Sodium-Ion Is Ready for DIY: What the New Chemistry Means for Your Next Home Battery Build
By TrickyFrick·1 reply·15 views
CATL's Naxtra cells hit 175 Wh/kg with 10,000+ cycle ratings and 93% capacity retention at −30°C. 210Ah sodium-ion prismatic cells are available today for under $70/kWh. Here's the honest comparison against LFP — where Na-ion wins, where it doesn't, and who should actually consider switching.

Has anyone actually sourced the 210Ah sodium-ion prismatic cells in the US yet? Everything I'm seeing ships from China with 6-8 week lead times and the import tariff situation makes the sub-$70/kWh number a lot murkier by the time it clears customs. I'm not saying it's not worth it — the cycle life argument alone is compelling if those 10,000-cycle claims hold up in real-world conditions — but I'd pump the brakes on calling it a clear win over EVE LF280K until we see some independent long-term discharge data. Would love to be wrong here. What are people actually paying landed?
