‘s also possible to mold with undercuts because of the soft Wagnersil.
I love this blue fluid
Bad wheather in Germany
Time to build second battery pack. Again 2x 7S8P to have 14S8P with Molicell P42.
The first same pack with ~1.6kWh gave me on my first 7 rides now a operating time of ~1 hour and something over 17km range.
From where do you order ist I also live in Germany?
Oh sorry i Mean the 21700 Molicell P42
And did you 3d Printet the Holder fpr the Cells by your selve?
Nkon in NL, but they are now sold out
yes, see CAD picture somewhere above
Little update after 4 month of foiling, 2 month of it excessiv 3-4 times a week at the end with trying to jump.
The acrylic frame under the gasket broke at several locations and I had some water inside the box. Not critical because all electronic components are inside at least IP67 boxes, but not nice.
I decided to replace by an frame out of 3mm aluminium, 2mm would have been also ok. Again sealed/glued with Dekalin.
Let‘s see how good it will work. For now it is 100% tight again
It was a great season (still foiling) with estimated more than 3000km on the water
One highlight was one week with 24/7 foiling on the Eastsee in Boltenhagen in September 2023
For 2024 I want a new board: Smaller, less weight, faster opening/closing of hatch, longer Gong V2 mast with more stiffness.
Build of V2 has started now… see new post
