Jump starting a CC electric cart

Ok, So my friend-girl has a later model club car precident.
Somehow the pack discharged below the nominal voltage to kick in the charger (which I do not know the threshold). I tested the pack today and it is well below 48v. I believe it was 35v.
I also have a 48v CC precident. All the chargers work on my cart which has a healthy battery pack.
When I had an ezgo I could bring them up in pairs with a 12v charger. I need to trick the charger so it will charge her battery pack.
Can I use jumper cables from my first + terminal to her first + doing the same with the final battery - terminals? Then plug charger in to her cart? I want the charger to see enough voltage to kick in at which point I would disconnect the jumper cables.
I realize her pack my be damaged. However, the batteries are pretty new, look great, cables are good... I would like to charge this pack at time or two and see if it will come back at all.

Lastly, if anyone can tell me another method or trick to fool the charger to cycle I would greatly appreciate it.
Thanks in advance.

Worst case I'll load it up and take it to tahoedog but I'd like to at least see what I can get the pack to do.
