DIY Jebao 24V Battery Backup

[theatrus]

Yes, unfortunately there isn’t. I run two pumps in parallel, both at the “40” setting. The battery only goes into one, so I achieve the same end result as an Ecotech in backup mode.

Two of the Jebao pumps are still cheaper than one of the Ecotech pumps, so I guess it tips the balance in my case.

Nothing wrong with that :)

I do wonder at what voltage threshold the Jebao would stop working - torque and power should go down as voltage drops, but its no good if the pump stops or won't start.
