DUSLAN 3.2V 800mAh 18500 LiFePO4 battery pack GS-139

SKU CH-V9F4-7KWVA

3.2 V 800 mAh LiFePO4 18500 pack with built-in protection IC and clip connector for GS-139 solar lights

  • 2 V nominal voltage powers GS-139 solar lights reliably
  • 800 mAh capacity delivers 9.6 Wh energy for extended runtime
  • LiFePO4 chemistry provides over 1000 charge cycles for multi-year use
  • Built-in IC chip prevents over-charge and over-discharge to protect cells
  • 18500 form factor with clip connector enables quick drop-in replacement

Purpose & Fit

This 3.2 Volt 800 mAh LiFePO4 pack replaces the original cell in Gama Sonic GS-139 solar lights. The 18500 form factor and included male adapter clip let owners restore runtime without soldering or special tools.

Build & Daily Use

Lithium phosphate chemistry delivers over one thousand charge cycles and stable output up to a 7 Amp discharge limit. An onboard IC guards against over-charge and over-discharge, while the chemistry tolerates high ambient temperatures better than standard lithium-ion cells.

Upgrade Context

The pack suits fixtures that shipped with a single 18500 LiFePO4 cell and a compatible clip connector. It will not fit lights that use a different voltage, a larger cylindrical size, or a proprietary multi-cell housing.

Questions about this item

What does the 3.2 V LiFePO4 chemistry mean for the maximum charge and discharge currents on this GS-139 pack?

The integrated IC limits charging to 1.5 A and discharging to 7 A, protecting the 800 mAh cell from over-charge and over-discharge.

Will the 18500 cell with its 18 mm diameter and 65 mm length fit the GS-139 lamp housing?

Yes, the pack measures 18 mm diameter by 65 mm long and includes a plug-in clip designed for direct replacement in GS-139 series fixtures.

How do you install the pack and what is the step users often miss?

Open the battery compartment, unclip the old pack, connect the supplied male adapter to the new pack, then clip it in — forgetting the adapter leaves the pack unpowered.
