Collomix 18V Li-ion Replacement Battery XO 10 NC 2000mAh

Collomix Xo 10 NC — 18V Li-ion Replacement Battery

This is an 18V Li-ion battery rated at 2000mAh (36Wh), built to replace the original pack in the Collomix Xo 10 NC cordless mixer and PRO HT Winkelschleifer. The Xo 10 NC is a construction-grade mortar and material mixer used for blending concrete, plaster, tile adhesive, and similar compounds. Voltage and cell count match the original pack exactly.

• Xo 10 NC and PRO HT Winkelschleifer compatibility: Both tools run on the same 18V rail and share the same connector format and BMS handshake protocol. Swapping batteries between these two tools is standard practice on Collomix platforms — this pack supports both without modification.
• Bench tested on actual hardware: We cycled this pack through full charge and discharge sequences, monitoring BMS response during motor-start inrush events. The overcurrent protection triggered correctly at high-draw spikes and reset without manual intervention after load was removed.
• First-use load conditioning on a mixer: On first use, run the mixer at half load for two cycles before tackling full-batch concrete or tile adhesive. This lets the BMS profile the motor's inrush current draw and calibrate its overcurrent thresholds before sustained heavy mixing sessions.

BMS cutoff on motor-start inrush during thick-batch mixing

When the Xo 10 NC starts under a heavy load — dense mortar, thick adhesive, or a partially set batch — the motor draws a large inrush current spike in the first fraction of a second. If the BMS reads that spike above its overcurrent threshold, it trips and cuts power immediately. This is not a battery fault; it is the protection circuit doing its job. Remove the paddle, clear the batch resistance, then restart the mixer unloaded before re-engaging the material.

Charger not recognising this pack after storage

Li-ion packs that have sat unused for several months can drop below the charger's acceptance voltage — typically under 2.5V per cell. When this happens, the charger blinks an error or does nothing at all. Most Collomix-compatible chargers have a recovery or trickle mode; consult the charger manual and activate it if available. If no recovery mode exists, a compatible charger with a manual boost function can bring the pack back up to 3.0V per cell, at which point normal charging resumes.
