I bought these a few months ago to build my own Vegabond comparable battery pack. I built mine to be twice as powerful (meaning faster recycle times) and last just as long. The Vegabond II uses the same brand but 150w. This is a Samlex 300w. The battery is 17ah. I paid $200+ for all of the parts and will sell it for $175 because it was never used in the field, just tested indoors. I ran my B800 for hours and it never slowed. I honestly don't know how many pops it can do but I couldn't run the battery down in.
I also have a 12v 3ah SLA smart charger. 3 Stages including Fast, Continue, and Float. $20. Not included in above price.
I have the original packaging and manuals. It is currently assembled in it's own protective case but I will not be including the case. If anyone has any questions about it let me know. Don't post because you can get such and such cheaper. Will only split unless both items are paid for before I ship either. You pay shipping. Prices not negotiable.
Not actual pictures of what I have but the same product:
