Mornin all, I would love some confirmation and any input on this subject.
I read neptronix's tuturial on lipo and the wiki, and alot of other threads but have not found what I'm looking for.
Battery 'packs' to be charged: 18s of 6s 5.8ah or 16s of 4s 5ah. Each pack may in the future be doubled in capacity to 11.6 and 10ah respectively.
For universal low priority charging and balancing: an icharger 106b 6s 250w. I see this as an essential part of charging and maintanence, but definitely slow and a pain to rewire the series packs for charging, and I believe it's unnecesary to do so on every charge.
Enter bulk charge. If you wanted to charge 64-80v batteries having 5-11ah, what is the setup of choice?
before anyone mentions, no I don't want an expensive 4 channel charger and am not considering a bms. (these are great, but I prefer to be my own bms, because I find kiss is always more reliable)
I am considering 2x of one of these. One is a used meanwell brand with a little less current, the other is a little less$, new, and more current.

If there is a tuturial thread on these in series please link it!
Here are my questions: what would be a better choice? (ie is the namebrand more important than the other criteria?)
Do most of you target your batt charge rating specifically for charging? Mine are 2c, and I assume 1c is double the time to charge.
So if one planned on 10ah batts, would one seek a 20amp charge setup? Examples?
If there is no chance of exceeding the 2c batt rating (as in the case of my proposed setup), I assume a board like fetcher's limiter is not desirable and/or necessary? Why would you use one, in what circumstance?
My assumptions are that either of the linked psu is considered cc/cv and to series them for proper voltage I will at least need to isolate grounds. Is there anything else to know?
