Hi reefers and #DIYwizards ,
I have been reading up on battery backup options for Nero pumps, and from what I can gather so far, there is none on the market at the moment because the pump driver for AI Nero pumps requires 24v and battery backups on the market only produce 12v. So what happen is the driver lits up, but pump doesn't work.
So I am trying to see whether I can do some DIY option with what I have. I don't know much about electrical wiring, so my apology in advance if questions I am asking are completely dumb.
I have an old coral box battery backup that I am thinking of reusing for wiring connections and fused protection that are already built in.
My plan:
1. I will replace the old 12v battery with 2 new and identical 12V 9Ah SLA batteries connected in series.
2. I will replace the original 12 v battery charger with a battery charger that can support up to 24v, like this one.
Questions.
1. The battery backup's existing circuit board and wires connections were designed for usage with 12v battery. Any potential issue if I use it with 24v battery (2 12v in series)?
2. Will charging 2 12v batteries connected in series with one 24v charger cause any issue down the line?
3. Fused protection built in for coral box battery backup should still work even if I increase the voltage to 24v, correct?
4. Any other potential issue you see with it?
Thanks in advance.
