Good morning.
After completing the tow boogie I’m getting the idea to make a foil assist. There’s a few other guys in the area who also like the idea so may well build a few in parallel.
Had a good read and a search and put together a list of useful parts and links.
I have a Bambu 3d printer and am a capable battery builder. (Have considered that the other guys may prefer lipos)
Thinking 12s as I have a load of bms’s and chargers from skateboarding days.
Nothing set in stone but from what I can see these seem like popular choices.
Anyone sees any blatant dreadful choices let me know.
Have been looking for IP68 cases but seem to be thin on the ground.
Probably very little difference.
Could be that Camdenboss under rate their equipment?
Ip67 is supposedly accidental short term shallow immersion where ip68 is supposed to be deeper continuous?
It is my understanding that the IP rating is an industrial standard NOT a license so each manufacturer uses independent testing labs to see if their product meets a particular level and then is trusted to stay compliant.
In today’s world that’s pretty “squishy” as a manufacturer could simply claim their product is IPXX compliant and who’s to know better or perhaps alter their build process and not retest at the lab.
If you are buying product from a known reputable company I think it’s safe to believe that the 8 level product is more “waterproof” than the level 7 or perhaps they only have one version and sell it as a 7 at a discount to drive volume.
If you look at the performance/longevity of the Flipsky VX3 IP67 vs their VX5 IP68 it would seem the rating is accurate.
IP68 from Peli I think should be a pretty good.
As well as being ip68 and a nice form factor I think this is going to be pretty nice fitting.
12s3p battery with Bluetooth bms, in theory leaves space for a chunky esc, cabling and transmitter.
A 12s4p does fit. (Pretty sure I have an old photo somewhere)
You could probably stick a waterproof esc on the outside if it didn’t squeeze in?
I was thinking a swappable 12s3p might be optimal for weight?
12s4p vs 12s3p is gonna be less than 1kg weight penalty… Lets say 1% of my body weight… won’t make much of a difference… Yet greater time on the water…
If you check the peli website they have dims and 3d models for all their cases so you can model something up. (You probably know that)
Because of the way I’m choosing to build the pack I’ve wasted quite a bit of space.
On that note, the “weapon case eFoil” I have uses a Nuprol X-Large case, rated “only” IP67
For it’s size (140x40cm) and how I use it (standing on it, deforming it, crashing into the water,…) it holds completely waterproof, like not a single drop of water inside after a session…
On the other hand I had IPx8 leak without any abuse…
Most critical in our use I think is the splash / high pressure when the case hits the water with speed
For that it’s just important that the seal is protected from the inrushing “wave” by a lip, labyrinth or something alike
Do you know any reputable company that offers the same product as both IP67 and IP68?
Problem with the VX3 is not the rating, but that it does not stay waterproof over time. Likely because they use rigid potting that creates cracks or cavities over time.
Pretty sure you can submerge a new VX3 in water for 30 minutes without any issue at all. Done that multiple times.
When I still used a Camdenboss box, I never had any issues. If I could choose, I would still take the Peli, because it has those rounded edges. But I do not think it is “more” waterproof.
No I don’t but I doubt any company would say they do that😀
I was attempting to say that the IP rating is an information point for the purchaser not a guarantee of performance as there really isn’t much oversite over the manufacturer.
As @ludwig_bre points out the use case is way outside anything a lab would subject a product to. Immersing a product in a bucket for a specific time period does not equal a violent impact during a crash😉
