All SoGens (good acro, btw) have "sex appeal", and adding wheels is even sexier ... however, these are what I consider to be the numerous "strikes" against this particular unit, at this time:
1. AGM instead of LFP ... that sounds like the product was rushed to market, and at the very least, you want to wait until the 2.0 model, where they might fix this design flaw.
2. 1-year warranty ... you can't pay $3k for an item with only this short of a warranty period. 1-year or less warranties are for disposable things, like coffee pots, where you don't care if it dies after 6 months, because you only paid $100 for it. $3k needs a 3-year warranty or better. Look at SOK batteries from CurrentConnected, with upwards of a 10-yr warranty (IIRC), on a roughly $1500 item.
3. find a tear-down vid ... or wait for one. there's much going on inside that needs pondering.
Z. Will P. is right, of course ... you can build something much better, if there is any kind of DIY bone in your body. If you don't have such tendencies, that is where the sex appeal of these things comes into play, and if money is burning a hole in your pocket, then by all means buy two of them (one to use, one as a spare).
Aside from these, it appears to have a pretty good feature list. There were some support pages & docs on their website, but nothing of technical substance. Nothing about "error codes" or troubleshooting ... a bad sign. Once something gets in the hundreds of pounds range, you have to consider how it's getting RMA'd (freight shipping only?) ... there are no local service centers.
Hope this helps ...
