Snips – News For Scotland – 1st September

The news headlines:

  • Good news for the two-metre band
  • Syllabus 2019 mock exams now available
  • Five UK places for YOTA Winter Camp

Many Glasgow amateurs and surrounds were aware of the passing of Denis – MM0DNX on the 20th of August, with his subsequent funeral taking place at Daldowie Crematorium on Wednesday 28th. It’s a great credit to his club, The Mid Lanark Amateur Radio Society (MLARS), that so many members were able to attend along with other fellow amateurs, to pay their last respects. Christine (Denis’s XYL) and Denis’s family were truly heartened, and their spirits were lifted somewhat with the turnout. A credit to our hobby.  Although not a member of WoSARS he was well ‘kent’ in the Club and there is a wee tribute to him on our Website – HERE .

Why Balance Batteries – Specifically Li-Po’s?

 

A question was raised at the Club recently as to why we balance Li-Po’s and not cells such as NiCad or NiMh’s?

I certainly knew it was ‘done-practice’ in order to obtain maximum performance from Li-Po’s, but why not do the same for other battery types?

There is a good write-up in Wikipedia (click the graphic) as to why this is done.

And – the bottom line – it appears, that it could be done with most types of battery packs, which in the end would improve their performance and extend their longevity – just as Li-Po’s.

So now you know!

Edit 05/07/19:

Following on from some questions raised on our Members Forum #73  –  HERE is some additional information about Active Balancing and associated circuits, courtesy of Analog Devices.
