About this replacement
Landxcape CR208E / LX835 Series — 20V Li-ion Replacement Battery (LA0007)
This is a 20V 3400mAh (68Wh) Li-ion replacement battery for Landxcape cordless lawn mowers. It fits the CR208E, R800 Smart, LX835, LX992, and three additional models in the same platform family. The battery slots into the deck-mounted battery compartment and powers the cutting blade motor directly.
- CR208E, LX835, LX992 and R800 Smart platform: These models share the same 20V battery rail, connector pinout, and BMS communication protocol. One pack works across the full family without adapters or firmware changes.
- Bench tested on actual hardware: We ran this pack through full load cycles simulating blade motor inrush and sustained cutting draw. The BMS held trip thresholds correctly and cell voltage balanced within spec across all discharge stages.
- Seasonal storage tip: Before the first cut of the season, bring the battery indoors overnight if temperatures are below 10°C. Cold Li-ion cells carry higher internal resistance, and the blade motor's inrush current on startup can trip the BMS on a pack that hasn't warmed to room temperature.
BMS cutoff during thick-grass or wet-grass cutting
The blade motor on the CR208E draws a significant inrush current each time it hits a dense patch or wet clump. If the pack's cells are partly discharged, internal resistance rises and the BMS may read an over-current condition — cutting power mid-row. This isn't a faulty battery; it's the protection circuit doing its job. Start each session with a fully charged pack, and avoid mowing wet grass where possible. If the mower cuts out, stop, wait two minutes, and restart — the BMS resets once current drops below the trip threshold.
Charger showing fault light after winter garage storage
A battery left in an unheated garage over winter can self-discharge below the charger's acceptance voltage — typically under 14V on a 20V Li-ion pack. Most Landxcape chargers interpret this as a faulty or incompatible pack and flash a fault LED rather than starting a charge cycle. Move the battery indoors and let it sit at room temperature for two hours. Then connect the charger — once cells recover slightly above the acceptance threshold, the charger recognises the pack and begins the recovery charge normally.
