Description
The Overlander 5000mAh 7.2V 2S Config 2 21700 Li-Ion Battery - Deans (OL-3741) is a flat lithium-ion battery pack for RC models, robotics, portable electronics and custom projects. It uses two 21700 cells connected in series to provide a 7.2V nominal output and 5000mAh capacity. The flat 2S1P arrangement is suited to installations where a slim battery profile is useful, while the Deans connector provides the pack's main power connection.
This battery is designed to provide consistent output and high discharge capability under load. Its cell construction supports cycle life and thermal stability during use, and the flat layout can be integrated into tight enclosures or positioned alongside other components. A JST-XH balance lead is included to allow the individual cells to be balanced during charging.
Features
The pack is intended for users who need a 2S lithium-ion power source for RC electronics, robotics or other custom equipment. It does not include built-in over-discharge protection, so the equipment being powered must provide suitable voltage monitoring or a cutoff function. Use a compatible Li-Ion charger with the correct voltage and current settings.
Safety and Use
Follow the charger and battery manufacturer's instructions when charging, using or storing this pack. Do not overcharge or deeply discharge the battery, and monitor it during use and charging to help prevent overheating. Never leave it unattended while charging. Store it in a cool, dry location away from flammable materials, and dispose of the battery in line with local regulations.
