Lithium jump packs

Do you think the new energiser lithium jump packs that are being sold for jump starting cars would be a cheaper alternative to the deben lithium lamping battery? Could they be used for lamping?

 

Aldi are selling them for £49.99 way cheaper than anywhere else.

Jump packs are a different type of battery designed for high output for a short time in a short cycle,where as your leisure batteries are low draw deep cycle battery.

 

That's lead acid batteries ,

Lipo batteries don't have a memory .They are very good but need extra circuitry , They don't like being mishandled mechanically or electrically and readily catch fire .

You hear of the odd one catching fire,but seriously,considering how many are around in phones,tools,torches ,cars of various sizes, and a multitude of other applications.

So to say they 'readily' catch fire is somewhat inaccurate .

"SAMSUNG GALAXY S7 " -- expensive hand warmer !!

 

I said they just need EXTRA protection circuitry .

 

You cannot just buy the basic battery and use them you would with old style batteries.

 

There is a reason bare batteries are banned on passenger aircraft.

Galaxy NOTE 7 .

Definitely not the first phone to catch fire,Ill give you that,but the millions that were supplied,maybe a 100 actually caught fire,none exploded,as reported in the press.

Im not disagreeing with you per se,but people get a bit carried away with media hype regarding lithium batteries.

The FAA have controls in place regarding lithium batteries ,yet most planes have them on board to run their electrical systems/backups.

The usual reason they fail is because the separaters break down,which 'sometimes ' causes smouldering/fire.

 

The battery pack in question ,which Im going to have a look at/buy shortly will most probably have a 12 v outlet ,like most other car jump packs have,so should be safe for the OP to use as a lamp battery.

Had a look at one of these yesterday, I wont be buying one anytime soon,certainly not for £50.

First of all they are somewhat smaller than I thought it would be,it could easily fit in your pocket.

They weigh very little,and only push out about 200 amps,so thats not going to start any diesels.

Looked like a glorified phone power bar to me.

Or even this one

A few liberties taken with the facts there .

 

50Ah I think NOT , 5Ah probably

 

The blue connector is an EC5 rated for 120A max

 

Exactly , Id have to see one of these start a car without melting.

But as a back up for NV or lamp ,definitely a use for such things.

They are not built to start cars they are designed to transfer their charge to the cars battery to give I short term boost

 

Regarding the talk about lithium and aircraft, at least two brand new Dreamliner's had massive damage whilst on the ground when there lithium batteries caught fire

They are advertised as 'jump packs' so people will use them as such,whatever the result!

Massive to me is aircraft write off,which in this case was no where near.

The media loved it, the Dreamliners competitors more so.

 

The point I was trying to make was,generally speaking ,lithium batteries are safe,there are billions in use (If you doubt that,think about how many YOU have,I stopped at 50)

The thing is when some do go wrong,the media ,makes a big song and dance of it,do you not find that strange ?

When a tanker goes up and takes out a small town, no one starts saying petrol is really dangerous.

I think there are far more dangerous things in the world besides Lithium batteries.

Have a look at lithium motorcycle batteries, I have just stuck one on my 4 stroke bike and it feels like an empty box it's that light,and cranks up really well. You can pick how many ah you want then. Ebay is a good place to check prices.

'motobat' with the yellow casings. Last ages, powerful little batteries that are cheap to buy and light enough aswell :)

These type of comparisons are extremely misleading.

6 litre V8 petrol engines dont really take a lot of cranking,try using this same booster on a 2.0l diesel with a totally flat battery and see what happens.

The one above is over £100 and you can can go up to £500 on lithium booster tech.

Im not saying they are useless,but ,for your money,lead acid tech is still better,more powerful in cold cranking amps.

The ones for £30 -40 are a big power bar,better suited for charging phones and laptops.

My energiser jump pack has got me out of a hole on many occasions starting cars with flat batteries.

Granted it did fail to start a vw transporter with a totally dead battery, but all other things with a battery that wouldn't quite turn over it has managed to get going.

It's light enough to stick in my backpack and cart everywhere with me. Just need to remember to charge after each use.
