Description
The Crocks Pack 14.8V 14000mAh li-ion NMC Battery Pack INR 18650 Molicel 4S5P 13C Discharge
is a high‑energy, high‑current lithium-ion battery pack built for drones, UAVs, and high-performance RC systems. It uses sixteen Molicel INR 18650 P28A cells arranged in a 4-series by 4-parallel (4S4P) configuration, giving a nominal pack voltage of 14.8 V and a total capacity of 11.2 Ah. This provides a powerful mix of energy storage and discharge capability — ideal for long flight times plus strong motor bursts.
Each Molicel P28A cell is a high-drain 18650 cell, with a typical capacity of 2,800 mAh and a maximum continuous discharge current of 35 A, as per its datasheet. With 4 cells in parallel, the pack is designed to support a sustained discharge rate around 130 A (≈13C), giving you room for aggressive throttle, fast acceleration, or high-G maneuvers without overstressing the cells.
14.8v 14000mAh 4S5P cell has an internal resistance of about 20 mΩ (AC), which helps manage thermal loss and voltage drop under high current demand. Its voltage specifications are: nominal 3.6 V, full charge 4.2 V, and safe discharge cutoff around 2.5 V. With the 4S4P layout, the pack supports a balanced charging setup using a 4‑cell balance connector, ensuring safe and even charging across the series structure.
The pack is mechanically robust and designed to handle the vibration and stress typical of drone flight. With its high‑capacity and high-current rating, it is well suited for long-range quadcopters, heavy-lift UAVs, or utility drones that require both stamina and power.
