Rip off?

One big UK dealer is asking for £274.99 for an ECO Worthy 100Ah LiFePO4 battery with charger. The same battery from Amazon (without charger) can be bought for £169.99.

Hmm.

Eco-Worthy batteries

MLS is doing a promotion  of /P gear including the IC705, no doubt expecting many IC705s to be traded for the new Yaesu field portable transceiver next year.

One of their items is the Eco-Worthy 30A, 12V lithium battery pack for use with the IC705 out portable. I was about to blog how expensive this was. Then I checked on Amazon and the battery was £99.99 to which you have to add the charger. Overall, not a bad price from MLS with the charger if you really need a 30A battery. However, there are lower capacity batteries and chargers available from other suppliers for far less.

UPDATE 0827z Sunday:  Steve G1KQH says the same capacity battery may be bought elsewhere for far less. Shop around?

Volta's battery

 

This dates from the very early 1800s. It may be the first battery ever made.

Electric cars and batteries - NOT amateur radio

We are still awaiting a breakthrough in batteries for electric cars. Lithium, used in most (all?) electric vehicle batteries is a rare earth material in short supply. These batteries are expensive and big. There is also the issue of charging.

A breakthrough may be on the way promising much better ranges, less cost, and fast charging times. Until this happens, I cannot see a tipping point when there is a really big take-up of electric cars.  Imagine - far less expensive electric cars, very infrequent charging, long ranges. It will happen.

Electric car batteries - NOT amateur radio

Steve G1KQH sent me this cartoon yesterday. 

There is a very serious point though. Until EV batteries are made from far more common materials and have a far greater range, I cannot see EVs being a disruptive technology like flat screen TVs or digital cameras. 

This will come with investment and drive. At the current rate, the Chinese will be the first and we will be way behind.  We need this if our children and grandchildren are to have a planet.

In my view, I suspect this will come before 2035 and we will all be amazed that we used fossil fuels at one time. 

Battery power suggestions

Thank you for your suggestions This sounds like something I should try. Now  I need recommendations for battery packs and chargers! I expect eBay will be the best source at the right place.

Wireless charging from roads - NOT amateur radio

To me, this has to be the answer to a carbonless future with regard to road vehicles. Southgate News reports on trials in France and Israel where the road has embedded wireless charging for road vehicles. This means smaller, lighter, batteries in the vehicles, a longer battery life, and greater range.

Huge leap in rechargeable battery technology?

The ExtremeTech website has reported a possible major major (i.e. game changing) breakthrough in Li-Ion battery technology with the headlines:  New lithium-ion battery design that’s 2,000 times more powerful, recharges 1,000 times faster

If this turns out to be technology that can indeed be commercialised, then just imagine the possibilities: (1) electric cars with far lighter batteries, or electric car batteries with much greater range, (2) mobile phones with tiny batteries that can be charged in a minute or so, (3) portable HF transceivers that are half the weight of the FT817 but with batteries that last for days between charges.

It all sounds just a bit too good to be true, but I am sure this was no April Fool's joke.
