I have made a battery backup system for my 24V Jebao Pump (DCP-15000).
This pump has a low voltage protection built-in to it, so supplying it with 12v will not work with these pumps.
So I have designed a battery backup system that is fairly simple, and works great!
It's designed to have no battery leakage while charging, so no need to worry about your battery draining slowly while the mains power is in use.
I have tested this, and it works perfect with no issues.
Here's the parts list:
- Battery Charger - https://www.amazon.com/gp/product/B07CZ7KWP3/
- 12V AGM Battery - https://www.amazon.com/gp/product/B07TG7PJ41/
- 12V to 24V Boost Converter - https://www.amazon.com/gp/product/B018XBH2GW/
- 24V DC 4PDT Relay - https://www.amazon.com/gp/product/B00DN34ON0/
- True 18 AWG Pigtails - https://www.amazon.com/gp/product/B072BXB2Y8/
Here's the schematics:
To make it super easy, I listed which pin number on the Relay each wire goes to.
The relay has the pin # printed next to each terminal.
For example, the ground wire from the Pumps Power Supply goes to both Pin 13 & 7 on the relay.
The positive wire from the pumps power supply goes to both Pin 14 & 8 on the relay.
Just follow the pin numbers on the schematics.
