Hi,
I have built a circuit based upon an oscillator and a decade counter to flash six LED's in sequence. This circuit requires 5.5 -6v to operate and draws no more than 15mA.
The circuit when in operation has to run for several years (day and night), it needs to be isolated from the mains supply and also maintenance free.
At the moment I have a 6v 200mA solar panel and five 1.2v 3000mAh Ni-MH "AA" batteries. These batteries I had purchased for another project and had them to spare.
If I were to make a 6v battery pack from these five batteries would it be possible to keep it at 6v throughout its lifetime, by connecting the solar panel to them.
If I were to connect the solar panel direct to the 6v pack, would it be advisable to fit choke or current limiter to aviod overcharger the batteries?
Also in the night time situation will the solar panel have a reverse effect and become a load on the battery pack, (are solar panels resistive without light?)
At night will it need to be disconnected from the batteries?
Any help appreciated,
Regards NM
