Small body, serious stamina—plug-and-play 48V storage that scales in parallel and keeps cool under pressure.
Compliance Standards: UN 38.3, UN 3551, UN3552, IEC 61000, IEC 62619, IEC 62477,IEC 60529,GB/T 36276
Designed for both B2B operators and C‑side facility teams.
parallel-ready design supports multi-pack operation for easy capacity scaling.
works across -40°C to 60°C (discharge); charging -10°C to 50°C—reliable from cold mornings to hot equipment rooms.
sodium-ion chemistry is engineered for high thermal stability; in thermal-runaway scenarios it’s designed not to ignite or explode at the cell level.
potting (encapsulation) process bonds cells to the housing for excellent anti-vibration performance in mobile or outdoor installs.
sodium-ion cells can safely discharge to 0V, helping with logistics, deep-discharge recovery and long-haul shipping.
sodium-ion is more stable and less demanding on storage conditions; unit ships at 0% SoC in cardboard packaging to simplify warehousing.
widely available raw materials for sodium-ion cells provide greater price-reduction potential versus many lithium chemistries.
~2.43 kWh per module (48.5 V × 50 Ah); add modules to build the bank you need.
50 A continuous charge/discharge with matching max continuous 50 A rating for steady performance.
fits common 48V ESS/UPS/telecom architectures for straightforward integration.
