Review conclusion	With reservations	Recommended

Only in one review: Voltage 3.7 V (LiitoKala 26650-55A); Current 70 A (Reliance INR21700-RS50); Capacity 5200 mAh (Reliance INR21700-RS50); Test current 40 A (Reliance INR21700-RS50); Resistance 3 mΩ (Reliance INR21700-RS50).

Reliance INR21700-RS50: High capacity and strong results, but they heat up and sag under heavy load; the author preferred EVE for high loads.

LiitoKala 26650-55A: The cell delivered good current and its stated capacity, but the author would prefer the Lii-51S.
