Bosch Indego 800 Replacement Battery 32.4V 3000mAh Li-ion

Bosch Indego 800 / 1000 Series — 32.4V Li-ion Replacement Battery (F 016 L67 804)

This is a 32.4V 3000mAh Li-ion replacement battery for the Bosch Indego robotic lawn mower range. It fits the Indego 800, 850, 1000, and 1999 models, along with several other units in the same series. Voltage and cell configuration match the original F 016 L67 804 specification.

• Indego 800–1999 series compatibility: These models share the same 32.4V battery rail, connector pinout, and BMS handshake protocol. One battery covers the full range listed because Bosch carried the same pack architecture across the series without changing the interface.
• Bench tested on actual hardware: We ran this pack through the Indego charge cycle and confirmed the BMS handshake completes correctly. The charger accepted the pack, balanced the cells, and reached full charge without fault codes.
• Seasonal storage tip: Before the first mow 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's inrush current on a cold pack can trip the BMS before the mower completes its first row.

BMS cutoff on thick grass or wet-grass blade load

The Indego's blade motor draws significantly more current when cutting thick or wet grass. If that inrush spike exceeds the BMS current threshold — even briefly — the pack shuts down as a protection response. This is not a battery fault; it is the BMS doing its job. A new pack will behave the same way under the same conditions because the threshold is built into the cell protection circuit, not the battery age.

Li-ion cells that self-discharge below approximately 2.5V per cell over a long storage period will be refused by a standard charger — the charger reads the pack voltage as too low to accept a charge safely. Some Bosch Indego chargers enter a fault state and will not attempt recovery. If this happens with a replacement pack, confirm the pack resting voltage at the terminals before inserting it; a healthy new pack should read above 30V. If the charger still faults, try a 10-minute rest period after removing and reinserting the pack to allow the BMS to re-initialise.
