24 volt jump starter

[Mr Tibbs]

I was wondering if anyone carries a 24 volt jump starter pack with them while camping or on their expedition travels? Normally I don't worry about it, but now that I have a 24 volt vehicle I can't get a jump start from any old Joe with a vehicle!

So, I have been doing a little bit of shopping on Amazon and am looking at a couple of options, but I would like some input before purchasing. I am looking at these two jump starters:

ATD Tools 5933 12/24V Jump Start and Truck AC ES8000 1500 Peak Amp 24V Jump Starter.

Any thoughts or opinions?

I have been jumped by 12 volt vehicles several times. I put the cables on a single battery of the 24v pair, usually the low side one, since it's often the weaker one.
Probably wouldn't work for profoundly dead batteries, but works great when you've got some charge left, but not enough to glow and turn the starter over.
Don't have an opinion on a jump pack - my solution to killing batteries was to put a buzzer on my headlights. Though, I can see how you might want a bit of security if you're doing some heavy power usage on an expedition, and you're by yourself.

If you have two sets of jumper cables (and not the cheapest ones) you can ask two cars and in my HJ the left side goes first so if I connect that one to 12v it starts oke, the glowing is really a high impact drain and starting after that is just a killer.

For more info on the battery I use three volt meters: left side, total, right side battery:
engine off, few hours after driving:

Agree with "Freewheel." I've been jumped several times by 12v vehicles. No problem. Just hook up to one of your batteries. Usiually I know which of my two are weak and jump to only that one.

hj60 -- love that dash voltage display!

I think for the price of either of those jump packs, I'd install a third battery for reserve. But as mentioned, 2 sets of jumper cables and two jump vehicles will always work, or usually a 12v jump on one battery will be enough.

I have to agree I like that voltage display as well very nice.......

HJ60 how do you get a reading from your left battery I have similar meters but I get 12+ on my right side but 24+ on the left how do you get a read on the left without disconnecting the connecting battery cable.

Hi guys, thanks, it is a very cheap thing to make yourself.

EDIT: after 5 years still no problem and never failed, but they use power that could drain the battery in a few weeks, I use charger so no problem and when on holiday never had a problem with these using to much current or something when parked.

But the right (high side, charging input, PLUS, +) always seems a bit lower than the Min,- side to chassis, also direct after switching batteries, and testing them when disconnected also sometimes gives no difference while meter shoes 0.1 v difference, but accurate enough for me.

Maybe consider using equal length/size/quality cables to remove resistance?

My wife made the fitting row with a dremel from old plastic box, painted it black

=1500 rpm = 14 Volt
>2000 rpm = 14.3 Volt

The price is not the most important, the safty and performance should be considered.

I’ve been using a small jump pack that I originally got for my fj62. I just attach it to whichever battery is lowest and that has seemed to work. One time I had to use jumper cables to one battery and the jump pack on the other to get started. I’m considering just buying a 2nd jump pack so I can hit both batteries. I’ve been using the GB40 but might go with the GB70 for my 2nd.

Going to piggy back on this thread to ask if anyone uses this jump pack? If so, what are your thoughts?
