Kealive I6 Robot Vacuum Replacement Battery 14.8V 2600mAh

Kealive I6 Robot Vacuum Cleaner — 14.8V Li-ion Replacement Battery

This is a 14.8V 2600mAh (38.48Wh) lithium-ion battery for the Kealive I6 Robot Vacuum Cleaner. It replaces the original cell pack that powers the drive motors, brush roll, and onboard navigation electronics. Fit the replacement when the original battery no longer holds charge or causes the unit to stop mid-cycle.

• Kealive I6 fitment: The I6 uses a 14.8V four-cell Li-ion pack with a specific connector and BMS communication line. This battery matches that voltage rail and connector format, so the vacuum's charge management and low-battery shutoff logic operate as expected.
• Bench tested on actual hardware: We cycled this pack through charge and discharge under motor load. The BMS held cutoff correctly at low voltage and accepted a full charge without triggering an error state on the dock.
• Dock charging habit on the I6: Do not leave the I6 sitting on the charging dock permanently. Continuous dock contact applies a trickle charge that degrades cell capacity faster than normal cycling. Charge the battery to full, then remove the unit from the dock until the next clean.

Suction dropping before the battery indicator reaches low

On the I6, the brush roll motor is the biggest current draw in the system. When the filter is partially blocked or the brushes are tangled, that draw spikes. The battery's BMS responds by throttling output to protect the cells, which the vacuum registers as reduced suction — not low battery. Clean the filter and check the brush roll before assuming the battery is at fault. If suction recovers after a filter clean, the pack is not the cause.

Motor cuts out mid-clean then restarts on its own

This is an overcurrent trip, not a battery failure. When the I6 hits a sustained restriction — a dense rug, jammed brush, or clogged suction path — current draw exceeds the BMS threshold and the pack shuts output momentarily to protect itself. The BMS resets after a few seconds, which is why the motor restarts. Clear the blockage and check that the filter is clean. If the cutout continues on an unobstructed hard floor, check that the replacement pack's BMS handshake is accepted by cycling power fully off, then back on.
