EZIclean Aqua connect S200 Compatible Battery 14.4V 2600mAh

EZIclean Aqua connect S200 Series — 14.4V Li-ion Replacement Battery (INR18650-4S1P)

This 14.4V, 2600mAh lithium-ion battery replaces the original pack in the EZIclean Aqua connect S200, S250, X500, and X550 cordless wet and dry vacuum cleaners. It slots into the same battery bay and connects to the same BMS handshake points as the factory cell. Capacity is 2600mAh — matched to OEM spec.

• Aqua connect S200, S250, X500, X550 fit: These models share the same 14.4V battery rail, connector pinout, and BMS communication protocol. One battery pack covers the full Aqua connect range listed above without modification.
• Bench tested on actual hardware: We cycled this cell through the vacuum's motor start sequence and sustained suction load. The BMS held the discharge curve steady and triggered protection cutoff correctly at low-voltage threshold — no false trips under normal carpet-mode draw.
• Dock charging habit on the Aqua connect: Do not leave the vacuum sitting on the charging dock permanently. The Aqua connect's charger does not drop to a true maintenance float — continuous dock contact causes trickle charge stress that degrades cell capacity faster than normal cycling. Charge to full, then remove from the dock.

Cordless vacuum losing suction before the battery indicator reaches low

The Aqua connect's motor draws harder when airflow is restricted — a partially blocked filter forces higher current to maintain suction speed. That elevated draw causes voltage to sag at the cell terminals before the battery gauge registers low. The BMS reads the sag as a near-depleted pack and reduces output, so suction drops even though charge capacity remains. Clean the filter first — if suction restores immediately, the battery is not the fault.

Motor cuts out mid-clean then recovers after a short pause

This is a BMS overcurrent trip, not a dead battery. When the vacuum picks up a blockage or the filter is heavily loaded, instantaneous current spikes past the BMS protection threshold and the circuit opens. The pack recovers once current demand drops — typically within 10 to 30 seconds. Clear any blockage, check the filter for restriction, and restart. If trips continue on a clean filter with a new battery, test pack voltage at the terminals — a healthy cell at partial charge should read above 13.5V under no load.
