our company can adjust the cell dimnesions slightly beyond the 32*70mm standard if your enclosure needs a tighter fit — just send us the drawing and we'll quote tooling changes, usually 2-4 weeks lead time for a custom run.
The 5500mAh nominal capacity at 0.2C discharge is what most buyers go with for energy storage builds, but we've also done batches with a 5000mAh rating for applicaion where cycle life matters more than peak power, and that's a common swap we do without retooling.
It's basically an NCA chemistry cell, so you're getting higher energy density than LFP for the same weight, around 140g per unit, but the trade-off is thermal runaway risk above 60°C discharge — we don't recommend it for high-temp environments like engine bays or solar inverters without active cooling.
Minimum capacity is 5450mAh at 0.2C, and we test every batch with a 0.5C discharge to confirm it holds above 5300mAh — that's a spec we don't put on the datasheet but we track internally, and we'll share the raw data if you ask.
Anyway, teh 500-cycle life at 80% capacity is pretty standerd for this class, but if you're cycling at 1C or higher, expect that to drop to about 350 cycles or so — we usually have stock, but confirm lead time for custom BMS configurations.
Our standard MOQ for these cells is 10,000 units, but we can be flexible depending on your project. Reach out to our sales team for custom quantities.
Yes, we supply the CE, FCC, ROHS, UN38.3, and MSDS documents with every shipment. Just request them when you place your order.
For a standard bulk order, lead time is around 25-35 days. Custom packaging or labeling might add a few extra days.
We can adjust the capacity and slightly tweak dimensions for OEM/ODM orders, but the 32*70mm size is fixed for this model. Contact us with your specs.
For storage up to a year, keep them between -20°C and 25°C. For shorter periods, up to 45°C is fine. Avoid high humidity and direct sunlight.
