What's Everyone's Battery Life?

On my first GBZ I used Popcorn's red LED connection. I have the components to do the diode monitor for my next two (not started yet).

Couple of things. With your current setup you can tweak the python script and get a little longer before it shuts down. Maybe 1/2 hour, I find popcorns script is a little conservative by shutting down when red led is on after 10 seconds.

Also keep in mind that cambles LBO circuit does not give you low battery warning video, it shuts down when battery low level is reached.

I actually tweaked the script a bit, too. Instead of the battery warning when the LED is on for 10% of the 10sec polling interval, I think I set it to 50%.

Good to know about no warning before the 60 second shutdown alert on the diode. I hadn't really looked into the differences yet. Maybe I'll stick with the the LED monitor then.

I think I went with 25 seconds and 30% on mine which worked quite well for me. Just have to experiment.

Low battery video may not be a big deal for some but just so you were aware.

I personally think the lack of low battery video thing is a big deal. Can we try and get one that has it on camble's modified script? I'm gonna try and get an LED set up but if not the video is the only thing I would have to know where the battery is at...

@Ganreizu the problem is not the script, infact he did not modify popcorns script in that regard. The problem is when the LBO pin is used as in his circuit the signal is either high or low. So when it goes low then game over pi shuts down. You could still use his circuit and wire the low battery part as popcorn did. The script will still work.

I too enjoy having a warning indicator that gives me more warning than just a cold shut down.

Here in the UK, the highest mAh value battery I could find that was the right dimensions was 2000mAh, the customer services from the place I bought it from advised that I could connect 2 of them in parallel to get double the capacity, has anyone tried this? I'm not quite sure how to do that safely, also are you guys using balance chargers to charge your LiPos?

Paralleling 2 Batteries is fairly easy. Basically, you are combining the leads of 2 batteries into one connection. There are multiple ways to do this. The easiest is to make a parallel harness. You will need 2 female connectors (Batteries, plug into these), and one Male connector. Solder a single positive wire onto the positive side of each female connector. Repeat for the negative. On the male connector, solder both Positive Wires to the positive side of the connector. Repeat for the negative side. You will end up with 2 positive, and Negative wires going into the one Male Connection. This keeps your 3.7v, but adds the mAh of both batteries together (Multiplies the Capacity, not the voltage).

Balance Charging Single Cell lipos is not needed in this case. When you run Lipo Batteries in Series (Multiplying the Voltage, not the Capacity), balance charging the cells is highly recommended. Note; You can create a harness for series as well. I will not put that information in this post as to not add confussion.
