NIMH Charge in series with IMAX B6

Asked earlier about charging 4 aaa nimh in parallel and found it was a bad idea.
But read I could charge in series.
All batteries were used together in series at the same time.
Started in manual mode.

Hooked up 4 aaa 1000 mah in series to the IMAX and it has been working without hot batteries.
.2 amps, voltage on screen at 5.87.

Will this be OK and stop when done or should I intervene ?
Or should I not try this at all

there are already 3 threads by you ;)

NIMH Charge in series with IMAX B6

One was about parallel, i did not even know to ask about series and no one volunteered.
Not sure about first, can’t find it but it would not have been about NIMH
Series was mine and was not trying to be a pest.

Guess it’s time to just not post ?
Probably better to find out myself instead of open myself to criticism.
Thanks for the warning
