Using older strobes with a battery pack

I have a set of Interfit Stellar 300 (mk1), which came out circa 2005 or so. I want to use them with a battery pack but I have been receiving a lot of confusing information.

First off, I understand the reason this model was discontinued and Interfit released the newer Stellar Xtreme range so that it could be used with a battery. This seems to imply that the older strobe, the one that I own, is not compatible.

I searched the web for information but "Stellar Interfit" returns information that pertains to the newer models rather than the one that I own.

I asked Interfit, they confirm the Stellar Battery does not work on my model, and they do not recommend using it with a battery. It's not clear to me that it's because it doesn't work, or they just don't support use with a 3rd party battery pack.

Anyone test a Vagabond II or a Vagabond Mini with this strobe?

You can use a battery pack but can the one they offer provide sufficient power output for that specific unit?

The problem is going to be the modeling lamp sucking to much constant power which can always be removed while on battery. Interfit of course would rather sell you new equipment as would Paul Buff, Elinchrom and all the rest of the lighting companies. You can also build a battery pack that meets the specs of your stuff to power the modeling lamp or the Vagabond should work fine if you just want to keep it simple. Might not get the same length of power that an AB user gets and you may need to remove or disable the modeling light but Vagabond will work. I would actually call AB and ask them how you should use their product as they should have the answers you seek.
