Description
The Crocks Pack Moli INR 18650 P28A 14.8V 2800mAh 4S1P 30A/35A Discharge Li-ion Drone Battery Pack
is a compact, high-quality Li-ion battery pack tailored for drones and RC setups that require a balance of voltage, energy, and continuous power. Built from four genuine Molicel INR 18650 P28A cells wired in series (4S), this pack delivers a nominal voltage of 14.8 V and a total capacity of 2800 mAh, making it ideal for smaller quadcopters, fixed-wing aircraft, or any setup where high energy density and moderate current output are necessary.
Thanks to the P28A cell’s reliable power characteristics, the pack supports a continuous discharge current of 30 A, with the capability to handle peak bursts up to 35 A. This ensures smooth throttle response and reliable performance, without pushing the cells to extreme thermal stress.
The Molicel P28A cell is known for its low internal resistance (20 mΩ AC) and very good cycle stability. The cell has a nominal voltage of 3.6 V, a typical capacity of 2800 mAh, and can be safely charged to 4.2 V, with a recommended cut-off discharge voltage of 2.5 V for longevity. Each cell measures 18.6 mm in diameter by 65.2 mm in height and weighs approximately 46 g.
For charging, the pack includes a 4-cell balance connector, helping to maintain voltage balance across all series cells. The discharge lead is designed to reliably carry the specified current, and the robust construction ensures the pack handles vibration and handling typical of RC aircraft.
