Direct Replacement Battery

The FYIOGXG lithium-ion pack fits Landroid S models WR102SI, WR103SI, WR104SI, WR105SI, WR106SI, WR110MI and WR115MI. It matches the original dimensions of 95.00 x 68.50 x 24.70 mm and includes a fully decoded chip so the mower recognises it immediately. No soldering or firmware updates are required.

Capacity and Voltage Match

The pack delivers 2500 mAh at 20.00 V, providing 50.00 Wh of energy. This exact capacity and voltage combination is the single figure that determines whether the mower will run for the expected cutting time on a single charge.

Sustained Discharge Behaviour

Under continuous cutting load the battery maintains a stable 3.7 V per cell until the protection circuit activates. The built-in safeguards prevent over-charge, over-discharge, over-voltage and short circuits, so repeated daily cycles do not degrade capacity prematurely.

Who This Is Not For

Owners of Landroid models not listed above, or mowers that require a different voltage or connector layout, cannot use this pack. It is also unsuitable for users who need a higher-capacity cell for extended run-time beyond the original specification.

Questions about this item

How long will the 2500 mAh capacity run my Landroid S on a single charge?

The 2500 mAh pack stores 50.00 Wh at 20.00 V, so actual mowing time depends on grass height, slope and the selected cutting schedule rather than the capacity figure alone.

Does the 20.00 V lithium-ion pack use a proprietary connector or a standard interface?

It uses the original Landroid S connector with a fully decoded chip, matching part numbers 50032492, 50032774, WA3230 and WA3231 for direct replacement.

Will the 95.00 x 68.50 x 24.70 mm battery fit inside the WR102SI battery compartment without modification?

Yes, those dimensions match the OEM pack exactly, so the replacement slides into the WR102SI, WR103SI, WR104SI, WR105SI, WR106SI, WR110MI and WR115MI compartments with no trimming required.
