  • 4 V output powers compatible devices reliably
  • 800 mAh capacity supports extended run time between charges
  • Built-in protection IC guards against over-charge, over-discharge and short circuits
  • 2 A polyswitch limits peak discharge and blocks reverse polarity

7.4 V 800 mAh 14500 pack

This DUSLAN battery pack combines two 14500 lithium-ion cells in a shrink-wrapped module measuring 2" x 1.1" x .55" and weighing 1.6 Oz. It delivers a working voltage of 7.4 V with a peak of 8.4 V and a cut-off of 4.8 V. An on-board 3.0 A protection IC guards against over-charge, over-discharge and short circuits. A 1.2 A polyswitch adds polarity and current limiting.

Suits portable 7.4 V devices

The pack fits equipment designed for a 7.4 V nominal supply drawing up to 800 mA continuous or 1.2 A peak, such as compact instruments, hobby electronics or custom LED projects. It is not for devices needing a higher capacity than 800 mAh, a voltage other than 7.4 V, or a form factor larger than the 14500 cylindrical size. Applications requiring user-replaceable single cells should look elsewhere.

800 mAh capacity at 7.4 V

The single specification that decides fit is the 800 mAh capacity at 7.4 V, which fixes both run-time and maximum continuous current at 800 mA. Verify the target device's current draw and voltage window against the 4.8 V cut-off and 8.4 V peak before purchasing.

Questions about this item

Will the 7.4 V 800 mAh pack replace the two 14500 cells in my older device without wiring changes?

The pack uses two 14500 cells in series with 12 G wire leads, so it fits the same space as two loose AA-sized cells and connects directly to existing leads.

How can I verify the protection IC is active after the first charge?

Measure the pack voltage; it should read near 8.4 V at full charge and the PCB will cut output if voltage drops to 4.8 V or current exceeds 3.0 A.

Does the shrink-wrapped module include a charger or only the battery with leads?

Only the PVC-wrapped 7.4 V pack with 12 G wire leads is supplied; a compatible Li-ion charger must be purchased separately.
