King Kong ICR26650 4000mAh (Gold)
- Capacity: 4000mAh
- Size: 26mmx66mm.
- Charge current: <=1a?
- Weight: 95 g
The capacity is well above the marked value.
The two cells has the same capacity, but the voltage is not the same at higher loads.
The cells has a good performance, but they has a slightly different voltage when loaded.
I will rate this battery as acceptable.
