About this replacement
Metabo BS 14.4 LTX Impuls — 14.4V Li-ion Replacement Battery (6.25467)
This 14.4V 3000mAh Li-ion battery replaces the original pack on the Metabo BS 14.4 LTX Impuls cordless drill-driver and fits additional 14.4V Metabo platforms including the ULA 14.4-18 and BS 14.4 6.02105.50/51 variants. It matches OEM part numbers 6.25467, 625498000, 625526000, C98116, and 6.25454. Capacity is 3000mAh at 14.4V nominal, 43.2Wh total.
- Cross-model 14.4V platform fit: The BS 14.4 LTX Impuls, ULA 14.4-18, and related BS 14.4 variants share the same 14.4V rail voltage, slide-in connector geometry, and BMS communication protocol — which is why a single pack covers the range without modification.
- Bench tested on actual hardware: We cycled this pack through repeated load pulls on a BS 14.4 LTX Impuls body. The BMS held stable through trigger-pull inrush spikes and did not trip overcurrent protection under normal fastening cycles. Cell voltage balance across the pack stayed within 30mV at full discharge.
- Break-in procedure for LTX drill packs: On first use, run the drill at half load for two full cycles before maximum torque applications. This lets the BMS log real inrush current from the LTX motor and set accurate overcurrent thresholds — skipping this can cause nuisance BMS trips on hard fastening tasks.
BMS cutoff on trigger-pull inrush with the BS 14.4 LTX motor
The LTX Impuls motor draws a short inrush spike the instant the trigger is pulled — often 3–5x the steady running current. A new pack with a freshly reset BMS has no inrush history logged, so the overcurrent threshold may sit lower than the actual spike requires. This causes the pack to cut out immediately on trigger pull even though nothing is mechanically wrong. Running two break-in cycles at reduced load gives the BMS enough data to raise the trip threshold to match the motor's actual start current. After break-in, full-torque trigger pulls should hold without cutoff.
Charger not recognising the pack after storage
Li-ion cells left in storage for several months can drop below the charger's acceptance threshold — typically around 2.5V per cell. The Metabo charger sees a voltage below its wake-up window and refuses to begin a charge cycle, often showing a fault blink. The fix is a trickle or recovery charge: if your charger has a recovery mode, activate it; if not, a compatible Li-ion recovery charger can bring cell voltage back above 2.8V per cell. Once individual cells read above 2.8V, a standard charger will recognise the pack and resume normal charging.
