Bagotte BG600 Replacement Battery 14.4V 2600mAh H18650CH-4S1P

Bagotte BG600 / BG700 Series — 14.4V Li-ion Replacement Battery (H18650CH-4S1P)

This is a 14.4V, 2600mAh Li-ion battery pack for the Bagotte BG600, BG600 MAX, and BG700 robotic vacuum cleaners. It replaces OEM part H18650CH-4S1P and powers the drive motors and cleaning system. Capacity figures are taken directly from the product specification — 37.44Wh total energy.

• BG600 and BG700 platform fit: These models share the same 14.4V battery rail, connector pinout, and BMS handshake protocol, which is why a single pack covers the full range. Swapping between them does not require any firmware or charger changes.
• Bench tested on actual hardware: We cycled this pack through the BG600 charge and discharge loop under motor load. The BMS held the correct cutoff thresholds and the dock handshake completed without fault codes on every test run.
• Dock charging habit for this vacuum: Do not leave the BG600 sitting on its dock between cleaning sessions indefinitely. Continuous trickle charge from the dock degrades cell capacity faster than standard use cycles. Charge fully, then remove until the next run.

Suction dropping before the battery indicator reaches low

The BG600 motor draws significantly more current when the filter is partially blocked or the brush roll is restricted. That extra draw causes voltage to sag at the cell level before the indicator registers a low state. The vacuum interprets this as normal load and keeps running, but suction output falls noticeably. Clean the filter and check the brush roll for hair wrap — if suction recovers, the battery is not the cause.

Motor cutting out mid-cycle and restarting after a pause

This is a BMS overcurrent trip, not a power failure. When sustained suction restriction forces the motor to pull above the pack's rated discharge current, the BMS opens the circuit to protect the cells. The pack resets after the thermal and current conditions normalise — usually within 30 to 60 seconds. Clear the filter and inlet path, then restart the vacuum. If the trip recurs on a clean filter, verify the replacement pack's rated discharge current matches the H18650CH-4S1P specification before assuming a fault.
