I am thinking about building a battery with 52volts and 24 ah. But I haven't found a good box/case for this purpose that is not too expensive.

What type of box have you guys used for this purpose when you have built big batteries in the past?
 
With 5P, five 4.8AH 21700 cell will give you 24AH, The Samsung 50S, which is 5AH and an amazing 25A discharge are on sale for 5.99 each. Yep, that's $420 in cells, but I wouldn't buy batteries from Uncle Ali.

Aha are they really so much better than the Ali-cells? Price is almost triple. But perhaps it is worth it?

Building 24 AH with these would make for a very good battery perhaps?

52V24Ah pack with 21700 4800mAh in 14S5P configuration, so 70pcs 21700 case: Polly DP7-21700

Has anyone on this forum had any success with 21700-cells from Aliekspress? I am curious since I am looking for that now.

I have found pretty decent 18650-cells in there(for their price) but haven't found any very good 21700 yet that people really like and order a lot of.
 
Since I will begin doing this the first time with 18650 cells. 91 pieces. I need some help to understand te wiring of this nickelstrip and case. Can someone tell me if I have thought about this correctly? Like I've drawn the image.

It was little hard to find that nickel configuration: https://m.aliexpress.com/item/1005002363016898.html
Case is 91pcs and 14S6P is 84pcs, so there are 7 empty slots
