Not sure what kind of rig can handle 500 or more pounds so easily as one poster believes. We have just about 9.8 kW hours of LFP which gives about 7.9 kW hrs of usable energy. The battery suite is 260 pounds and equivalent PbS would weigh about 700 to 800 pounds and four times or so the volume. The battery suite, battery chargers (if we ever need to use line power or generator and we have done once in close to 13 months), controllers, inverter etc fit in the forward compartment Open Range has for a large Onan generator. We would be over pin weight with PbS. The system has worked extremely well for us in a light weight fifth wheel. There are ongoing discussions on LFP for residence and trailer/caravan on Solar Forums. The Aussies are going full bore on this
