Molicel INR-21700-P50B 60A 5000mAh 3.6V cell
Molicel INR-21700-P50B 60A 5000mAh 3.6V cell
INR-21700-P50B sets a new standard with the most superior power-to-energy ratio ever achieved in a 21700 format. It features 5.0Ah for 100W discharge and 5C fast charge power. It delivers exceptional performance and, with its low impedance, ensures more efficient power delivery with minimal heat generation.
Compared to its predecessor, the P45B, the P50B offers significantly higher runtime, better retention, and a slower heating rate, effectively doubling the cycle life. This makes it ideal for high-demand applications where both power and endurance are essential.
