Hi Erosennin and Eric
Thank you for your replies.
In the past I have thrown together a single cell recharger based on the MAX1555:
https://www.electro-tech-online.com/custompdfs/2007/11/MAX1551-MAX1555.pdf
This was ultra simple. I was recharging a 1000mAhr battery.
Thus the rate of charging using the MAX1555 (see page 4 graph on top right): 280/1000=0.28C So I guess that this is ok?
Now I need to charge 2 batteries in series.
I have been trying to come up with 2 MAX1555 circuits working separately on 2 batteries, but the batteries are connected.
The charging will be: 280/170=1.65C so this is too fast?
However if I refer to that graph, I see that the MAX1555 will cut the current once a certain V is reached.
Basically I am very confused on two levels:
(a) Can 2 MAX1555 in "separate" circuits be used to charge 2 170mAhr batteries that are connected in series?
(b) Is the charging rate too fast?
Thank you for all your help, I hope that you can help me understand this problem.
Best Regards
