Samsung SDI upgrade

From a remote, unkown place somewhere in Europe, our friend M. send us this interesting upgrade with Samsung SDI modules.
Each modules is 12S 2kwh. There are 4S 2P modules totalling 16 kwh/48S. Superb job, really inspiring!

Re: Samsung SDI upgrade

I like the use of the original welded tab cell modules.
That's heaps neater than my attempt with bare 94Ah SDI cells with bolt terminals:

Re: Samsung SDI upgrade

Hi R,

Could you provide datasheet to this cell ? Are you voltage and current load to Samsung SGI cell (178wh) ?
regards

Re: Samsung SDI upgrade

Hello, I have been riding a Vx-1 with a Samsung-SDI battery (36s1p, bought new in a BMW spares shop) for almost four years. It performs very well (I have several videos showing the perfect cells balance after a middle range ride, some 80km).
Although I bought 4 modules (94Ah), I was told that only 36 cells could be arranged in the box (disassembling cells out of modules was actually a nightmare since they are hot-glued together). My concern is about
the orientation of the cells in these pictures: in my battery they are placed with tabs up, while here I see tabs placed on the side, is it correct?
