Wiper C Xe 25.2V 3400mAh Lawn Mower Compatible Battery 7030DE0

Wiper C Xe / Ciiky XE Series — 25.2V Li-ion Replacement Battery (7030DE0)

This is a 25.2V 3400mAh Li-ion replacement battery for the Wiper C Xe, Ciiky XE, Ciiky XH, J Xe, and related cordless lawn mower models. It matches the OEM part number 7030DE0 and slots into the same battery bay as the original pack. Voltage and capacity are drawn from verified product data — 85.68Wh total energy.

• C Xe and Ciiky platform compatibility: These models share a common 25.2V battery architecture, the same physical connector, and the same BMS handshake protocol. A pack built to the 7030DE0 spec communicates correctly with the mower's power management circuit across all listed variants.
• Bench tested on actual hardware: We ran this pack through full charge-discharge cycles and simulated blade-motor inrush load. The BMS held cutoff thresholds within spec and recovered cleanly after high-draw events without latching into fault state.
• Seasonal storage before first spring use: If the mower and battery sat through winter, bring the pack indoors overnight before the first cut. Below 10°C, Li-ion internal resistance climbs sharply — the blade motor's inrush current on a cold pack can trip the BMS before the first row is finished.

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

The blade motor on the C Xe draws significantly more current when cutting dense or wet grass than during normal dry-lawn passes. If the BMS reads a sustained current spike above its protection threshold — typically triggered within the first few seconds of a heavy-load row — it will cut power to protect the cells. This is not a battery fault; it is the protection circuit working as intended. Let the mower sit for five minutes, then resume at a slightly slower walking pace to keep draw within the BMS window.

Charger rejecting the pack after winter garage storage

Li-ion cells that self-discharge below roughly 2.5V per cell over a long storage period will read as outside the charger's acceptance voltage window — the charger shows a fault light and refuses to begin a charge cycle. The pack is not necessarily dead. Place it on the charger for 10–15 minutes anyway; some chargers will attempt a trickle-recovery pulse once the pack warms slightly. If the charger still faults after 20 minutes at room temperature (above 15°C), the cells have discharged too far for safe recovery and the pack needs replacing.
