Dear all,
thanks to Will Prose's great videos regarding LTO cells, I decided to run my photovoltaik plant on 40Ah LTO cells !
So far so good - I have ordered 10 Sets of 24 = 240 cells and now I want to test them before installing them, so that I do not get a buggy cell in my setup.
So I have ordered the cheap (40 US$) aliexpress capacity tester from Wills Video video to chek them one by one.
To be on the safe side I would like to operate them in production between 2.7 and 2.1 volt.
And here my trouble starts: I load one cell up to 2.7 Volt, connect it to the capacity tester and set the low voltage cut off limit to 2.1.
As soon as I turn the discharge amp on (not more than 5 A), the voltage drops down to 2.2 or lower and the test stops immediately. Thats a bit ... annoying
Could you perhaps give me a hint what values make sense for such a cell by cell validation and what limits I should use for test and operation ?
