Flymo Easielife Go 18V Replacement Battery 2500mAh

Flymo Easielife Go / Easilife Series — 18V Li-ion Replacement Battery

This 18V Li-ion battery replaces the original pack on the Flymo Easielife Go, Easilife 200, Easilife 350, and Easilife 500 cordless lawn mowers. Capacity is 2500mAh (45Wh). It slots directly into the mower's battery bay and connects to the same BMS handshake these models share across the range.

• Easilife series compatibility: The Easilife 200, 350, and 500 alongside the Easielife Go all run the same 18V cutting deck voltage rail and use the same battery connector and BMS communication protocol — one pack covers the full range.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the Easilife platform and confirmed the BMS handshake completed correctly, with cell balancing active across all cycles and no fault codes triggered on the charger.
• Spring start-up tip: Before first use of the season, bring the battery indoors overnight if temperatures are below 10°C — cold Li-ion cells have higher internal resistance and the blade motor inrush current can trip the BMS on a cold pack before a single row is cut.

BMS cutoff on thick-grass and wet-grass blade load

The Easilife's blade motor draws a sharp inrush current each time it bites into dense or wet grass. If the battery's state of charge is already low, the BMS reads that spike as an over-current event and cuts output to protect the cells. This is more common mid-pack — when charge is between 20% and 35% — than at a full charge. If the mower trips out during heavy growth, let the pack rest for five minutes and recharge before continuing rather than forcing another start.

Li-ion cells self-discharge slowly in storage. A pack left in an unheated garage from October to March can drop below 2.5V per cell — the threshold most chargers require before they will begin a standard charge cycle. The charger fault light does not always mean the pack is dead; it often means the cells are too low for the charger's acceptance circuit to engage. Try leaving the pack at room temperature for two hours, then reconnect — some chargers include a recovery or trickle mode that will engage once the pack warms. If the fault light clears and charging begins, allow a full charge before use.
