Hi guys,
This is my first post. I hope it is in the correct thread.
I am puzzled and confused. I have been doing some tests which I figured would be seemless and obvious in the pre plan.
As you would with a 1.5v battery, add 2 of them together, you get 1.5v but for longer life, add more, more life..
If you cross connect them, you got from 1.5v to 3v, 4.5v, 6v etc..
If I test a cell, which I might add is pulled from a small garden light - a £1 job.. I get 2.2v.. My confusion is when I cross connect them, I expect to get 4.4v and so on + + +..
I am a technical person, I take things apart cause I want to know how they work etc..
This test seems a simple and obvious thing which shouldn't have anything too difficult involved in my plan to gain 12+ v..
When I test them in a parallel structure they read.. when I cross connect them as a pair, they read 1.7v from original 2.2v.. if I add more, it goes further down till it no longer reads..
I wondered if my multi meter was not working, I checked a 1.5v battery, reads 1.6, I added another, it reads 3.3 ish, so my understanding is proven to me but my confusion is still that.
I might add, I have a PWM controller coming in the post, I have since learned about MPPT, this will be the one for a proper set up. I intend on getting a panel and deep cycle batteries, I've been researching but this is pickling my brain, what am I missing???
