This is a 48V-class sodium-ion storage battery rated 100Ah, about 4.8 kWh, sold under model JM-W-48V100AH. Sodium-ion chemistry is the draw: it holds up better than lithium in cold and is less exposed to lithium supply swings, but it stores less energy per pound, so the pack is heavier for the same capacity. It suits off-grid and backup setups where weight does not matter and cold-weather charging does. Against lithium iron phosphate packs of the same capacity, expect similar usable energy but a shorter track record and fewer inverter integrations.
