VTC-LP105871 3.7V 5000mAh Li-ion Polymer Battery Pack Datasheet Overview
This article summarizes the VTC-LP105871 datasheet into buyer-ready product information for OEM device projects. The pack is a 3.7V 5000mAh rechargeable lithium polymer battery with protection circuitry, red/black wire leads, and a JST/PHR-2P connector.
Product Overview
The source specification describes the VTC-LP105871 as a Li-ion polymer rechargeable battery manufactured and supplied by VTC Power. The finished pack uses one LP105871 5000mAh cell with a PCB, two UL1007 22AWG wires, and one JST/PHR-2P connector. This format suits compact embedded equipment that needs rechargeable pack-level integration rather than a loose bare cell.

Pack Size and Mechanical Structure
The cell drawing lists a maximum initial cell thickness of 10.2mm, a maximum width of 58.0mm, and a maximum height of 71.0mm. The assembled pack drawing increases those limits to 10.4mm thickness, 58.5mm width, and 73.0mm height, with 100±5mm wires. These dimensions should be used for enclosure review and battery bay clearance.

Charging, Discharging, and Cycle Life
The datasheet specifies 4.2V as the limited charge voltage and 3.0V as the discharge cut-off voltage. Standard charge and discharge current are both 1000mA (0.2C), rapid charging and maximum discharging are both 2500mA (0.5C), and peak discharge is listed as 10000mA (2C) for less than one second. Cycle life is specified as not less than 600 cycles under the stated 0.2C charge/discharge test method until capacity reduces to 80% of rated capacity.
Protection Circuit
The battery pack includes a protection PCB. The parts list identifies an R5478N101CD protection IC and two DP8810 MOSFETs, while the PCB specification covers over-charge, over-discharge, over-current, and short-circuit protection behavior. The PCB material is described as RoHS-passing, but the datasheet does not state full-pack certification claims.
Application Fit
The 3.7V 5000mAh format is a strong fit for rechargeable portable devices, smart terminals, wireless modules, handheld data equipment, alarm panels, GPS trackers, and compact instruments where a thin pouch pack with a 2-pin connector is preferred. Device designers should still validate current demand, enclosure clearance, thermal behavior, and charge-system compatibility during sample testing.
VTCBATT OEM/ODM Supply Notes
VTCBATT can support lithium polymer battery pack projects with connector selection, wire length adjustment, pack labeling, protection circuit matching, sample development, and factory-direct wholesale batch supply. For new projects, share the target device current profile, available battery bay dimensions, connector drawing, and charging method so the pack can be reviewed against the datasheet limits.
