Maximum temperature raise at different discharge currents: 1A:+1,2°C, 2A:+3,4°C, 3A:+5,9°C, 5A:+11,1°C, 7A:+16,3°C, 10A:+23,0°C











Fairly standard NiMH discharge curves, the cell are not matches completely. They have a lot of capacity at low current draw and as usual the capacity goes down with load. At very high current (Above 5A) the cells need to be warm for best performance.















Conclusion

These batteries has good performance, especially at low current draw.
