Redmond RV-R100 Replacement Battery 10.8V 2600mAh Li-ion

Redmond RV-R100 — 10.8V Li-ion Replacement Battery (SUN-INTE-321)

This 10.8V, 2600mAh Li-ion battery is a direct replacement for the Redmond RV-R100 robotic vacuum cleaner. It powers the drive motors, suction fan, and onboard navigation system. When the original cell degrades past the BMS cutoff threshold, cleaning runs shorten noticeably — this cell restores full operating voltage to the platform.

• RV-R100 platform fit: The RV-R100 uses a 10.8V nominal Li-ion pack with a specific connector and BMS handshake. This cell matches that voltage rail and communication protocol so the vacuum's charge controller recognises and accepts the pack correctly.
• Bench tested on actual hardware: We cycled this pack through charge and discharge sequences, confirming the BMS reports state-of-charge accurately to the vacuum's onboard firmware and that overcurrent protection trips at the expected threshold under a simulated motor-start load.
• Dock charging discipline on the RV-R100: Do not leave the RV-R100 sitting on its charging dock continuously between uses. This vacuum's dock delivers a trickle charge indefinitely, and sustained trickle current accelerates capacity fade in Li-ion cells. Charge to full, then remove the unit from the dock until the next scheduled clean.

Suction dropping before the RV-R100 battery indicator reaches low

The RV-R100's BMS monitors cell voltage under load, not just at rest. When the filter is partially blocked or the brush roll is restricted, the suction motor draws above its rated current and the cell voltage sags sharply. The onboard firmware interprets this voltage sag as a near-depleted pack and reduces motor speed to protect the cell — even if the indicator still shows charge remaining. Clear the filter and brush roll first; if sag persists on a clean machine, the cell has likely degraded below 2,400mAh effective capacity and needs replacement.

RV-R100 motor cuts out mid-run then recovers after a short pause

This is a BMS overcurrent trip, not a firmware fault. When the brush roll hits a carpet edge or a debris blockage causes sustained high motor draw, the BMS cuts pack output to protect the cells. The unit pauses, the BMS resets after a few seconds, and operation resumes. If trips happen repeatedly on normal surfaces, check the filter — a clogged filter forces the motor to work harder than its rated draw on every pass, triggering trips that would not occur with a clean filter and a fresh cell at full voltage.
