Battery Backup for Basement Pumps

The Delta Hi-PowerMaxx provides battery backup for larger pumps such as the V4, V6, Foul and BespokeV3 basement pumps when there is a loss of mains power. If the pump loses power, the battery backup system kicks in and keeps the pump running (see spec for guidance on cycles per pump on the battery back up system). This allows the sump pumps to continue to safely discharging water from a basement even during a power cut.

How it works?

This battery backup is specifically designed to run one or two V4, V6, Foul and BespokeV3 basement pumps without mains power. When power fails, the pump(s) automatically take power from the Delta Hi-PowerMaxx. This battery backup will have been fully charged during mains operation. It will automatically recharge when mains power returns

How long does the battery last?

The Hi-PowerMaxx battery can run primary and secondary ground water and foul pumps without mains power for over 10 days depending on the number pumps and cycles per hour. It can sit in standby mode for at least 50 days and is virtually inaudible.


Installation is simple. Hi-PowerMaxx is free standing and can be installed in any dry ventilated area. As this unit is fitted in the power line, no additional electrical spurs are required.

Note: This unit is designed to power Delta V4, V6, Foul and BespokeV3 basement pumps. It is not suggested this unit is used with other manufacturers pump stations.
