I will say the major advantages of lithium are that you can drain them lower than the 50% recommendation for lead acid and they are WAAAY lighter. For example I can get four 100Ah sealed lead acid batteries at 12v. That’ll come to 4.8kW but only 2.4kW usable, comparable to this. Those batteries weigh 80lbs each so…
