I want it to be short enough for easy travel. I want it to be light enough for maximum distance capacity. And the only efoil I tried was this lenght.
What is your logic behind the 14S battery?
I want to have has much power I can when I will want to go full speed. I tought long and hard on a 12S10P instead, but for 20 more Cells, I said to my self: go hard or go home haha!
Have you worked with fibreglass before?
No never. I am a quick learner so I expect myself to be able to do a good job.
You’re better off with the 14s10p at a higher voltage for more power at start-up with less amps. You will get the same Wh out of a 14s10p as a 10s14p, distance will remain the same.
A number of us got 10S11P premade packs of 21700 cells from Battery Hookup. My initial intention was to build 12S packs from the cells but I found the packs worked for me as is during testing late last fall before end of season.
Lots of posts, threads and opinions here about battery but imo you should think of the efoil in its entirety to end up with something your happy with.
Getting a board, battery, foil, motor, prop, controller that match your weight and riding style - waves, flat water cruise etc all have to work together.
16S in NOT wrong for a big rider on a low volume board who likes to go fast as they can. However that combo for a light rider on a high volume board who likes to just drive around cruising it’s likely not required.
Ultimately for you to decide what is BEST for you. Just keep reading and using quality as your baseline!
I am building the battery now. My first idea was to use cell holders. But after I received the case to put my battery in, I was a Little too tight. I had to let go of the cell holders and I hot glued the cells tight together. Problem now… my nickel strip was to be use with cell holder and without the little spacing between en the cells, the holes on the strip arent in Line with the cells.
Does it matter? Can I still use those strips ?
Your board looks nice, but I really hope your hatch will be watertight.
We have been testing many versions like yours, but have never been able to make it anywhere near watertight!
These strips look like 18650 strips and you have 21700 cells. I don‘t recommend short cuts on the battery, it won‘t pay off, better order the right strips, 0.15, better 0.2mm real nickel.
@Foilguy I think I already watched it 10 times haha!
You are right, better safe than sorry. I ordered new ones.
Thanks!
@sat_be its for 21700 with cell holders. I found some strips made for 21700 without cellholders, the gap will be perfect. thanks for the insight, no shortcuts is always safer!
@Pavel If I use cellhoders to add space, my case would be too small
Efoil building is a challenge after another, every damn day haha
Dude, if you line up the batteries in this wicked bee cell pattern, then when you’re putting together a 14S10P battery, you can totally save, like, 20% of the space, man.
