iHome iHRV2 Replacement Battery 14.4V 3400mAh Li-ion

iHome iHRV2 / Eclipse AutoVac / iHRV4-GRY — 14.4V Li-ion Replacement Battery

This is a 14.4V 3400mAh (48.96Wh) lithium-ion battery for the iHome iHRV2, Eclipse AutoVac, and iHRV4-GRY cordless handheld vacuums. All three models share the same 14.4V cell architecture and connector format, so one replacement covers the full range. When the original battery no longer holds a charge, suction power drops off early — this cell restores full motor voltage from the first run.

• iHRV2, Eclipse AutoVac, iHRV4-GRY compatibility: These models run the same 14.4V motor rail and use identical battery housings with the same BMS handshake protocol. A single cell fits all three without modification.
• Bench tested on actual hardware: We cycled this battery through discharge under a restricted-filter load condition to verify BMS response. The protection circuit held steady at rated voltage without tripping during sustained high-draw pulls.
• Dock charging on cordless vacuums: Do not leave this vacuum permanently on the charging dock. Continuous trickle charging accelerates capacity fade on Li-ion cells faster than periodic charge cycles. Charge to full, then remove the unit from the dock until the next use.

Suction dropping before the battery indicator reaches low

The iHRV2 motor draws significantly more current when the filter is partially blocked — this pushes the cell voltage down faster than the indicator circuit expects, so suction fades while the indicator still shows charge remaining. This is voltage sag under load, not a faulty battery. A clean filter returns the motor to its rated current draw and keeps cell voltage stable across the full discharge curve. Check and clean the filter before assuming the battery has failed.

Motor cutting out mid-clean and recovering after a pause

This is a BMS overcurrent trip. When sustained suction is restricted — usually a blocked filter or a clogged nozzle — the motor draws beyond the cell's rated discharge threshold, and the BMS cuts power to protect the cells. After a short pause, the BMS resets and the motor restarts. The fix is not a new battery. Clear the blockage, clean the filter, and confirm the nozzle path is unobstructed before running the vacuum again. If the trip repeats on a clear filter, check that the replacement cell's BMS threshold matches the motor's rated draw at 14.4V.
