Description

The Overlander Molicel P50B 5000mAh 7.2V 2S1P Flat 21700 Li-Ion Battery - Deans (OL-3690) is a flat lithium-ion battery pack made from two Molicel P50B 21700 cells connected in series. It provides a 7.2V nominal output and 5000mAh capacity in a layout designed for applications where enclosure space is restricted. The fitted Deans connector provides the stated connection option for suggested compatibility with suitable RC models, robotics, portable electronics and custom projects.

The 2S1P configuration combines two cells in series without adding parallel cell groups, keeping the pack in a flat format. A JST-XH balance lead is included to support balanced charging of the cells. The pack is specified with a 260Wh/kg energy density and is intended to provide consistent energy delivery for applications requiring a slim battery arrangement.

This Li-Ion battery does not include built-in over-discharge protection. It should therefore only be used with equipment that provides appropriate voltage monitoring or a cutoff function. Charge it with a compatible Li-Ion charger using the correct voltage and current settings, and avoid overcharging, deep discharging and exposure to extreme temperatures. Monitor the battery while charging and using it, and store it in a cool, dry place away from flammable materials. Follow relevant local requirements when disposing of the used battery.
