[size=+3]LiitoKala 26700 4000mAh Lii-40E (Orange)[/size]
Official specifications:
A LiFePO4 in 26650 size with fairly good capacity.
The two cells matches very nicely and can deliver the rated 3C or 12A.
[size=+3]Conclusion[/size]
This is a good LiFePO4 battery and as usual for this type it has very stable output voltage and less energy contents than the more common LiIon types, but longer life.
