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.
I have an MRC-89 Superbrain battery tester. It is built for R/C cells
and batteries up to 20aH. These sell for about $100. It can test
higher-capacity cells, but its amphour counter will "roll over" from
199.99ah to 0 so you have you have to add the excess beyond this.
It is limited to a charge/discharge current of about 5 amps. They claim
more; but it will overheat if you do and shut down before the test is
complete.
I built my own tester for higher currents. It goes to 100 amps. If you
like building things, I could supply the PC board for it.
