3.6V 4500mAh Molicel INR-21700-P45B

Molicel INR-21700-P45B

This is the newest cylindrical lithium battery which is launched by MOLICEL.  It comes with larger nominal capacity and higher energy density.  The NEW generation  consists of 45A  max discharging performance. And the fast charging capability has been hugely enhanced. The charging rate can up to 3C.

That is

It taks  less time to charge battery full. This newest generation-Molicel INR21700 P45B is a very good version.

In all, the launch of a new generation 21700 power cell, INR-21700-P45B, featuring 7% higher capacity however 22% lower DCR compared to P42A. Its consistent 45A discharging performance has now enhanced hugely with superior fast charge capability up to 3C charging rate.
