Edding Portable 12 18V Replacement Battery 6000mAh Li-ion

Edding Portable 12 / LO-G-PO-12 — 18V Li-ion Replacement Battery

This is an 18V Li-ion replacement battery rated at 6000mAh (108Wh) for the Edding Portable 12 and LO-G-PO-12 cordless tools. It fits drilling, fastening, and cutting applications in the Portable 12 platform. Voltage and cell chemistry match the original pack specification.

• Portable 12 and LO-G-PO-12 platform fit: Both models share the same 18V battery rail, connector footprint, and BMS communication protocol — one pack works across either tool without modification.
• Bench tested on actual hardware: We cycled this pack through full charge and discharge sequences, monitoring BMS behaviour under simulated motor-start inrush spikes. The overcurrent protection reset correctly after each trigger-pull event without latching fault.
• Motor break-in on first use: Run the tool at half load for the first two cycles before full-torque applications. This allows the BMS to profile the motor's inrush current draw and calibrate overcurrent thresholds before you hit peak demand.

BMS cutoff on motor-start inrush surge

When you pull the trigger hard on a drill or saw, current demand spikes sharply in the first milliseconds before the motor reaches operating speed. If the BMS overcurrent threshold is set conservatively — common on fresh packs — that spike can trip a protective cutoff. The tool goes dead on the pull, even with a fully charged battery. Short, light trigger-pulls for the first two cycles trains the BMS threshold to the actual motor profile and prevents nuisance trips.

Tool bogs under load despite showing full charge

This is voltage sag — under heavy draw, the pack rail voltage drops enough that the tool loses torque even though resting voltage reads 18V. The most common cause is high contact resistance at the battery terminal, not cell degradation. Clean the battery contacts and tool bay with isopropyl alcohol, reseat the pack firmly, and retest under load. If sag persists, check resting voltage with a multimeter — a healthy fully charged 18V Li-ion pack should read approximately 20.5–21V at rest.
