Would like to collect reco's here for "reasonably" priced testing and data-logging equipment,
let's shoot for altogether well within $500, not counting the target PC and Logview type software producing the final charts.
Chargers like Junsi iCharger and FMA/Revolectrix Cellpro, maybe ISDT are of course one important category.
Another is CC electronic dummy loads, especially those able to go higher than say 20A for true stress testing of sustained high C-rates.
One class I am particularly interested in, is "passive" or pass-through logging hardware, that maybe does not itself create or control the charging energy or discharging load, but simply records the volts & amps data over time, for later transfer to the PC for analysis.
Really hoping to find still-accessible sources for the old-school quality versions of (Japanese?) CellLogs?
For true-capacity testing, I do not like to assume coulomb-counting gear is accurate enough for that, so besides the CC load regulation, the ability to automate and precisely time the lower-current draw-down over, say 3-5 hours is important, ideally more elegantly than using a smartphone to capture photos on a timer.
And finally of course the temperature change logging hardware so the varying C-rate can be correlated with its impact on cell health and longevity.
Obviously this thread should keep a focus on the testing process, so general discussion on different testing approaches, defining related protocols etc is fine.
But ideally the intention here is to build up a comprehensive listing of suitable hardware, and discussions comparing the various units' costs/sourcing, features and capacities.
Extensive sub-topics about the implementation details for a particular piece of hardware could perhaps be split off into a separate thread for each, to keep it useful for us noobs seeking an overview.

Good stuff.
