What to choose for your build

  • Portable/DIY packs (12–24V): 32140 or 46145 for compact builds and cold-weather performance.
  • Home/solar storage (24–48V): Prism100 for modular 24/48V banks; Prism210 for high-capacity racks.
  • Cold climates: All models deliver usable capacity down to -20°C to -40°C (with C-rate limits).

Sodium-ion vs LiFePO4 (LFP) at a glance

  • Cold weather: Sodium-ion maintains capacity at sub-zero temps with fewer heater requirements than LFP.
  • Safety: Robust abuse test outcomes in vendor specs; wide operating window.
  • Cycle life: ≥3,000–4,000 cycles at 100% DoC (daily cycling friendly).
  • Voltage planning: 8S ≈ 24V and 16S ≈ 48V stacks match common inverters/BMS.
