Product Details
The GEB 14.8V 2700mAh 4S1P Cylindrical Li-ion Battery Pack with Integrated BMS is a commercial-grade pre-configured lithium-ion battery pack engineered for portable medical instruments, mobile robotics, and industrial instrumentation. Formed with 4 series-connected Grade-A 18650 cylindrical cells delivering a verified 14.8V nominal voltage (16.8V peak charging cutoff) and 2,700mAh rated capacity (39.96Wh total energy), this pack features an integrated Battery Management System (BMS) with hardware protection against over-voltage (OVP), under-voltage (UVP), over-current (OCP), and short circuits. Encapsulated in flame-retardant blue PVC shrink wrap with pure nickel busbars and dedicated cell spacing brackets, it provides continuous 1.0C–2.0C discharge (2.7A–5.4A) with stable thermal dissipation.
Product Overview
The GEB 14.8V 2700mAh 4S1P Cylindrical Li-ion Battery Pack with Integrated BMS is an engineered modular power assembly built with four premium Grade-A 18650 cells in a 4S1P series configuration. Featuring a 14.8V nominal operating voltage (with 16.8V full-charge regulation) and 2700mAh rated capacity (39.96Wh), this pack incorporates an integrated PCM/BMS protection board that actively safeguards against overcharge, overdischarge, overcurrent, and thermal anomalies. With physical dimensions of Approx. 72.0 × 66.0 × 19.0 mm (inline 4S) and calibrated net weight of Approx. 210g ± 10g, it is encased in high-grade insulated PVC heat shrink tubing with high-flexibility 20AWG silicone leads. Optimized for portable medical diagnostic monitors, survey devices, telecom test sets, security inspection cameras, and robotic drive units.

Equipment Compatibility & Engineering Fit Check
Before deploying GEB 14.8V 2700mAh 4S1P Cylindrical Li-ion Battery Pack with Integrated BMS, verify these verified electrical and mechanical boundary requirements:
Operational Boundary Conditions
✔ Recommended Fit & Use Cases:
- Electronic devices and OEM packs matched with 14.8V / 2.7Ah power curves.
- Commercial designs requiring high volumetric energy density and predictable discharge curves.
- Projects requiring batch consistency with automated barcode impedance sorting.
⚠ Operational Constraints & Limits:
- Do not discharge below minimum cutoff voltage or charge beyond 16.8V.
- Maintain operational surface temperature within -20°C to +60°C discharge (0°C to +45°C charge).
- Ensure connector polarity and pin assignment match system schematics prior to initial power-up.
