DUSLAN 11.1V 5200 mAh Li-ion battery pack 6x18650

SKU CH-YB50-FKSEK

11.1 V lithium-ion pack built from six 18650 cells delivers 5200 mAh with a 7 A protection board and 56 Wh capacity

  • Battery typeBattery Pack
  • 1 V nominal voltage powers 12 V devices reliably
  • 5200 mAh capacity extends runtime for portable projects
  • Built-in 7 A protection PCB guards against over-charge and short circuits
  • Compact 76 × 64 × 38 mm size fits tight enclosures

Portable 11.1 V power pack for custom projects

This DUSLAN lithium-ion battery pack delivers 5200 mAh at a nominal 11.1 V from six 18650 cells. It is aimed at makers, robotics hobbyists and engineers who need a compact, high-energy-density source for portable electronics or backup systems.

Built-in protection limits current and voltage

A 7 A PCB guards against over-charge above 12.6 V, over-discharge below 8.25 V, over-current and short circuits. A 7 A polyswitch adds reverse-polarity protection and caps discharge at 7 A. The pack accepts up to 5.2 A charge current and stores 56 Wh with no memory effect.

Replaces loose cells or NiMH packs in tight spaces

The 76 × 64 × 38 mm PVC-wrapped module fits where individual 18650 cells or bulkier nickel-metal-hydride packs cannot. Pre-fitted 16 AWG leads simplify wiring for drones, RC vehicles or test-bench supplies. It is not suited for applications needing higher voltage, greater capacity or user-swappable cells.

Questions about this item

How do I connect the 6-inch 16 AWG leads, and what polarity mistake do installers make?

Solder or crimp the red lead to positive and the black lead to negative on your device; the built-in polyswitch blocks current if you reverse them, so verify polarity before sealing the enclosure.

What part of the 11.1 V pack wears out first and when should I plan a replacement?

The six 2600 mAh 18650 cells degrade with each charge cycle; replace the pack when run-time falls far short of the rated 5200 mAh or the voltage sags under load.

Which protection limit triggers first during a long high-current draw?

The 7 A PCB and polyswitch both cap continuous discharge at 7 A; sustained loads near that level will hit the current limit before the 8.25 V cut-off voltage is reached.
