How to use Battery Backup? #39

Open nipunbatra opened 11 years ago

nipunbatra commented 11 years ago

Did it come with some manual? Both the battery backups weren't able to run RPi. I connected mains to the backup and from backup took a cable to RPi. Didn't work with both. Since i had been sorting other issues first, had not talked about this. Since electricity failure is extremely common these days, it would be important to know how to get this thing to work.

@amarjeet-iiitd , @manojgulati : Did it work for you in the lab?

Nipun i haven't tested it. Please consult sir regarding this.

amarjeet-iiitd commented 11 years ago

I think it can only do one thing at a time - either charge or discharge. So you probably have to remove charger from main supply and RPi should then run. And then after 1-2 days you have to again charge it while keeping RPi on main for that time.

One of the two battery backup does not have the capability to charge and discharge simultaneously. It might be tricky to know when its battery may die.

The other one can charge/discharge simultaneously but not enough current to power RPi. As of now the situation remains as earlier- at the mercy of electricity!

Try charging the bigger battery completely and running RPi out of it. See how long RPi may last. We may then want to optimize RPi stuff to keep WiFi off for most time and save power at a later stage.

We are not using WiFi on that RPi, so that shouldn't be a problem. @manojgulati: Can you try chanrging battery completely and see how long it runs?
