it may be that I finally found the reason for the problems I described in my previous posts:
I cut any connection between data1 and data2 to the rest of the PCB and shortened both.
Now the camera goes into charge mode for a short while.
Today I will buy fresh ENELOOPS and will see, whether I can perform a full charge of my camera
In this context one thing came into my mind:
ENELOOPS have a relative stable voltage reading under high load, which implies a relative
low internal resistance. On the other hand -- compared to alkalines, they have a lower overall
voltage of 1.3V in opposite to 1.5V.
The FAQ/Battery Guide does not answer my question....
Using two ENELOOPS gives me the benefit of a low internal resistance with the drawback of a lower
overall voltage compared to using three ENELOOPS with a higher overall voltage and the drawback
of an internal resistance increase by 33% compared to using two ENELOOP cells.
What shall I do?
By the way: I read (in the FAQ or the Battery Guide) that the input voltage to the MintyBoost
should not exceed 5Volts. Furthermore I read that one is allowed to use 4 cells in serial as long
as they are NiMHs and no Alkalines. Freshly charged NiMH often have a voltage of 1.3 or more.
4 x 1.3 exceeds 5Volts. Does that harm?
Thank you very much in advance for any help!
