Charging SLAs from DC Answered
Hi Instructables community!
I am building a K9 robot - one that is going to be covered in solar cells-in such a way that I get a voltage / current ratio of a pretty high number. I plan to charge my SLA partially via these cells so I can lengthen the space between charges. Unfortunately, my 6V 4.5Ah SLA battery is charged via a plugin adapter and I do not wish to pull it apart unless there is no other choice - so is there are a way I can charge my battery from a constant DC voltage? If so, do any of you know what voltage/currents I'd need to feed it?
I can get most any current/voltage specs via transistors and voltage boosters - just I don't know the equation.
Thanks for all your help!
