These seem quite popular today.   [....look much easier than hooking up jumper leads, onto another vehicle]

Any advice on what to look for when buying ?

Some available, in Australia, on eBay, from around $60 now.



I will need to jump start a diesel ute.

Do you really need to jump start that often it's a pain? You could go dual batteries if you go off road. Once one is discharged, you know exactly what you have in reserve.

Is it this one?

I would just get a set of jumper leads, what happens if battery bank doesn't have enough charge because it has been sitting unused for a while?

If it needs frequent jump starting then battery is stuffed or didn't have enough cold cranking amps.

Deep discharges ( less than 50% charge) stuff Lead Acid batteries resulting in a much shorter life.

The battery in my Torana is over 20 years old still going strong because I drive it at least once a fortnight.

A friend in town has a Power Bank.....

1/ You can charge the power bank [off mains] overnight [if it is low].
They all seem to have an LCD display, which will show % of charge - just keep an eye on the charge level.
I live out of town, and my close neighbours are all getting to be old and infirm, so would rather not bother them for a jump start using cables [to another vehicle].

2/ I know to replace my battery when it is stuffed.   ...it is just that through a cold winter, an early morning start, can test an 'old' battery.
If my battery fails to start my diesel, i just need to start my ute to get into town to buy a new battery.

4/ My last ute battery lasted for 11 years [with frequent water level checks].
My current battery is about 7 yrs old.
I drive into town [charge my battery], at least a couple of times a week.




Reply #7,
miketrees, Thanks for that post.
Sounds good!
It encourages me.



Reply #2,
Setanta,
"Do you really need to jump start that often it's a pain?"
No.    I can't remember the last time i needed a cable jump start.

A friend in town has a two battery setup in his diesel ute.
But it looks like a lot of faffing about [cabling, and switching gear, and all].
That friend, is the one with a Power Bank now [as well].

If a Power Bank will help start my ute on a very cold morning, that will be sufficient.
I just need to start the ute, so i can get to town to replace the L/A battery.

The itech 900A has a 900 Amp peak.
the 1000A has a 1000Amp peak.
And now I see they have a 2000A with a 2000 Amp peak.

They are not only good for jump starting but can recharge mobile devices, run fridges etc.

They also recommend you discharge it every 3 months and recharge.

I discharge mine by running the camping fridge

Looks OK - buy it.
The only thing I don't like are the skinny red & black wires -
they don't look thick enough to pass 400 amps.

Your first link is dead.
You shouldn't have to modify them.
Yadda should just try it & see.

Get one with sealed lead acid batteries and it will start anything and last for ever and like a car battery can be recharged countless times without losing capacity.

Lithium batteries steadily die with each recharge.

One I have is a Booster Pac  ES5000  12v 1500 peak amps. I have had it for years. recharge with a small trickle charger. A bit heavy but a goody.

So why would EV's need a supercap?

lee wrote on Aug 20^th, 2019 at 1:40pm:


because capacitors are much more efficient than batteries at storing or supplying energy so they are ideal for huge current dumps such as acceleration and regeneration. Tesla will most likely use them as a buffer between the motor/generator and batteries

Sir lastnail wrote on Aug 20^th, 2019 at 9:56pm:


Yes they are. But you need a lot more of them as they are typically 2.7volt and low amperage.

Sir lastnail wrote on Aug 20^th, 2019 at 9:56pm:



Incredible. LostNail can see into the mind of Elon Musk, the man who would nuke Mars.

Sir lastnail wrote on Aug 20^th, 2019 at 10:35pm:



That's why you need a lot of the petal. In series for about 16 volt and in parallel to provide the amperage.

You really should do some reading before you make an even bigger fool of yourself.

Sir lastnail wrote on Aug 20^th, 2019 at 10:35pm:

Wow, just 6 supercapacitors and a $12 battery.

Could be an idea to watch the YT, lee. Just saying.

You have a YT channel?

google Power Bank Portable Car Jump Starter

But BH gets goose bumps if he uses Google!!!!!

Then perhaps you can annotate your posts?

Sorry, I don't follow Yadda either. I know nothing of the writing style.

Lithium battery car starters aren't much chop because the lithium batteries lose some capacity every time you recharge them.

And if you try to start something too big like a 600HP diesel then the lithium battery will overheat and could explode into a fiery inferno.

BH, on a first name basis ?

How is treatment for your Google Phobia going ?

On the drag strip one can meet 600HP diesel cars.

But BH you are just trying to go off on one of your tangential change the topic circular thingies.

LarfTillUFart is behaving just like Greeny. She is not the full quid.

Juliar has been pushed off the road. Juliar should not have been taken off the blocks. He evidently can only propel himself downhill.

Hand cranking noises coming from Juliar again. Followed by jacking noises and creaking.

Juliar's hand-cranking has started his engine but he is out of fuel.

It is good fun stirring up a decrepit failure like the silly old Greeny LarfTillUFart.   How does anyone end up like this ?

How do they breed sad creatures like LarfTillUFart ?

Obviously you drive an EV so when your batteries fail a jump start battery would be nowhere near big enough.

But more likely a 100% urban cowboy.
