Battery backup

HippieSmell · 12/02/2017, 01:17 PM

If the pump is 24 volt, like the 6150, does it need connecting to a 24 volt battery? Or, if I connect to a 12 volt battery will it just run at half speed?

For backup you will generally just use 12V and the pump will run at half speed, the 6150 needs a minimum of 12V so the battery should be a fairly strong fully charged battery, typically a good SLA battery fully charged is 13.2-13.4V

Thanks. Do you think two batteries wired in series to get 24v would be better? As in less likely to suffer voltage drop and not work?

What is the max voltage for the 6150?

24, it will take up to 28 before it is possibly damaged.

The problem with 24V for backup is keeping the batteries charged gets complicated and expensive. We generally just need enough flow to keep things alive and 12V will suffice, my comments about battery charge were mainly because the regular DC streams can run on 10 and the smallest nano streams 8, the 6150 won't run below 12 so battery choice becomes an issue, I wouldn't use for example a lantern battery.
