Have a look at the iCharger units made for RC packs. The
charge/discharge/cycle modes show elapsed time, charge current, and
total mAHr. The iCharge 206B that I have is $112 at www.hobbyking.com
Note: all iChargers require an EXTERNAL DC POWER SUPPLY, and the power
supply voltage may limit the maximum charge/discharge current of the unit.
iCharger 206B specs:
Requires 10-28V DC power supply
Will charge up to 6S Li, 17S NiMH/NiCad, or 2-24V Pb
20A (300W max) charge
20A (20W max) discharge - 300W with external load
Internal resistance measurement (haven't tried this one)
Temperature probe/compensation
Programmable settings
36 Hour data logging - transfer via USB
There is also a "regenerative discharge" feature that discharges packs
by feeding power back into the power supply. I couldn't find any
information on the max cell capacity cell it will handle. Maximum
capacity is not listed in the manual and examples in the literature only
show data for 5 AHr or smaller packs. The iCharger website is
www.icharger.co.nz

Is there an atuomatic siingle cell LFP cycling capacity tester ? out there ..
Like an RC hobby gadget that would work with even a 40ah to 150 ah cell,
$100 or less, maybe 5 - 20 amps, so it could work, maybe 2 to 24 hours, and
would digitally tell you, your AH capacity ?
Itd be nice to how the cells are doing in our pack.
