Looks interesting, great price unless shipping cost is high. I emailed the distributor in Arizona a couple questions and he expects stock in 2 weeks, warranty will be with SOK, hopefully won't have to send/receive from China.
The charge rating is 50 amps/battery so charging might be slower than Battleborns or others, but with solar or alternator charging could work out just as well. Only time it could be an issue is with inverter charging but you can set the max charging amp on inverter. It would just take longer for a full charge. Not a problem if plugged in but if on generator would mean longer generator run time. Depends on your usage. If the BMS limits the incoming charging amps that could protect your alternator from overworking.
7 year warranty is good especially if a USA distributor can handle any exchanges. If they have to come from China that could be a problem with time and shipping costs. I like the open case design, makes it user serviceable if needed.
The case is metal, nice for heat dissipation. I looked into them but in Canada they are less readily available and more expensive.
Charging directly off the generator's 12V outlet will be ridiculously slow (as it will with any type of battery), you will need a charger for more amps.
BMS doesn't limit the charging current, it only cuts off when battery overheats. With low internal resistance it will try to suck out maximum possible current from the alternator and could overload and burn it. Li batteries need a proper DC-DC charger between the alternator and battery, Renogy make 20A and 40A models - they are a so-so brand, maybe there are better makers out there.
