I’ve hit a snag.
@NoWind - should I have expected some long M4s to fasten the wheel drives with?

Have you figured out how to mount the wheel pulley to the hub yet? I have an e-toxx MBS chain drive kit on the way and am very interested on the mounting procedure for the pulleys to the hubs as well.
I would first mount the hubs with the stand offs than the sprocket. Get some m4 screws which are 5mm longer. Should be fine than.
Nice build buy the way

Vtc6 all the way!
Why, to get a capacity loss of over 25% after 50 cycles?

IIRC the 30Q has a loss of aprox. 5% after 50 charges. Their is no better 18650 cell for ESK8 right now.

what enclosure is that 3d servisas on the back?
That graph say it starts at like 2300mah. The vtc6 is 3000mah. Yes from what I have seen the 30q has a better life cycle but the vtc6 has a higher output. I currently only have 30q packs but I just bought a ton of vtc6 cells for super cheap. I will soon be able to test for myself if they truly degrade that rapidly.
They charged the cell to a certain voltage and than compared the life cycle.
The result was after 50 cycles 1727mah 74,18% -0,99% for the VTC6 and 1934mah 86,92% -0,49% for the HG2.

Any context around that?
What was the discharge/charge rate at?
Does it really make a difference in our not linear discharge?
Wouldn’t be so sure about it.
I definitely would put vtc6 on one level with 30qs.
Winner is the one which you can get cheaper.

Take the test with a grain of salt. The test I just looked at the vtc6 cell was incredibly abused at a constant 15a drain and 4a charge for 50 cycles and only lost 11% capacity. The 30q only lost 6.9%. There are pros and con to every cell. Vtc6 has a higher discharge rate, less voltage sag. The 30q has longer life span by a few %. So it lost 11% capacity after being completely abused. Esk8 you aren’t abusing the cells anywhere near 15a constant discharge and nobody I know charges 4a per cell( that would be a 20a charger for a 12s5p). I myself use a 3a charger so thats .67a per cell. There are just trade offs between each cell.

Also I got the vtc6 cells because I got them for $2.59 per cell. The cheapest I can find 30q cell is $4.50 with moq. Fyi nkon doesn’t ship to the United states anymore so I got the best deal I could find and stocked up with 400 cells.

Most manufacturers take the 30Q for reliability reasons and the good life span.
It is by far the safest all around cell out there. If you have lower power setup or very big batteries (8p+) you can also use 35E. Samsung is leading the battery industry anyways, so there are multiple reasons to get the 30Q over any other 18650 cell.
Ok availability and price are legit reasons to go with another cell. A good over all alternative is the 40T if you can go 21700. Sanyo 20700B are also great cells, but I wouldn’t recommand any other cell for general purposes.
The VTC6 is a great race cell though, if you want to go with LiIon. But in race cases I probably would prefer LiPo anyways.
Sorry if I… but there some things I don’t want to let stay here like it is
Any backup to this statement?
Like any other cell which has around 8-10A.
By the way I personally wouldn’t use the 35E even on a 8p pack. Maybe on a 10p plus pack, but than there still cheaper options available.
No. There is no advantage on 40T cells over your beloved 30q. The only advantage they could bring is if you make a flat pack and can’t double stack but fit 21700 cells.
Compared in proper relation the 40T will lose over the 30q.
No? What’s with vtc5, vtc5A, lg hg2 just to name a view.
It’s even not the best cell Sony sells, so no it‘s not a race cell.

Yes, like I said. Check out what most companies are using in their ESK8. Even in DIY it is the most used cell. It’s proven tech.
ok
Sure. It depends what you are meaning with proper relation. The 40T has higher current and capacity per l and per g.
They are good cells but wouldn’t recommand them if 30Q are available.
ok.

Ok that’s an scientific evidence 
Ok. Let me check, 40T 25-30A discharge 70g… 30Q 20A discharge 50g … 0,42 to 0,4… **you right **
Looks like a significant advantage.
Let’s just have a short look at the price tag thou. 40T 4.75€, 30q 2.80€ (nkon price) that’s 0,06€/g vs 0,04€/g so 1/3 more expensive.
