At 10Ah and 30Wh per cell, this is roughly \u003cstrong\u003e8× the capacity\u003c\/strong\u003e of our 18650 sodium-ion cell in a single robust package — ideal for EV conversions, e-bikes, car jump starters, marine\/RV packs, and stationary solar storage.\u003c\/p\u003e\n\u003cp\u003eLike all sodium-ion chemistry, the 32140 delivers outstanding cold-temperature performance, operates safely with no thermal runaway risk comparable to lithium cobalt chemistries, and is built from abundant, responsibly sourced sodium — making it a genuinely sustainable choice. The layered oxide cathode gives it a higher working voltage and energy density than polyanion (NFPP) or Prussian blue sodium chemistries, while the large 32mm diameter format allows for very low internal resistance (≤3mΩ AC) and high peak discharge rates up to 10C continuous.\u003c\/p\u003e\n\u003cp\u003eThese cells have passed \u003cstrong\u003eUN38.3\u003c\/strong\u003e safety testing and are shipping-certified.
