| Your description does not make sense. How are your batteries connected? A schematic is worth a thousand words.

HI Bonkk,
At the moment I have the 6 batteries connected in parallel.
I would like to charge all 30 batteries I have also in parallel at one time, if this is possible.
That is the reason I posted the question.
Regards

| I guess you can connect 30 batteries in parallel and charge it (be careful during paralleling - big currents will flow during commutation).

Hi,
People use larger battery banks what you are asking for but one should be careful in handling those.

Why are you intruding in the discusison already in the way?...Please do start a separate thread Under "Electronic Elementary Questions" or "Analogue circuit design" for beter responses. Good luck
