Sony US18650VC7 3400mAh (Green)



Official specifications:

• Nominal capacity: 3500mAh (2V cut-off)
• Rated capacity: 3400mAh (2V cut-off)
• Capacity at 5A: 2720mAh (2.5V cut-off)
• Nominal voltage: 3.6V
• Charge voltage: 4.2V +/- 0.05V
• Charge current: 1.0A.
• Discharge current: up to 8A.
• Cycle life: 300 cycles to 70% at 1A charge and 5A discharge, 2.5V cut-off.

This is high capacity cells that can deliver a decent amount of current, but are not high current cells.











The discharge curves tracks nicely, capacity may look at bit low, but that may be because I do not discharge to 2V. They easily matches the 5A rated capacity.



















Conclusion

Very good high capacity batteries from a big brand.

Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.
