The main thing to know is these aren't designed for high-drain continuous discharge application like some power tools demand, so if you're running a 40A+ motor controller you'll want a different cell chemistry or a parallel configuration, but for typical e-bike hubs and moderate tool use they're fine.
You're looking at 2000-3000mAh per cell with a nominal 3.7V, and the NCM cathode gives decent energy density for the size, roughly 18mm by 65mm, so they fit standard 18650 holders without any modification.
Cycle life is at least 500 cycles under normal conditions, which is pretty standard for this class, and operating temp range is -20°C to 68°C, so they'll handle cold storage but don't expect full capacty at the low end.
CE and UN38.3 and IEC62133 certifications are in place, which covers most shiping and safety requirment, and there's a one-year warranty, but we usually have stock so confirm lead time if you need more than 500 units or so.
Customiaztion is avaliable for voltage and capacity and even physical size if you're doing a custom pack, but the standard 3.7V 2600mAh is what most buyers go with for e-bikes, and the 5L drum or cell trays are easier to handle than loose cells.
Anyway, the spec sheet says 18×65mm, but what it actually measures is closer to 18.3mm on the diameter give or take 0.1mm, so check your holder tolerance before ordering if you're doing a tight fit.
Our MOQ for this model is 500 units, but we can negotiate for smaller trial orders if you're just getting started.
Standard lead time is 15-20 working days after order confirmation and deposit. Customized packs may take a bit longer.
Yes, we include all three certifications—CE, UN38.3, and IEC62133—with each shipment. We'll share the test reports and certificates upon request.
Store them in a cool, dry place between -20°C and 25°C. Ideally at around 50% charge to preserve cycle life. Avoid extreme heat or freezing.
Absolutely, we can adjust voltage, capacity, and even pack dimensions to fit your application. Just send us your specs, and we'll engineer a sample for testing.
