About this replacement
Bosch Indego 800 / 1000 Series — 32.4V Li-ion Replacement Battery (F 016 L67 804)
This is a 32.4V 5000mAh (162Wh) Li-ion replacement battery for the Bosch Indego robotic lawn mower range. It fits the Indego 800, 850, 1000, and 1999 series, among others. The battery powers the blade motor, drive wheels, and onboard navigation through the mower's full cutting cycle.
- Indego 800–1999 platform fit: These models share the same 32.4V battery architecture, connector pinout, and BMS communication protocol. One battery covers the full range without any adapter or wiring change.
- Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the Indego platform. The BMS handshake cleared on the first connection, cell balancing completed normally, and voltage held steady under simulated blade load.
- Cold-weather start care: Before the first mow 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 can trip the BMS on a pack that hasn't warmed to room temperature.
BMS cutoff during thick-grass or wet-grass blade load
When the Indego hits a dense or wet patch, blade motor current spikes hard — often 3–4× the normal draw. If the battery's BMS reads that spike as an overcurrent fault, it shuts the pack down to protect the cells. A new battery needs 3–5 full charge-discharge cycles before the BMS learns the load profile of your specific mower. Until then, keep the mower on shorter, drier grass so the motor current stays within the BMS acceptance window during conditioning.
Charger shows fault light after mower sat unused through winter
If the Indego sat in an unheated garage over winter, the pack may have self-discharged below the charger's acceptance voltage — typically around 25V on a 32.4V Li-ion pack. The charger sees the low cell voltage and refuses to initiate a full charge cycle, showing a red or flashing fault indicator. Place the battery in a 15–20°C room for two hours first. If the charger still won't accept it, check the pack's resting voltage with a multimeter — above 28V it should recover; below 24V the pack has likely over-discharged past recovery.
