DUSLAN 11.1 V 2600 mAh lithium-ion battery pack

SKU CH-CXJ6-0MG9X

11.1 V lithium-ion pack with 2600 mAh capacity, built-in protection IC and 18650 cells

  • Battery TypeBattery Pack
  • 2600 mAh capacity powers devices longer between charges
  • 1 V nominal voltage matches equipment needing three-cell lithium-ion packs
  • Built-in 4 A protection PCB guards against over-charge, over-discharge and short circuits
  • 2 A polyswitch limits peak current and blocks reverse polarity
  • UN 38.3 passed for safe, regulation-compliant transport

Purpose & Audience

This 11.1 V lithium-ion pack delivers 2600 mAh and 28.08 Wh from three 18650 cells. It suits portable devices, custom power projects or backup units that require a compact 10.8–11.1 V source with integrated protection.

Voltage & Current Limits

The pack operates between 8.25 V cut-off and 12.6 V peak, with a nominal 10.8/11.1 V working range. An onboard 4 A PCB guards against over-charge, over-discharge, over-current and short circuits, while a 4.2 A polyswitch adds polarity and discharge limiting. Maximum charge current is 2.6 A and continuous discharge is capped at 4 A by the protection circuit.

Build & Connectivity

Cells are enclosed in PVC shrink wrap measuring 73 × 56 × 20 mm and weighing 150 g. Two 22 AWG leads, 6 inches long, exit the pack for direct soldering or connector attachment. The assembly has passed UN 38.3 testing for safe transport. No memory effect and a longer storage life than NiMH alternatives simplify long-term handling.

Questions about this item

Should I pick the 2600 mAh pack or a higher-capacity version?

This pack delivers 2600 mAh at 11.1 V nominal, giving 28.08 Wh; choose a larger pack only if your device needs more runtime than 28 Wh provides.

What does the 2600 mAh rating mean when the pack is inside my device?

At the 11.1 V working voltage the pack supplies roughly 28 Wh, so a 5 W load runs about five and a half hours before the 8.25 V cut-off triggers.

How does the built-in 4 A PCB protection limit real-world use?

The PCB caps continuous discharge at 4 A and peaks at 4.2 A via the polyswitch, so any load drawing more will be shut down to protect the cells.
