This is protected 18650 batteries with fairly low capacity.

The two batteries are well matches and can easily handle the 5A load, but the capacity is even lower than rated.

Conclusion
These protected battery works well and the protection trips early enough to protect them from getting to hot, but the capacity is rather low and significantly below the rated capacity.
Even though the tested batteries looks fine, I would not trust this brand, due to the large discrepancy between rated and actual capacity. It might be the cheapest available battery that is stuck in the wrapping!
