Here’s a picture of the last compartment with 12 cells in it. So you could probably do a 14S6P if you wanted to.
@campbellsoup go for 18s4p instead of 12s6p. Same number of cells but you’ll have more available force going high voltage.
Ive been debating which way to go… I just bought SKP 173 kv motors. Maybe he hasn’t shipped but I would want to go down to to the 151kv right? Also I was going to go Makerx dv6 but that doesnt run 18s. What ESC are you running?
18s all the way! 151kv would be perfect for 18s. SKP solo is a solid choice for a high power and reliable 18s ESC. I’m running the makerx d100s, which is also a good esc.
173kv would also be a good choice, but it depends on your gearing and what top speed you want. The 173kv motors will accept marginally more amps before overheating, but we’re talking very little difference there, and you probably won’t be overheating motors on 18s anyway.
I have a Maker DV4 from another build, so I am just going to use that (DV4 supports 12S).
For my style of riding, 12S is plenty of voltage.
I thought about 18S4P, but the cost goes way up for high voltage ESC’s. And I just like to cruise and go fast once in a while - so it all depends on what you are trying to achieve with your build. That’s the beauty of DIY - you can make it any way you want.
If I already had a DV4 or DV6 i would for sure stay 12s. I could try the D100 because it is only $20 more then the DV6 but it seems that the DV6 is a newer platform? Not sure what you gain though. SKP Solo is a good amount more then anything Makerx so its out of budget. I also have someone offering a used D100 for $175 but Again seems like maybe a generation older then the D100s? not sure
@Shadowfax what do you really gain by 18s feel wise? about how much more power do you get over 12s? If its marginal and just more of an efficiency thing I will for sure stick to 12s just for more options. If SKP 173kv motors will work fine at higher voltage I might get a D100s and go for it
it’s not a marginal difference - you gain 50% more available speed by going from 12s to 18s. You can also increase the gear ratio on the 18s board to increase the amount of force at the wheels by up to 50%.
Put simply your 18s board can have the same top speed and 50% more force, or you can have the same amount of force in a board that goes 50% faster than the 12s board.
If you want to understand how much more power/speed you gain by going to 18s, play with the ultimate esk8 calculator.
Ahh got it. I should realistically go 18s then. Might as well do it now so I don’t regret it later. I guess I have to go with the D100s since its marginally more then the DV6. Im assuming the SKP 6485 173 kv i got will hold up just fine
They will, but hit up @Skyart if you want to swap for 151kv. If you are on belt drive it might make more sense to go 151kv. If you are on a gear drive that can do 5.2 or 5.5 ratio, you’d be solid with the 173kv
I have the SKP 173kv on my nazare with 5.5 ratio gear drive and top speed is ~40mph
Its not. 12s6p won’t fit in the configuration you have shown it.
If you get creative you can stagger the cells a little, and that would allow it to fit, but you would likely still need a slight gasket.
I believe you could fit a whole lotta Molicel M35A 18650’s in the Lacroix Enclosure also. I think the Flux Motion AT2 still has the 18650’s.
But if I didn’t already have a couple of unused 12S VESC’s laying around, I would probably go with the 18S4P configuration discussed above in this thread.
Is there space to “wing” up the last cell like what I had alex do on my moonshine build?
Makes for a bit more tedious nickel cutting, but most enclosures have more height on the perimeter.
I think it’d be better off on like the second last cell, or even better, multiple cells. In any case, i think it would be difficult to achieve without a gasket.
I think the depth across the deck/enclosure would be basically the same all the way across, as it’s right at the transition to the nose
I don’t think he is planning to use that last row at the front. See his picture here (using space that is not normally used for batteries in the croix enclosures):
12s6p will fit fine with that plan. I think 18s4p is a better way to go, or even 20s4p.
@campbellsoup you could easily fit 20s4p in there if you put two p groups in the front compartment (with the cells next to the ESC and BMS like in @LAKESHORE pictures). 20s4p in that enclosure would be easy to do, and it’s a great battery size that will get you 30-35 miles of range.
I just finished my Lacroix build last night and it will definitely fit a 12S6P of 21700’s. In the front enclosure compartment, I just had to offset the 2 end cells (instead of flat) and I just spot welded them using 30mm nickel. It was really easy to do.
