CATL's largest 587 Ah LFP storage cell goes on direct online sale at $65 per kWh

The 587 Ah LFP cell, CATL's largest energy-storage offering, has moved from out-of-stock status to open sale on the company's e-commerce platform, CATL Mall. Pricing is set at 435 yuan (about $65) per kWh, and each order must include at least 324 cells — three boxes — for a minimum spend of roughly 265,000 yuan, nearly $40,000, representing 608 kWh of total energy, about what twenty entry-level BYD Seagulls carry in battery packs. Purchases ship within three to five days and come with a five-year warranty at no extra charge.

Stationary storage is the cell's only intended role: its 0.5C rating rules out use in electric vehicles and other high-power applications, unlike the 1C-rated 280 Ah and 314 Ah units that were among the first products listed on the mall. CATL specifies 8,000 cycles to 70% state of health at 25°C, permits discharging between -25°C and 60°C, and allows charging only above freezing. Each cell holds 1.88 kWh, weighs around 10.6 kg, measures roughly 310 x 222 x 73 mm, and achieves an energy density of 379 Wh/L.

Deliveries to large-scale customers began in late 2025, and the online listing now extends access to smaller system integrators with limited purchasing power. More than 1,800 companies have registered on CATL Mall since its launch, though a valid Chinese business license remains mandatory — international buyers must either route orders through a mainland broker or set up a subsidiary inside China.

The asking price carries a premium over the domestic market: industry outlet ess-news.com reports that rising material costs and strong demand pushed the April 2026 averages for 280 Ah and 314 Ah cells to roughly $55 and $59 per kWh respectively. Even so, China EV DataTracker credits CATL with 31.4 GWh of installed capacity and a 42.9% domestic share in July 2026, suggesting plenty of buyers still see it as a "top-shelf product" worth paying extra for.
