We've been sourcing these CATL 3.2V 280Ah cells for about six months now, and they consistently hit the 280Ah nominal capacity right on the nose, which matters when you're stacking them for a 48V bank — one weak cell throws off the whole string.
These are genuine Grade A+, meaning they're matched on internal resistance and voltge from the factory, and the 1C discharge rate lets you pull 280A continuous without thermal issues, though for longevity most buyers stay under 0.5C.
Each cell ships at roughly 3.2V with a laser-welded M6 stud terminal, and the copper-nickel bus bars (90x20x2mm) are included, so you don't need to source those seprately. They weigh 5.3kg each, so plan your forklift or dolly.
The cycle life is rated at 2000 cycles to 80% capacity retention, but we've seen them go past 3000 in solar storage setups where discharge isn't aggressive. 0.5C charge rate is the sweet spot for balancing speed and cell health.
Not ideal for high-rate pulsed loads above 1C — these are energy cells, not power cells, so don't plan on starting an engine with them. Tempearture range is -20°C to 60°C for operation, but we usually tell customers to stay above -10°C for charging.
CE, UN38.3, and MSDS are on file, and we've had zero voltage drift issues across the first 500 cycles in our test rack. Warranty is 1 year from shipment (usually 2-4 weeks lead time on bulk orders), and the MOQ is 4 cells for the discounted price.
For the bulk discount, we typically require a minimum order of 50 units. Orders above that qualify for tiered pricing, so reach out with your quantity for a custom quote.
Yes, we include copies of the CE, UN38.3, and MSDS certifications with every order. They’re sent as part of the shipping documents.
Yes, they’re rated for a 1C continuous discharge (280A). The operating temp range is -20°C to 60°C, but for best cycle life keep it below 45°C during heavy use.
Each cell comes with a copper nickel plated bus bar, 90×20×2mm. They’re ready to bolt on with the M6 threaded studs—no extra hardware needed.
Store them at -20°C to 45°C, ideally around 50% state of charge in a dry place. At proper storage conditions, they’ll hold capacity well for over a year without significant degradation.
