Drained Battery, Any jumpstart tips??

[Yann]

I have jump started a buddies JL with the two batteries with no issue. Hooked the Lithium jump start to the main battery and had success.
Why does this not work for everyone that leaves their lights on and kills their battery?

What kind of JL? 3.6L ESS? what brand of battery pack you used? happen in cold winter?

I have a NOCO jump starter. Killed my 2018 3.6 with two batteries. Hooked the red to red and black to ground bracket and it jumped like any other car. I did not disconnect anything.

What size is your Noco? My gb40 1000amp won’t jump mine. Wouldn’t boost off an F-150 either. I disconnected the ess at the main batt, charged the main for 5 hours then it started without the ess batt.

I have taken aux out of the equation with jumperless solution. One battery...easy jump start.
