Yeedi K600 Robotic Vacuum Compatible Battery 14.4V 2600mAh

Yeedi K600 / K650 / K680 / K700 — 14.4V Li-ion Replacement Battery

This is a 14.4V, 2600mAh (37.44Wh) lithium-ion battery for the Yeedi K600, K650, K680, and K700 robotic vacuum cleaners. It replaces the original pack when capacity has dropped and the unit can no longer complete a full cleaning cycle. The cell format and connector match the stock battery compartment on all four models.

• K600 / K650 / K680 / K700 platform fit: All four models share the same 14.4V battery bay, connector pinout, and BMS handshake protocol. A single cell revision covers the entire lineup without modification.
• Bench tested on actual hardware: We cycled this pack on the K600 motor platform. The BMS held charge correctly across full discharge and re-charge cycles, and the protection circuit tripped as expected under overcurrent conditions before recovering cleanly.
• Dock charging habit on robotic vacuums: Do not leave the K600 sitting on the charging dock indefinitely between uses. Continuous trickle charge accelerates cell degradation faster than any other single factor on this platform. Charge to full, then remove the unit from the dock until the next session.

Suction dropping before the battery indicator reaches low on the K600

This happens when the motor draws sustained high current — typically caused by a partially blocked filter or brush roll restriction. The battery voltage sags under load even though the cell still holds charge, causing the motor controller to reduce power before the indicator triggers. The BMS reads pack voltage, not motor load, so the indicator lags behind what the motor is actually experiencing. Clear the filter and brush roll first, then recheck suction at full charge — if it holds, the battery was compensating for a restriction, not failing.

Motor cuts out mid-run and then recovers after a short pause

This is a BMS overcurrent trip, not a loose connection. When the brush roll hits heavy carpet or a debris buildup, the motor draws a spike of current that crosses the BMS protection threshold. The pack disconnects momentarily, then reconnects once the overcurrent condition clears — which is why the robot resumes after a few seconds. Check the brush roll for tangled hair or debris causing sustained drag. If the cutout repeats on clear flooring, the original pack's cells have degraded enough that even normal motor draw is crossing the trip point — that is when replacement is warranted.
