The standard charging method is 0.2C constant-current charge to 3.65V followed by constant-voltage charge until current declines to 0.01C. The datasheet lists 1320mA as the standard charging and discharging current, 3300mA as the rapid charging current, and 3300mA as the maximum discharging current.
Cell and Pack Size Structure
The cell drawing and battery pack drawing define the long slim form factor used by this product. The pack drawing also identifies the connector as JST/PHR-2P with UL1007 24AWG red and black wires and blue PVC wrapping.
| Label | Description | Dimension |
|---|---|---|
| T | Battery pack thickness max. | 13.25 mm |
| W | Battery pack width max. | 28.15 mm |
| H | Battery pack height max. | 200.0 mm |

Operating Temperature and Retention
The specified operating temperature range is 10~45°C for charging and -20~60°C for discharging, with operating humidity ≤85%RH. The self-discharge test criterion states that discharge capacity is not less than 85% of initial capacity after the cell rests for 28 days at 20±5°C before 0.2C discharge to cut-off voltage.
Cycle Life and Safety Characteristics
The cycle life criterion is not less than 2000 cycles under the datasheet test method: 0.5C CC-CV charge to 3.65V, current decline to 0.02C, and 0.5C CC discharge to 2.3V until discharge capacity is reduced to 70% of rated capacity. Safety tests in the datasheet include overcharge, short-circuit, and thermal tests with criteria of no explosion and no fire under the stated test methods.
Protection Circuit
The PCB specification lists over-charge, over-discharge, over-current, and short-circuit protection functions. The PCBA parts list includes one protection IC, specified as S-8261ACEMD-G4ET2x or HY2112-CB, two DP8205 MOSFETs, resistors, a capacitor, and FR-4 PCB material.
Application Fit
The 3.2V 6600mAh capacity, LiFePO4 chemistry, protected 1S2P construction, and connectorized wire harness make this pack practical for moderate-current embedded devices such as smart meter modules, solar lighting controllers, IoT monitoring nodes, handheld instruments, security backup modules, and other custom electronics that can operate from a 3.2V LiFePO4 platform.
VTCBATT OEM/ODM Supply Notes
VTCBATT can support sample development, connector matching, wire length adjustment, labeling, protection circuit configuration, and battery wholesale for equipment manufacturers and distributors. Exact customization should be confirmed against the target device current profile, enclosure size, charge circuit, connector specification, and validation requirements.
