SUZUKA KAKA P2 Cordless Vacuum Replacement Battery 14.8V 3400mAh

SUZUKA KAKA P2 — 14.8V Li-ion Replacement Battery

This is a 14.8V, 3400mAh (50.32Wh) lithium-ion battery pack for the SUZUKA KAKA P2 cordless stick vacuum. It replaces the original cell when capacity has dropped or the pack no longer holds a charge. Swap it in to restore full power to the motor and suction head.

• KAKA P2 motor voltage rail: The KAKA P2 runs a brushless motor on a 14.8V nominal rail. Dropping below that threshold — even briefly — causes the motor controller to reduce speed before the battery indicator shows low. This cell maintains the correct voltage window to keep the motor at rated speed through the full discharge cycle.
• Bench tested on actual hardware: We ran this pack on a KAKA P2 unit under both hard-floor and carpet load. The BMS held stable across sustained high-draw passes and tripped cleanly on a blocked-filter condition, cutting power before the motor overheated.
• Dock charging discipline on the KAKA P2: The KAKA P2 charging dock supplies a trickle current when the pack is full. Leaving the vacuum docked permanently stresses the cells and accelerates capacity fade. Charge only when depleted, then remove the vacuum from the dock once the indicator shows full.

Cordless vacuum losing suction before the battery indicator reaches low

This happens when a partially blocked filter forces the motor to draw more current than rated. Increased current draw causes the cell voltage to sag under load, and the motor controller interprets that voltage drop as low battery before the pack is actually depleted. The indicator reads mid-charge because it is measuring resting voltage, not load voltage. Clear the filter first — if suction restores, the battery is not the cause. If the filter is clean and the sag persists, the pack has lost enough capacity that load voltage drops below 13.0V during normal operation.

Motor cuts out mid-clean then recovers after a few seconds

This is a BMS overcurrent trip, not a dead battery. It happens when sustained restricted airflow forces the motor into a high-draw stall condition — the BMS cuts power to protect the cells, then resets after a short timeout. Check the filter and all airway channels for partial blockage before replacing the battery. If the motor still trips on a clear airway, confirm the pack is fully charged to 16.8V before running a second test — a low-state pack trips overcurrent protection at a lower threshold than a full one.
