I am jonesing in the worst way now to get some lithium power in this EBR, but I just cannot drop $4K for all the cells I need to get to 7.2 kw.
But I sorta had an epiphany just a while ago when I was pricing them out, again, for the 100th time, just in case the fundamental principles of mathematics had changed and I could somehow afford a batch of TS 100 AH cells.
Let's say I went with Headway cells instead, and I got 48 of the 10 AH cells. That would get me 20 AH for a little under $1K. I could probably swing that. If I add depth to the pack 24 cells at a time, would it matter if I had a mix of cells with different levels of use? Would it matter if some packs were 10 AH and some were 16 AH?
I also like the form factor flexibility and the higher performance, but most importantly, it seems like it's an approach I could build on a bit at a time.
