RedRoad V17 Cordless Vacuum Compatible Battery 25.2V CBH012-7S1P-SX

RedRoad V17 — 25.2V Li-ion Replacement Battery (CBH012-7S1P-SX)

This 25.2V 2500mAh Li-ion battery replaces the OEM pack in the RedRoad V17 cordless stick vacuum. It matches the original voltage rail and BMS communication profile for the V17 motor controller. Capacity is 2500mAh (63Wh), sourced to match factory spec.

• V17 motor voltage compatibility: The V17 motor controller expects a 25.2V (7S) lithium pack with a matched BMS handshake. A mismatched cell count or BMS profile causes the vacuum to refuse to start or cut out immediately under load. This pack uses the correct 7S1P configuration to satisfy that controller check.
• Bench tested on actual hardware: We ran this pack through the V17's full start-up sequence and sustained suction cycle. The BMS held steady through motor-start inrush current and maintained voltage above the low-cell cutoff threshold across a complete discharge cycle.
• Dock charging on the V17: Do not leave the V17 sitting on its charging dock permanently. Continuous trickle charge accelerates capacity fade in Li-ion packs faster than normal use cycles. Charge the battery to full, then remove the vacuum from the dock until you need it again.

Suction dropping before the battery indicator reaches low on the V17

This happens when the motor draws more current than the pack can deliver cleanly — voltage sags under load even though the indicator still reads mid-range. A partially blocked filter is the most common trigger: restricted airflow forces the motor to work harder, pulling current above the cell's sustained discharge rating. The BMS reads the resulting voltage dip as a low-cell event and throttles output. Clear the filter first, then check that the battery terminals are seated fully — a loose contact adds resistance and worsens the sag.

V17 motor cuts out mid-clean then restarts after a few seconds

This is a BMS overcurrent trip, not a dead battery. When suction is sustained against a blockage or a heavily loaded carpet, current draw spikes past the BMS protection threshold and the pack shuts output to protect the cells. The BMS resets automatically after a short thermal or timeout window — which is why the vacuum restarts on its own. To stop it recurring, check the filter and clear any partial blockages in the brush head before running again. If it trips immediately on a clean filter, measure pack voltage at rest — a healthy fully charged pack should read at or above 25.2V.
