Any suggestions for lithium ion battery packs for jumping off automobiles with dead batteries?
I use a 3.3Ah 4s Lipo pack from my RC hobby whenever I need to jump a vehicle.
I’m also interested in knowing what’s what for jump starting auto batteries. ??

Subscribed. I’ve been considering getting one of these myself, so hopefully there’s some feedback.
Like Cereal_killer, I use old hobby Lipo packs and a cable I made up with $1 clips from AE:
It has saved me a couple of times.
I imagine a charger for that battery pack is required could you post the whole kit ?
I would like to compare the hobby R/C pack or the dedicated jump starter.
I use a few different chargers, mainly an old IMAX B6 and a ISDT Q6 .
I guess if its just for the one purpose you could get a very cheap balance charger, something like THIS maybe.
NOCO geniusBoost +.
If you are looking for one to use for a business, below is what we currently use. its quite a bit lighter then our old ones and I think they can jump start 4-5 skid steers off one charge but would need to verify that.

I can only suggest buying a real quality one like the linkedc or go with simple 3S battery pack at around 4-5Ah thats rated at least 20 or 30C
the cheap ones are not safe, many reports of blown lithium batteries no safety features ect.
The most important do not store the lithium pack in winter in the car it needs to be at least 10°C warm to deliver enough current
I don’t think that would even move the starter on my V8 F-150
Man, at the prices of these things ($279 as linked above) it’s cheaper to call a wrecker on my road side assistance insurance for a jump…LOL 
Surely there’s a reasonable deal to get ones butt out of a jam for a modest price somewhere? I’ve seen em on sale at WallyWorld for @ $40… and at the time, I didn’t know if any good.
the cheapest is having a jump starter bridge and ask your neighbor or some stranger driving by to give you the juice from his battery and light machine
I don’t know, I drive an old Civic, it works for that and I’ve used it on a van.
I used a 4s pack of less capacity (3300mAh) and had no problems with my 5.4 explorer, even with my duramax.
Take into consideration the vehicles charging system runs about 14v so a fully charged 4s pack is still a few volts above that. Proceed with caution…
I’ve never had a problem with my F150 since the interior lights will auto shut off after a while. But my Wife’s, Honda Pilot was a royal pain in the ass. Can’t tell you how many times I had to jump start that when one of the kids left a light on in the back seat somewhere. One of these portable jump starters would have been nice for sure.
Time for some LED lights in there.
The new Ford Edge is pretty much all LED as far as I know, and it auto shuts off the lights too.!
Buy these from the source; beware of the fakes. Have had good luck with them and so have friends over the years: https://shop.antigravitybatteries.com/products/micro-starts/xp-10/
