Outstanding For Maximum Balanced Cell !! May 25, 2019
Reviewer: Daniel C. from Knoxville, TN United States  
The best 21700 size cell for maximum balance of High Drain & Upper Middle Level Capacity.   Very Nice Balance for those that DO NOT want to compromise between capacity and high drain capability.   It's a true Goldilocks type cell.  Excellent runtimes while under high drain as well, it really maintains its voltage better than any other cell in the 21700 form factor.  I highly recommend these cell to anyone who compromise capacity for high drain capability or vice versa.   These also are legitimate and genuine cells that come direct from Molicel via their distribution NPE.  No shenanigans nor any other proxies involved through the process chain.   They are fresh date codes and authentic.

WOW just WOW May 16, 2019
Reviewer: Amberly Campbell from Portland Oregon  
the molicel p42a 21700 batteries are definitely NEXT level batteries.. these easily last longer than my Samsung 40t batteries while at the same time hitting just as hard as my 30t batteries!! I've tested these p42q batteries back to back with 30t in my mechs and the 30t drops off at around 3.7v while the p42a not ONLY hits as HARD as the 30t imo it holds it's voltage much BETTER..it continues to hit HARD all the way down to 3.3v!! These are the overall BEST 21700 batteries I've ever owned! Highly recommend them!
