Power-G Easymow 28V 5000mAh Li-ion Replacement Battery

Power-G Easymow Series — 28V Li-ion Replacement Battery

This is a 28V, 5000mAh (140Wh) lithium-ion replacement battery for the Power-G Easymow, Easymow 6HD, and SF600 ECO cordless lawn mowers. It slots into the same battery bay and uses the same voltage rail as the original pack. When your factory battery no longer holds charge or capacity has dropped, this is the direct swap.

• Easymow, Easymow 6HD, and SF600 ECO compatibility: All three models run the same 28V platform with the same connector and BMS handshake protocol. One battery works across the range — no adapter required.
• Bench tested on actual hardware: We cycled this pack through repeated blade-motor load tests, including simulated thick-grass inrush draws. The BMS held stable across cycles and protection cutoffs triggered correctly at boundary conditions.
• Seasonal storage tip: Before putting the mower away for winter, charge the battery to around 50–60% rather than full. A fully charged Li-ion pack held at high state-of-charge for months accelerates cell degradation faster than a mid-charge storage level does.

BMS cutoff during thick-grass or wet-grass blade load

The blade motor on the Easymow draws a sharp inrush current every time it bites into dense or wet grass. If the battery pack is already warm from extended use, the BMS may read that spike as an overcurrent event and cut the output. This is a protective response — not a fault in the battery. Let the pack cool for five minutes, then resume. If cutoffs happen repeatedly on a fresh pack, check that the blade isn't dragging from a bent or dull edge, which increases motor load significantly.

Charger rejects pack after winter storage

Li-ion cells self-discharge slowly over months. If the pack dropped below approximately 2.5V per cell during storage, most chargers will refuse to begin a charge cycle — the BMS blocks it as a safety measure against damaged cells. Some chargers include a recovery or wake-up mode that applies a trickle current to bring cells back above the acceptance threshold. If yours does, run it. If the charger shows a solid fault light and no recovery option, the cells may have discharged too deeply for safe recovery.
