The pumps for the two tanks I want to put a backup on are not sold anymore so I do not have the specs. There 24V only but not sure on there allowed range. The watts is something i'll need to get a direct reading with a shunt or a meter.

So the pump has 24 volts supply, no details are given on its supported voltage range. Its one of these newer generation pumps where it uses DC and a PWM to generate 3 phases which rotate the integrated pump and fixed magnetic rotor. Do I use a fix voltage power supply to charge the cells ? Will...

It still comes down for me at least I need these questions answered. I'm sure that these will lead to other questions.

Good idea, its not as if I need the pump to have its power maintained during the switch over like you would for a computer.

So the question for me is if I have a pack which can generate 24 volts what are the following. 1. what is its max voltage ? 2. what is the min voltage ? 3. what voltage would I need to charge / keep the battery charged ? 4. is the max voltage a problem for the pump ?

Correct, there are options to purchase battery packs for pumps but your paying for someone else's time and I really would like to understand the problem.

That's for this, interesting products. I'm really wanting to understand the rules so I can create my own. Because I have more than one tank and want to keep the costs down.

Hi All We had a power outage to day which lasted a little too long and I had fish die. If I had been home I would have wired the generator. The pump is powered by a 24V DC power supply, how could I put a LiFePO4 battery between this the power supply the the pump controller. The issue for me is...
