Anyone know of a battery backup solution for these? or really any DC return pump? I think vortech has something for theirs but like all of their stuff $$$$...


I'm going to get a 100aH AGM 12v deep cycle battery to run my two gyre pumps in low voltage mode off my wave engine but was also thinking about return pump (yes I know its not REALLY necessary)

I'm using the circuit board out of one of my Ice Cap G1 batteries (battery is dead) to tie the larger battery to it.

However the return pumps are anywhere from 24vdc to 48vdc and much more current.

I think the Varios is 36v and maxspect jumps are 24v. So was going to try and figure out how to hook up a battery backup to one.

I was thinking a dc-dc booster to get to correct voltage along with a diode similar to above to prevent pump power supply from feeding the booster and battery.

24V

Other issue I think is going to be battery longevity with these higher power return pumps.

At 70w/36v that is around 1.9A for varios 6 and 90w/24v is around 3.75A for the mj-dc8k maxspect pump.

Let me know if you are aware of other options or have implemented something similar.

I just have the wave engine. It runs 4 maxspect gyres and I have the battery cables.

I wasn’t planning on hooking the return pump to the wave engine since all 4 direct drive ports are used. Although I may be able to signal off the 0-10v but that still uses return pumps power supply.

Just not sure how to run a battery backup for return pumps ( other than vectra).

I wasn’t aware they had a forum... I will check over there tomorrow.

I have a 12v-24v 480w step up converter on my icecap 12v backup battery unit to power the Current eFlux main pump. I also added a pair of 12v 35ah sealed gel batteries to the system as well. The last thing I added was 24v diodes after the power bricks of the pumps to prevent the battery backup from pushing power back into the bricks. That way 100% of the battery reserve is used for the pumps and none is lost powering the bricks. This setup functions flawlessly and will power the main pump and pair of Jebao powerheads for about 50 hours at 35% main pump speed and 50% on the powerheads. This is after the UPS unit shuts down that will power the pumps for about 480 minutes until its internal batteries run out of power.

For charging the batteries I just use a standard 12v 5 amp battery charger/tender unit.

With this setup I know the pumps will continue to run even if I cannot make it home for several hours to get the generator online in the event of an extended outage.

@steveb Want another 12v deep cycle battery? My mom visited and I took the lead acid house battery off her RV and replaced it with lithium, so I have a deep cycle battery just sitting in my garage now.
