The JMBatteries 48V 100Ah is a sodium-ion energy storage battery rated at 48V nominal, roughly 4.8 kWh, with a 24V–62.4V operating window and CAN, RS232 and RS485 communications. Sodium-ion chemistry is the draw: it holds up better than lithium in cold and is marketed as safer and cheaper to build, and JMBatteries rates it at 6,000 cycles over 10 years. It weighs 132.5 kg and can be wall-mounted, stacked or moved, with enclosure ratings listed from IP54 to IP65. Its only recorded price is $1,437 on October 31, 2026, so there is no range to compare against yet.

No owner reviews or independent tests of this specific model were found. Sodium-ion storage in general draws praise for cold-weather performance and safety, and criticism for lower energy density and thinner inverter support than LFP.
