Battery Backup

[GDog3]

I ordered the battery backup unit (BBU) to power the ONT and EE Smart Hub Pro.

Problem is that it powers the ONT, but as soon as I plug in the Smart Hub it flashes red and shuts down power to both.

My Hub is the Smart Hub Pro 7. Anyone know if this is supported?

Wait time for support is currently over one hour.

@GDog3 Yes it is supported, correct BBU and correct cable to match the EE Smart Hub Pro version, just try the units individually to see which has the issue with current draw. 1st the ONT it takes very little current, then try the Pro it will draw a lot more, then finally them together, and assume you have the batteries fully charged on the BBU unit.

Many thanks Jim

i tried your suggestion but it didn’t work. Maybe I have a faulty one. 
ill call EE

@GDog3 That is all you can do, The two parts as below so you see the BBU and the cable for the ONT/Pro hub.

Thanks Jim

New BBU being sent out. See if that works.

@GDog3 Look carefully at the power connector for your PSU and the one on the cable supplied with your new BBU, those plugs are three pin type so not easy to test like the other two units, but the supply is still 12V D.C. for the Pro Hub. Hopefully it is just a bad BBU that has been sent and it's shutting down due to the current draw on itself.

Thanks Jim

The plug that goes to the Pro Hub does seem a bit of a snug fit. Maybe that is the issue. I'll report back when the new one arrives.

[JimM11]

@GDog3 Yes the Pro hub is the odd ball connector that is in use, and there are three connector cables in use by EE, one to cover the 6+, one for the BT SH2, and the final for yours the 7 Pro version.

Have never seen a Pro live to look at so would be worth you taking the look see for your original connector to what EE sends with the BBU. The 7 Pro is the most powerful for current draw due to the mass frequency supported and it's power brick PSU standard socket connecter is rated 48W with a 4A current draw whilst all the others are 50% off that rating. You for sure are the first to post as using but by now others must have tried it on a 7 Pro hub but it does appear the BBU is protecting itself from what you describe as happening. The only other thought is the new cable has the polarity flipped by mistake and if so just be careful when connecting it back up again.

Thanks Jim

Not a very good pic sorry. I can't tell at the moment what exact version it is. I'll look tomorrow if there are any clues on it.

@GDog3 Does look like the EE one from the link above.
