the zener regulator an sLM317 both have the voltage excess being droped and multipied by pass through current. so i think your inthe same boat as before 1 amp at 14-5= 9v x 1A means a lot of heat.
I realise that, Patrick. I was just wondering if the principle would work, as it's so simple...just two components.
As it will be running off a car battery, in a car, a bit of wasted power isn't really an issue.
I'd like to refine it a bit, but I just wanted conformation that it's possible to charge lithium ion batteries this way....I was previously under the impression that charging lithium batteries was a 'black art'.
(there is plenty of power to run cooling fans, etc, from 12V.)
Why overcomplicate things?
