It might very well fit, but I would recommend using something other than 35e cells. 30Q is much more suitable for such a low-P pack.

(35E cells are only good for <10A per cell, whereas 30Q are good for 15-20. You lose some capacity - 3Ah/call vs 3.5 - but you gain a lot of power, and greatly reduced voltage sag.)

Good to knew, this deck is really too thin for any build 40km+. Do you know any deck similar to this that can fit 21700 cells?

I want to use that battery pack for onsra dd kit. They are using 12s3p 23e in onsra black carve so I thought that it would be enough.

Hello friends, I have a question. How many amps can a single nickel strip manage? I am being told by a supplier that 60 is too much for a 10s4p battery in single stack, and that battery would get too hot. How true is that statement? Any possible solutions?

Yeah… Are you really sure they are knowledge in this field though?

I found this, so it makes no sense. Should handle more than 60 cont

We will see haha. I will test the shit out of it

Draw a picture for us of the nickel/cell configuration and note the thickness.

Maybe they are using thinner strips.

Ok this is a battery builders club and you’re asking about the specs that a battery you purchased somewhere can handle? Why aren’t you posting pictures of it?

Typical 10s4p config. They were worried that it would be 60 amps cont, but it should still handle it right?

That pack is straight up badly made imo… I would barely trust it at 60A and it needs to be padded and in a super stiff deck and enclosure.

I’m going to let people who have actually dealt with batteries is exactly like that handle this

Deck is super stiff and it will have heatshrink on. What kind of padding are we talking about?

I just mean it should be very tightly held with foam and compressed some. If the pack gets vibration it can loose cells in a Pgroup and then the pack will be unbalanced and useless.

Just gonna hope there is isolation between the cell casings too.

All right thanks man.

Wanted to bump this down, I edited this original post with more accurate info since I just noticed another price change on BulkBattery. This time it’s much more beneficial as our communities current golden child cell no longer has a price increase, but a price decrease!

I printed that vice too, handy little thing

I built a pack for someone with a similar situation. His weight may be on the battery sometimes (Raptor 1 deck) but theres zero overlap on the balance leads, and they are sandwiched between fishpaper. I think it will be fine. Worst case scenario a balance lead breaks from being squished (unlikely I hope), but let me know if you disagree

New thread for battery pricing? :eyes:

Cells aren’t supposed to be like stocks lol. Bulk didn’t raise prices one time in 2020, so these two price changes really surprise me. I figured it was import tax increase or something. If the trend keeps up not a bad idea to start one.
