Battborg: Powering a Raspberry Pi from Batteries for 14 hours and 30 minutes

Powering the Raspberry Pi from batteries for 14 hours and 30 minutes!

This time lapse video was taken with a Contour+2 on one shot per 30 seconds picture mode, which gave approximately 1750 images.

The battery pack consists of 8x GP2700 rechargeable AA batteries. It's powering a Raspberry Pi model B+

In this test it lasted approximately 14 hrs 30 minutes. The screensaver runs at approx 22FPS and has an approximate load of 15% on the Raspberry Pi.

How do you detect when batteries are almost dead so you can safely power off the raspberry pi?

[MidnightMarrow]

I build drones and have some beastly LiPo's that I thought about throwing on a Pi haha.

And is this powerful enough to power a 7 inch screen connected to the raspberry pi 3?

[joshandroid]

Does it work on Raspberry Pi 4 model 4GB RAM? Greetings from Chile. Sorry for my bad English.

[marcoscaixetasousa]

Does it possible to monitor battery voltage to see charge level?

[blizzred]

Will using bigger batteries like D or C make it last longer?

[Guram_Zhgamadze]

Is there any way to attach solar panel to charge this batteries? I want to get 24h nonstop Raspberry pi

[freemanfreed]

what will happen if I plug the raspberry pi to a computer via USB to access the desktop and then power it by a external Battery or power bank ?

[RecallReviews]

How can I Install an on off switch via soldered wiring connected to the switch itself.

[luisnavarro]

does the pi auto shuts down when the battery dies?

[Milan]

Question - and two battery holder or bigger version?+ 7´´ display?Recharger?Connect rpi or board to the power and charge batteries?Where i buy solar panel for charging batteries?

[nogost]

the batteries can be coneccted in series?

[akmason]

I have a question The BattBorg As an output of 5 V at 1.5A don’t most raspberry pi need at least 2.5 A

[Prizzly]

are you going to test this on raspberry pi 2 b? what is the actual output A?

[ryansweet]

If I buy the soldered board only would I be able to change the AA Batteries for two 9 volt batteries instead?

[ShyamPrasadVAtri]

I want to buy this but have a question
1. Can I use 9v input insted of 12v?
2.Is it available in USA? through amazon?? because shipping will take long time

[MrBobWareham]

I understood that a Pi 3 needs a minimum or 5v 2 amps to work properly as recommended by the Pi foundation?
If that is wrong then why is the power supply 2 amps thanks for any information Bob

[Mrvideosandgames]

Looks good… I kind of want one but don't think I'd use it. Oh, what to do? :S

[BryanSeigneur]

I see those AAs are rechargeable. Are they lithium? Lithium has longer lifetime than anything. And how much are rechargeable AAs? I've got spare 18650s laying around scavenged from laptops. They're sold for vaporizers, power banks, even cars and grid storage. So, the world is full of them for the scavenging. It's practically a maker's duty to pull up some of the slack in supply. I'm just concerned about the continuation of old battery chemistries that don't last as long, and formats that aren't common. Those both mean more waste and wasted energy in the recycle process than longer-lasting chemistries (lithium), and common formats (18650) for that chemistry.

How long would you say this would last whilst using a RPi model 2 running a camera module and wifi dongle?
