King Kong ICR26650 4200mAh (Gold)
- Flat Top
- Volt: 3.7v
- Capacity: 4200mAh
- Charge current<=1A
- Weight 95 g
This battery is a unprotected 26650 battery, it does surpass the capacity specification.
The cells does not track perfectly, it looks like it is a resistance difference and not a capacity difference.
These cells does easly deliver 15A
The capacity has been increased compared to the 4000mA (As expected), but not with 200mAh (The 4000mAh did also have more capacity than rated).
The cell has a good performance, but they have a slightly different voltage when loaded.
I will rate this battery as acceptable.
