Samsung INR18650-15Q 3.33C (5A) Test

At 3.33C (5A) loads

At 1C (1500mA) loads

Samsung has this model which has a 18A discharge rate, At 3.33C (5Amps) it performs similar to the panasonic CGR18650CH but only for 17 minutes. It performs with around 96-93% capacity and the temperature is quite low (mostly because of the high discharge rate it didn't bother much). Here is some data at 5A loads

Pass!    Capacity=1,398 Ah (93,2% rated); Energy=4,663 Wh

Summary:
1. One Hour Discharge: Pass; Capacity=1,440 Ah (96,0% rated); Energy=4,805 Wh; IPV=3,787V; MPV=3,377V; EPV=2,756V; MPI=5,003 A.
2. Lithium-ion Charge: Capacity=1,416 Ah (94,4% rated); Energy=5,552 Wh.
3. One Hour Discharge: Pass; Capacity=1,398 Ah (93,2% rated); Energy=4,663 Wh; IPV=3,775V; MPV=3,377V; EPV=2,751V; MPI=5,003 A.
4. Li-ion 30% Charge: Capacity=450,2 mAh (30,0% rated); Energy=1,637 Wh.
