PRODUCT DETAILS
Complete product details — specifications, images, FAQ, and downloadable resources for this VoltCrave power solution

The D21 NMC polymer pouch cell provides a rated capacity of 50.5Ah, combining a flat cell structure with defined electrical performance for battery system integration.

With a nominal voltage of 3.65V and 185Wh energy, the cell provides a specified voltage range of 2.50V to 4.20V for battery pack engineering.
Standard charge and discharge currents are both specified at 17.3A (1/3C), providing consistent parameters for system design and cell integration.

The D21 cell is specified for 3000 cycles, supporting battery systems designed for repeated charge and discharge operation.
A specified AC impedance of ≤1.20mΩ provides a defined electrical resistance characteristic for pack design and cell performance evaluation.

The cell has a specified operating temperature range from -30°C to 55°C and a storage temperature range from 0°C to 60°C.
The supplied product uses a long, thin pouch construction with flat metallic terminal tabs at opposite ends, providing a distinctive form factor for battery module integration.
The cell is specified for applications including golf carts, electric bicycles/scooters, electric forklifts, electric vehicles and electric boats.
VoltCrave Power supports specification customization according to customer requirements, helping adapt battery solutions to different system and pack projects.
