Will this easily jump start a dead Mach-E? 12v battery boost from NOCO

[kltye]

Hmmm... I think I'm starting to better understand the dramatic difference here between the 12V battery on the EV (Mach-E) versus the traditional gasoline ICE car. While a small power bank like the NOCO or Gooloo can deliver a short burst 10-20s to get an ICE engine to turnover and started which is all you need, (like shown in the nice review of these by Project Farm, thx Mach-Lee), since after that the ICE engine runs and becomes the power plant for the car whenever running and the 12V battery can remain dead after the gas engine is started up.

It is somewhat different for the Mach-E. You need continuous battery power from the 12V battery while the vehicle is running. Thus none of these 10-20s pulses from a power bank (e.g NOCO and Gooloo) would work to resurrect the 12V battery enough for the Mach-E, unless they could quickly re-charge the built-in battery in 10-20s but that is not going to happen. The power pack would definitely let you open the frunk, and maybe if attached to jump the 12V battery would help boot the car for a few seconds, at most get doors open, but not even long enough to get the car into neutral to tow, or definitely not help solve the dead 12V battery.

Am I overstating the *lack* of utility of the NOCO or GooLoo in this circumstance with the Mach-E?

I've done measurements from the OBD port about how many watts the car requires to run its electronics, and I believe the peak was around 400 watts (no exterior lights or HVAC, of course). If you're quick enough (and I don't see why you wouldn't be), that's enough to engage tow mode. That's assuming your LVB is completely dead; it usually isn't, and with the aid of a jump pack, I'm pretty sure you could squeeze a few more watt-hours out of it (due to less internal resistance from less load being put on it).

I'll point out what should be obvious.

Most of the time, you engage Tow Mode to be towed. By a tow truck. That truck has full capability to provide the 12V need to open the vehicle by popping the frunk, connecting to the 12v battery, and providing the power to charge the battery enough to put it in tow mode.

There is no need for an independent power supply of any type unless you plan on putting it in tow mode to tow it yourself.

Ha, this is a very wise comment. Thanks for pointing that out RickMachE. So true.

I guess the ability to get into your vehicle is helpful if stranded somewhere for an hour waiting for the tow truck. And the ability to do stuff, like open the frunk would make you feel better. If you never cut holes where the jump points are, well you can slowly undo the covers in advance maybe?

Dumb question (more dumb than before lol): Is the best 12V battery jump starter for the Mach-E another brand new fully charged FoMoCo Mach-E 12V battery? (in a little case with a handle perhaps ha!).

Let's assume it was.

1) Where would you store a battery?

2) You can't get them. Go try and buy one.

3) They are like $150 or more.

It should be more then enough to wake the vehicle up until the dc/dc charger kicks on. The jump clamps time out after 60sec, after that you need to power cycle the pack. That said it’s probably not worth it. If you leave these jump packs fully charged they only last a few years. Pretty much a waste of money.

I took a photo of a power pack we use at work, to “jump” our old forklift. I don’t see why this wouldn’t at least get you into tow mode.

While I understand people thinking about how to deal with situations, at some point you have to stop and enjoy the vehicle.

I see people buying a spare tire, jack, and loading the rear floor with it (what happens in an accident)? Installing a bigger battery. And so forth.

I put my jumpers in the frunk.
I modified the panel to access the battery easier, mostly so that the dealership wouldn't keep prying the panels off.

Relax, and enjoy the car.

Will the NOCO Boost X with 1250 amps work easily jump starting a dead Mach-E? I hear the NOCO booster Jump Starters are good and particularly for the Mach-E because they have the little manual override button which can first get you into the frunk via the wires in the front bumper, even though the jumper is not sensing attachment to a battery. BUT which size would you buy? I also heard while the Mach-E 12V battery is small, jumping it works best with something designed for a BIG truck.

COSTCO sells those for 50 dollars. I keep one in the Mach E. Not just for me though, I have found I've used it 100% for helping others. It would work for the Mach E if needed. It can also charge stuff if you are stranded, such as a phone.

Those little devices you carry specifically to pop the front trunk so you can access the battery only. If this happens at home take the battery out and slow charge it or buy a new one.

so where do you propose storing the power pack?

They are not that little, and if 12v is dead you cannot get into Frunk or rear cargo. You are going to rely on another vehicle on the outside.... so if THEY have regular jumpers you are all set for both frunk-popping and quick-charge of 12v to get you home or to Dealer's.

First, thanks for your reassuring comments here at the Forum to not obsess and enjoy the car, that actually DOES greatly make me/others feel like “Right yep exactly, dude is right” but I like at least thinking about creative solutions even if not super necessary. And love learning stuff from others here like just happened today regarding 12V battery roles in ICE vs EV.

So, very true, but just everyone(?) humor me a little longer if possible, I’m curious, maybe someone else is too, just for long road trips, BUT my answers to your questions may be: Rock Auto has had the OEM battery in stock for a month, battery in a tiny secret agent briefcase, the power boost devices are up to $150 anyway. And if old battery dies eventually need new one to replace it.

SO … Here’s the dumbest idea I will submit: Your car is dead, you have access to another new fully charged FoMoCo Mach-E battery. So you pull out the wires from the bumper’s door (kinda a secret agent panel right), touch them to the FoMoCo battery briefcase terminals and the Frunk does the clunk clunk clunk opening, then you have jumper cables already stashed in the frunk (I already hear 007 music) put battery briefcase in said frunk, connect cables via drilled jump points to cars LVB, and Bob’s your uncle?

so..... you want to buy an extra battery, carry it around in your Frunk for 5 years, go the the trouble of pulling your Frunk to run wires to the bumper port, ... and likely never use any of it?

Well when you say it aloud it sounds dumb.... actually I am too lazy to pre-run the cables, rather just stash them in the frunk, but already have cut those 2" access holes in the cover above the jump points, which IMO should already be done by Ford. The Mach-E battery is quite small. I'll stop posting now since I think I'm the only person interested in this idea. Everyone else is sane..
