I have found this come under heading might be useful someday

Hope the link works

A good article, but the first query on scrolling down says that some people should not be allowed anywhere near electricity. -
Quote
if two batteries are connected in parallel and they have different voltage ,so which one voltage will be shown on AVO meter, and merits and demerits

Action used to do a nice little circuit allowing two batteries to be connected in parallel.   Pete

Never mind "used to", young Mr Munday! http://www.componentshop.co.uk/p103-parallel-power-board.html (http://www.componentshop.co.uk/p103-parallel-power-board.html)  Still available AND for no increase in price!

I agree with Malcolm in that no-one who regards a basic knowledge of DC electricity as optional should be allowed to make RC model boats. I've even heard the subject dismissed as "I can't bothered with all that technical stuff". If it really was rocket-science then I'd have taken up basket-weaving years ago.

Instead I wrote this, which some folk have apparently found useful http://www.modelboats.co.uk/news/article/but-i-don-t-understand-electronics/18054 (http://www.modelboats.co.uk/news/article/but-i-don-t-understand-electronics/18054)

Never heard the  word "serial" for "series" connection. Is this a British thing, or is the guy smokin rubber?

I think it's 'American English'. The website is "sponsored" by Cadex Inc, which appears to be a US company. I think 'serial' sounds a bit odd - I keep thinking of 'serial killer'!

Probably using computer terminology for serial and parallel ports and buses.

For someone who has been  in the electrical industry all his working life, and worked with electricity long before that, it sounds like some one is reinventing the vocabulary here. No, its not even Amerispeak either. Strangely, they use the same terms we do in this instance.
thanks

As per the Oxford dictionary, there are several interpertations for each word, however, I think this about covers it for each:

SERIAL: 
 adjective1Consisting of, forming part of, or taking place (http://www.oxforddictionaries.com/us/definition/american_english/place#place__67) in a series: a serial publication (http://www.oxforddictionaries.com/us/definition/american_english/publication#publication__4)


SERIES:
 noun (plural same)1A number of (http://www.oxforddictionaries.com/us/definition/american_english/number#number__10) things, events (http://www.oxforddictionaries.com/us/definition/american_english/event#event__4), or people (http://www.oxforddictionaries.com/us/definition/american_english/person#person__5) of a similar (http://www.oxforddictionaries.com/us/definition/american_english/similar#similar__4) kind or related (http://www.oxforddictionaries.com/us/definition/american_english/related#related__4) nature coming one after another (http://www.oxforddictionaries.com/us/definition/american_english/one#one__37):


Since "series" has always been used as an electrical term since circuits were started to be built, I don't see why the term is changing in some areas..
