[beagleboard] Any battery cape alternatives?

Alternatively, you could connect a lithium rechargeable to the PMIC
header if you solder on the header on the black (or use P6 on a white)
instead of using the battery cape, if that's of interest to you. The
PMIC will charge the battery when plugged in and discharge when no
external power is available.

I run a 0.9 Ah 3.7 V lithium rechargeable on white bones with no issue
but I do not use USB.

You replied to only me, I'm replying to you and the beagle list.

Is that complicated? I'm a total newbie. But the Batterycap looks
like a rip-off, for what it actually does.
Can't I use something like this for what you suggest?:

I also look for an alternative screen.

It's not complicated as long as you read the bone SRM and understand
what the battery is doing.

The battery cape is expensive, yes. I assume the volumes are quite low
compared to the bone itself, thus the expense. Not many people run
bones on batteries.

I have no idea if that battery holder will do what I suggested. For
example, I use a UltraLife battery [1] on my bones. Cost is quite
reasonable (< $15 in 1 unit is possible to find).

Are there only 2 Pins to solder? Did you solder it permamently?

Are the requirements



3.0 to 4.2V



Kapzität 900mAh ?

For the black, you should solder all 4 of the PMIC header pins on. For
the white the header is already there. Soldering the header on
permanently is recommended for the black but you can simply jumper over
the battery with jumper wires once you have a header. To trick the PMIC
into thinking you have an NTC temperature reading, either get an NTC
and do it properly or cheat the sense by wiring a 10k resistor from the
temp pin to ground.

3.0 to 4.2V

Basically, yes. Most any < 2 Ah 3.7 V nominal lithium battery should
work. Get the specs off the one I mentioned and look for something
similar local to you.

Sorry, I don't use a screen.
