Vortech battery backup alternate
 

For those of you interested in making your own Vortech battery backup system...

I checked the local costs of a Battery Tender Junior - yipes, $50. Even online it'll still cost close to this with freight.
So I went to Canadian Tire. They had this charger on sale today for $19.99 http://www.canadiantire.ca/AST/brows....jsp?locale=en

And for a rechargeable battery, I went Battery World and picked up a 12v 18Ah sealed lead acid battery, much like this one http://www.mobilityexperts.co.uk/pro...ttery-12v-18ah , for $60.00

I grabbed a pair of EcoTech fused backup connectors from J&L.

I bought a pair of female connectors from RP Electronics in Vancouver.

I should be able to run both props @ 50% for 36 hours off this one battery.

If you can't get your hands on the factory cables for the battery ports on the pumps, you can use these 1.3mm x 3.5mm male connectors and a 2A fuse (per pump)

If anyone in Edmonton needs a battery. I have 8Ah 12v rechargeable batteries

Gregzz4,

Nice.

Please post photos of your DIY battery backup for your Vortechs.

Thanks!

This is all I have for now and you can't really see much :wink:

When there is a power outage the backup battery kicks in automatically?

Runtime is 36 hours at 50% with an 18Ah battery.

What was the approximate cost of the DIY battery build?

Thanks!

I'm not convinced about the 36 hour runtime - just what I got off the web.
We had an overnight outage and if I recall correctly, 12 hours brought the battery down by 50%. But that was with 2 MP10s running.

Costs are in the first post but are over 3 years old now.

I'm happy with the trickle charger. After 3 years I hooked the battery up to my car battery charger and it was @ 100% nearly instantly, so the little charger is doing it's job.

My little Canuck Tire trickle charger is still going strong, and my original battery purchased back in Dec 2011 is also still good.
Some time back in 2016 I purchased a second battery to double my run time.
This also allows me to overlap the original battery as it ages.
I connected both batteries' positive and negative posts together with 10ga wire, and connected the charger's positive to 1 battery, with the charger's negative connected to the other battery. This ensures both batteries receive a ballanced charge.
I also connected my MP10s to 1 battery's positive and the other battery's negative. This way the pumps draw from both batteries equally.

My run time for 2 pumps should be 72 hours @ 50%, but even if I only get 1 day it's enough.

I think, now that the original battery is 7 years old, I'll replace it soon.
