they said that 10 years ago but when all cars are limited to 15 mph it wont matter anyway every batt will run out and loose its capacity over time and the manufacturers will make it impossible to use 3rd party ones and will make them so expensive after 5 years a new one would not be worth it or just not be made anymore.

 

it is all about profit and subscription fees and fully tracked and controlled so just get a horse but the vets fees are expensive so if you get 15-20k out of it just blow its head off with a shot gun and make some burgers

.......if there's a fault (short caused by moisture in this case perhaps), so maybe absence of such means it's safe to use? ..........

Just to say that water has, in electrical terms, a resistance, so technically water ingress won't cause a 'short' circuit.

 

I've no intention of putting this to a test, but I'd have thought that water across terminal that resulted in a high current would see that same high current quickly heat the water to steam thus eradicating the 'short' - just a theory...... .

 

The purer the water, the better its insulation properties. As a radar mainter of many years past, I remember one particular radar set where the 'final stage' magnetron, which ran at 100,000v, was cooled by pure water being pumped through the device itself.

Well, the LEDs stopped flashing for five minutes, off for five, on etc. after it dried out... so given that it was exposed for three weeks to rather a lot of rain water (lead? less so these days, carbon?) which isn't pure, and maybe mud, which may have been further contaminated by some ionic contaminant inside the power bank, could have caused a small current to flow somewhere between some component or other, or perhaps excess moisture affected the electrical properties of some component(s) leading to flashing LEDs? What's your theory? It was only a tenner, I doubt if this power bank contains a moisture sensor - I'll have to take the entire thing apart so we can find out what happened, which I'd rather not do, if it can yet safely be put to its original use of charging up my action camera, tablet, phone etc.

Once it's fully dried out I am sure it will be fine. They look like nice cells, would be a shame to throw them away.

Wow. What the devil was that radar system?

Because I'm using Sennheiser HDR-130 RF headphones via the mixing console, the amp keeps automatically switching itself off every hour, hindering the slow drying process. I'll give it a thorough inspection in a few days and will probably just use it, with slight nervousness and initially at least, some caution.

you wont get 3 3000mah plus cells in a 10 quid power bank and i bet if you capacity test them wont even be 1000mah

I think that famous high quality manufacturer of totally unfake capacity cells "Litokala" turned up in results, when I Googled "DBK INR2". And capacity seems to be much lower, than before it got rained on for three weeks (judging by it's charging of two action camera batteries and part charge of a tablet).

Get a pair of Quad II, they'll dry it out in no time.

Before they ban bikes and other small EV's , how about a ban on EV cars then all our lives might be safer. Afaics the rush to rip off follks with expensive EV's is not the answer to our transport needs, some cars don't even need to be in use to be dangerous.

So we carry on using i.c. vehicles and destroy the planet as quickly as possible?

 

And how are we to get deliveries without vans, increasingly switching to electric? Buses and Trucks too for urban use.

 

We've created a world where we have to carry on using buses, trucks, vans and cars indefinitely unless we totally redesign and replace everything by going back to a former age of localisation of all supplies in a simpler and less sophisticated world.

 

That will take at least the two centuries it took to create the mess we are in.

 

Meanwhile, electric vehicles are a major part of the solution. If you don't believe me ask the railways. Worldwide they abandoned i.c engines long ago.

 

As for e-car fires, hysterical reporting is not the answer. Governments just need to get a grip of the irresponsible manufacturers like Tesla who use very high capacity cyclindrical cells like 21700 and 18650 in pack formations of several thousands to be able to claim very long ranges combined with very high performance.

 

That is well known to be very risky and totally unnecessary. One can buy sensible e-cars with sufficient range and moderate performance which are totally free of traction battery fire risk. They use a few hundred physically large but lower density flat cells in a low stress charging and performing environment.

 

The one I bought almost five years ago (and which is still available) I'll still be using on the original battery in another five years or even ten years time if I am still alive. That won't be going up in flames thanks to using cells designed exclusively for the car job and not those that e-bikes and laptops use which have to be high density and small, so often being stressed and thus more vulnerable to failure.

I've been searching ebay for a good deal on a pair of Quad 405s for years - trouble is being so old, they need maintenance, and many of my local hi-fi repair shops have closed down.

An Opel Zafira (petrol I think?) went on fire in Ireland a few years ago and almost burnt down down a whole shopping center. It did 30 million euro damage but no one died. I suppose all fuel carrying vehicles, whether the fuel is electrons or oil carry some risk.

"It’s not all rosy, though, as any water contamination of the materials can lead to hydrogen sulfide production. This is a gas that is both poisonous and highly flammable. "

Too big for EVs:

A 12 hour static shot of a slow burning lithium fire at the end of movie care chases of the future, will look very boring. Hydrogen tanks less so, or maybe we'll see ball lightning when supercapacitors discharge?

 

Perhaps fireproof vacuum vaults will be built under all homes and workplaces, for EV batteries to be lowered into for storage?

EVs are moving to LiFePO4 technology, which is much less of a fire risk.

Maybe they got splashed by a salty wave while travelling along a coast road?

Off topic [mention=33660]guerney[/mention]. Don't the Chinese make (pretty good, no compromise) copies, as they also do with Naim and other amp classics - even down to the case cosmetics?

 

What you really want is a pair of exposure XVI's - same 100w high current approach and as rare as hens teeth. I bought a new pair, thrashed the nuts off them for ten years, and then sold them on for more than I originally paid.

 

Will there ever be e-bike classics that make it to collectible/appreciating investment status?

How much heavier are LiFePO4 ebike batteries? If bans are due to increased insurance coverage costs, from my point of view it'd be well worth looking into buying or making one.

Fortunately for my uses (production, a little composition), I only need average sounding speakers and amps for testing, but fantastic quality neutral headphones and studio monitor speakers... but for pleasure, I like the character of certain old amps.

Yes, good point, I really should take the plunge and nab a clone of something epic.

This is my ultimate aim of my Dahon build

So we carry on using i.c. vehicles and destroy the planet as quickly as possible?

I saw a graph the other day that suggested that 42% of the worlds electricity is still being generated by coal. If that is the case, 42% of the energy you're chucking into your EV is still heavily polluting our planet, it's just not polluting your own back garden.

 

I certainly do invest in renewables (turbines and solar), but everyone changing to EV's is just tinkering at the peripheries. There are far bigger, more important pollutant issues to address first IMHO.

 

...but fantastic quality neutral headphones

Try Stax electrostatic "earspeakers". They're sublime (and reassuringly expensive).
