Hi, my name is Victor. I'm german but try it in english.

I have a solarcell and an TP4056 IC for example. (I know its not good 
setup). The voltage is termined by IC and the max current by resistor. 
Althing work (not fine) but "ok".

My question is what happens with the 1S 18650 cell with that setup? The 
CV ist ok. But there is no possibility for CC.
What changes with the 18650 for example: Lifetime? Capacity? other 

Is a fluctuating current input so significant for e.g. NCR18650B Cell?
Why CC recomend? If you can give me a good link in german or english 
with researches or information from a producer like panasonic/sony/... 
would be great. Or if you have do test and could share would be really 
I couldnt found something like that in web.

Best regards
