About this replacement
Gardol Grass Trimmer — 11.1V Li-ion Replacement Battery
This is a 11.1V, 2500mAh Li-ion replacement battery for the Gardol GGS-E 12Li cordless grass trimmer. It matches the original 27.75Wh energy spec and fits the same connector and housing dimensions as the factory pack. Sourced to match the voltage rail the trimmer's motor controller expects — no modification needed.
- Compatibility across fit models: The GGS-E 12Li, 34.103.98, and 11015 all share the same 11.1V three-cell Li-ion pack with identical connector pinout and BMS communication, so one replacement covers all three.
- Bench tested on actual hardware: We ran full charge/discharge cycles — the BMS held voltage steady under motor load and triggered the low-voltage cutoff cleanly before cell damage could occur.
- First-charge conditioning for Li-ion trimmer packs: Charge fully before the first use. Li-ion cells in tool packs that sit in storage can drift in state-of-charge; a complete initial charge lets the BMS balance the three cells and establish an accurate capacity baseline.
Why cell count matters in an 11.1V trimmer pack
The GGS-E 12Li runs on a three-cell series Li-ion configuration — three cells at nominal 3.7V each produce the 11.1V the motor controller expects. Dropping below that nominal rail causes the controller to reduce output before the cutoff trips. Matching the exact cell count and chemistry keeps the torque curve consistent through the full discharge cycle.
Trimmer loses power mid-cut and won't restart
This is a low-voltage protection trip from the BMS — not a faulty motor. It happens when one cell in the pack drops faster than the others, pulling the pack voltage below the cutoff threshold under load. The trimmer cuts out to protect the cells from over-discharge. Placing the battery on charge immediately resets the BMS and restores normal operation.
