Eufy RoboVac LR30 Hybrid 14.4V Compatible Battery T2996011

Eufy RoboVac LR30 Hybrid Series — 14.4V Li-ion Replacement Battery (T2996011)

This is a 14.4V, 2600mAh (37.44Wh) Li-ion replacement battery for the Eufy RoboVac LR30 Hybrid and RoboVac LR30 Hybrid+. It slots into the battery compartment in the robot's underside and powers the drive motors, suction fan, and navigation sensors. OEM part number T2996011 confirms the fit across both LR30 Hybrid variants.

• LR30 Hybrid and LR30 Hybrid+ compatibility: Both models run the same 14.4V power rail and use an identical battery bay connector with matching BMS handshake requirements. The cell configuration — four 18650 cells in series (4S1P) — matches the original pack's voltage profile so the robot's charge controller recognises the battery correctly.
• Bench tested on actual hardware: We ran the battery through charge and discharge cycles on the LR30 platform. The BMS held the discharge cutoff at the correct low-voltage threshold and passed the charger handshake without triggering a fault state on the dock.
• Dock charging habit for the LR30: Do not leave the LR30 sitting on its dock continuously between uses. The LR30 dock trickle-charges the pack even when full, and sustained trickle current accelerates capacity fade in Li-ion 4S packs. Charge to full, then remove the robot from the dock until the next clean.

Suction dropping before the battery indicator reaches low on the LR30

The LR30's suction motor draws significantly more current when airflow is restricted — a partially blocked filter or tangled brush roll raises motor current draw well above the rated load. That spike causes voltage sag across the 4S Li-ion pack, and the BMS reads it as a low-voltage condition before the indicator has stepped down. The robot slows or reduces suction as a protective response, even though the battery itself still holds charge. Clean the filter and clear the brush roll before concluding the battery is at fault — a clean airpath drops motor draw back to rated current.

LR30 cuts out mid-clean and then restarts after a short pause

This cut-and-recover pattern is a BMS overcurrent trip, not a flat battery. When suction is sustained against a blockage — carpet fibres, debris jammed at the inlet, or a clogged filter — the motor holds a high-draw state long enough to trigger the BMS overcurrent threshold. The BMS disconnects the pack to protect the cells, the robot pauses, and once current demand drops the BMS resets and power returns. Clear the inlet blockage and check the filter condition. If the fault repeats on open hard floor with a clean filter, check resting pack voltage — it should read above 15.2V fully charged.
