Hi everyone,
Haven't capacity tested cells in almost 2 years now, have probably 2500 to go through (to match the ~2500 I went through last year, for an electric vehicle build).
Last year I'd bought a pair of Zanflare C4s because they were cheaper than the Opus 3100s.
This year, I don't want to spend month after month testing cells, so I was hoping to add some capacity. Maybe at least doubling my pair of Zanflare's.
...
However, it looks like prices for Zanflare C4s are like, $55. Meanwhile, Opus 3100s are $23. So I can literally buy 4x Opus 3100s for the price of adding 2 to my existing 2 Zanflare C4s.
But, intending to use them all in a single pack, I'm skeptical about the measurements of the Zanflare C4 vs. Opus 3100, since I'll be doing 2500 new ones and adding them to 2500 I've already measured from last year. Also, I let 2500 cells sit at 4.2v for 1-2 years, I imagine their capacity is going to be declined from the ones I'll measure this year. Hrm. Thoughts? What should I be buying?
And, that also makes me wonder, what else has changed in the last year or two? What's the new meta for cell salvaging?
(This'd be a great FAQ item, if updated somewhat seasonally).
Also, anything else that the community has kinda worked through as best practices or purchases? For example, last year I bought 4x5 plastic grid holders for cells, as that was the cheapest. Still true this year? Are there bigger sheets that are more cost effective? Etc.
Would appreciate you guys giving me a rundown on what's up.
