Battery Sony Murata US21700VTC6A 4100mAh - 40A
Introducing a cylindrical 21700 form factor battery, listed in the product card as a Sony brand product (model Sony Murata US21700VTC6A 4100mAh - 40A). However, the technical specifications provided below correspond to the Samsung INR21700-50S model — the description compiles all available parameters and operational requirements so you can assess the compatibility and capabilities of the cell.
The battery is designed in a 21700 form factor with a hard cylindrical casing, 1S1P configuration. The hard construction provides enhanced mechanical strength and ease of integration into various devices and DIY battery packs. The cell has a low self-discharge rate and exhibits no memory effect, which is important for long-term use.
Electrical parameters and operational characteristics: nominal voltage 3.6 V; in standard continuous mode, current output is 9.8 A (2C), pulse current output up to 14.7 A. Recommended charging mode 0.33C (1.25 A) for a standard cycle with fast charging capability up to 4 A. Please note the discrepancies in sources: the product title indicates 4100 mAh and 40A, while the specification table lists a capacity of 4850 mAh — when selecting a cell, always check compatibility with your device and the actual markings on the cell.
The battery has high cyclability: it retains more than 80% of its initial capacity after 500 cycles, making it cost-effective for long-term use. The cell is supplied without built-in connectors and without balancing connectors; connection is intended by welding (Flat top).
