I am close to pulling the trigger on a pair of Einsteins and am also considering getting the Vagabond mini battery pack with them.
I've reviewed some DIY threads on making your own battery pack, as well as looked at posts about the Vagabond mini, and one thing I noticed is that some of the DIYers posted later that their systems crapped out fairly quickly for electronic reasons I don't really understand. Needed a different inverter, inverter was not rated for the specific use, that sort of thing.
One post from quite a while ago about the Vagabond mini said it, too, became inoperable fairly quickly, but the Paul C. Buff customer service was fantastic and they replaced it right away. It was an old post though and the Vagabond has been around a while now, so may be more reliable.
My question is why are battery packs (apparently) so fragile? I doubt I could put together a DIY unit for less money, but might I get more robust components? Although I don't understand the electronics, I can hook stuff up using PowerPoles and have done so for some low-tech ham radio stuff in the past.
What is the consensus on the Vagabond minis recently? Should I
1. Get a Vagabond mini
2. Get a more expensive battery pack from another maker
3. Put together one on my own (I will need specific component recommendations)
Thanks!
