Collomix XO 10 NC 18V Replacement Battery 3000mAh

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

This 18V Li-ion pack replaces the original battery on the Collomix Xo 10 NC cordless mixer and PRO HT Winkelschleifer. Capacity is 3000mAh (54Wh). Both tools share this battery platform, so one replacement covers either machine on-site.

• Xo 10 NC and PRO HT platform fit: Both tools run the same 18V rail and use an identical connector block and BMS handshake protocol. The pack registers correctly in either tool without modification.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on a load tester matched to the Xo 10 NC motor draw profile. The BMS held within spec at inrush and sustained load, and cell temperatures stayed within the protection window throughout.
• First-use mixer load cycling: On first use, run the Xo 10 NC at partial load — mixing lighter material or short stir cycles — for the first two uses before running full mortar or concrete batches. This lets the BMS record the motor's inrush current signature before locking overcurrent thresholds, reducing the chance of a nuisance trip on heavy mix.

BMS cutoff on the Xo 10 NC when mixing stiff mortar

The Xo 10 NC motor pulls a significant inrush spike the moment the paddle bites into stiff mortar or dry concrete mix. If the BMS has not yet mapped the motor's current profile, it can read that spike as an overcurrent fault and cut the pack. This happens most often on a new pack or one returning from storage. The fix is to give the BMS two or three light-load cycles first so it learns the motor's normal start current before it sees a full stiff-mix load.

Charger not recognising the pack after it has sat in storage

Li-ion cells self-discharge during storage. If the pack voltage drops below roughly 2.5V per cell, most chargers will not begin a charge cycle — the charger simply does nothing or flashes an error. A battery recovery charger with a wake or boost mode can apply a low-current trickle to bring cell voltage back above the acceptance threshold, typically around 3.0V per cell. Once the pack clears that threshold, a standard charger will recognise it and complete a normal charge cycle. If the pack does not respond to a recovery trickle after 30 minutes, the cells have degraded beyond recovery.
