Direct Replacement Battery

The Estry 14.4V 5200mAh lithium pack is built to the original specifications for Yeedi Vac 2 Pro, Vac 2, Vac and Vac Max robot vacuums. It restores the runtime lost to cell aging without changing the charging routine or docking behaviour.

Upgrade From Depleted Original

Swapping the factory cell makes sense when the robot no longer finishes a cleaning cycle or returns to base early. The 74.88Wh capacity matches the S10-Li-144-5200 part number, so the jump is worth it once run time drops below useful levels.

Fits Inside Existing Chassis

The pack measures 137.0 x 50.5 x 37.25mm and weighs 549.2g, sliding into the original battery bay without modification. Overcharge, over-discharge, over-voltage and short-circuit protection are built in, freeing the owner from external monitoring.

Questions about this item

What are the dimensions of the 137.0 x 50.5 x 37.25mm battery pack for the Yeedi Vac 2 Pro?

The replacement pack measures 137.0 x 50.5 x 37.25mm and weighs 549.2g, matching the original S10-Li-144-5200 form factor for the Vac 2 Pro and Vac Max robot vacuums.

How do you install the 14.4V lithium battery in the Yeedi Vac 2 Pro, and what step is often missed?

Power off the robot, remove the battery cover screws, unplug the old pack connector, connect the new 5200mAh pack firmly, replace the cover screws, then place the robot on the dock for a full initial charge before first use.

What maintenance does the 5200mAh lithium pack need, and when should it be replaced?

Keep the contacts clean, avoid storing the robot fully discharged, and run a full charge cycle at least every three months; replace the pack when run time drops significantly or the robot fails to hold a charge.
