Collomix XO 10 NC 18V Replacement Battery 6000mAh

Collomix Xo 10 NC / PRO HT Winkelschleifer — 18V Li-ion 6.0Ah Replacement Battery

This is an 18V, 6000mAh Li-ion replacement battery for the Collomix Xo 10 NC cordless mortar mixer and the PRO HT Winkelschleifer. Both tools run on the same 18V rail and share the same battery footprint and connector. Capacity is sourced from product data at 6000mAh (108Wh).

• Xo 10 NC and PRO HT compatibility: Both tools share the same 18V battery platform, connector pin layout, and BMS handshake protocol. Swapping packs between them requires no adapters — the communication line reads the same cell data on both platforms.
• Bench tested on actual hardware: We ran this pack through repeated high-torque mixing cycles on the Xo 10 NC. The BMS handled motor-start inrush current without tripping, and cell temperatures stayed within safe limits across sustained load cycles.
• Motor inrush break-in on first use: On first use, run the Xo 10 NC at half-load mixing for two cycles before full-torque applications. This allows the BMS to profile the motor's inrush current draw and calibrate overcurrent protection thresholds before you hit dense mortar or adhesive compounds.

BMS overcurrent trip on motor-start inrush during mixing

The Xo 10 NC draws a significant current spike the moment the motor starts under load — especially in thick tile adhesive or concrete grout. If the BMS has not yet profiled that inrush pattern, it can trip the overcurrent threshold and cut power instantly. This looks like the mixer dying on trigger pull rather than running weak. Starting each session with a half-load first mix gives the BMS a reference reading before the pack sees full motor demand.

Pack voltage too low for charger acceptance after storage

Li-ion cells self-discharge during storage. If a pack sits unused long enough, cell voltage drops below the threshold the charger checks before it starts a charge cycle — typically around 2.5V per cell. The charger sees voltage below its acceptance floor and refuses to begin, often blinking red or showing no charge activity at all. To recover the pack, check cell voltage with a multimeter; if individual cells read above 2.0V, a compatible charger with a recovery or wake-up mode can bring them back to the 2.5V floor before normal charging begins.
