Ecovacs Deebot CR130 Compatible Battery 14.8V 2600mAh

Ecovacs Deebot CR130 / V780 — 14.8V Li-ion Replacement Battery (4ICR19/65)

This is a 14.8V 2600mAh Li-ion battery for the Ecovacs Deebot CR130 robotic vacuum and related models including the V780, KK8, and CR120. It replaces OEM part numbers 4ICR19/65 and INR18650-M26-4S1P. When the original cell loses capacity after repeated charge cycles, this is the direct swap that restores full motor and navigation power.

• CR130 / V780 / KK8 platform fit: These models share the same 4S1P 14.8V cell configuration, connector pinout, and BMS communication protocol — the reason one replacement battery covers all of them without wiring changes.
• Bench tested on actual hardware: We ran this cell through the CR130's BMS handshake sequence. The protection circuit recognised the pack correctly, cleared the charge lockout, and held voltage within the expected 16.8V fully charged ceiling.
• Dock charging on the CR130: Do not leave the Deebot sitting on its dock between cleans indefinitely. The CR130 dock does not cut trickle current reliably once the pack is full — continuous dock contact accelerates capacity fade. Charge to full, then remove from the dock until the next clean.

Suction dropping before the battery indicator reaches low on the CR130

The CR130's motor draws peak current when suction resistance increases — a partially blocked filter or brush roll causes the motor to pull harder than the BMS allows under sustained load. This triggers a voltage sag at the cell level before the state-of-charge indicator registers anything unusual. The indicator reads remaining charge, not instantaneous voltage under load. Clean the filter first; if the issue continues on a freshly cleaned filter, the original cell has degraded below the minimum voltage threshold the motor needs to maintain suction.

Motor cutting out mid-clean and recovering after a short pause

This is a BMS overcurrent trip, not a power failure. When the brush roll meets heavy carpet or a partial blockage, current draw spikes beyond what the protection circuit permits, and it shuts the pack down. The BMS resets after a short rest, which is why the robot recovers and resumes. Check the brush roll for hair wrap and the intake path for partial blockages before replacing the battery — a clear airway drops current draw back inside the BMS trip threshold.
