Logging battery Amps

[PaddyB]

Hello affinite,
as baltica-no9 writes you can go with you internal big shunt. but there is another problem to solve:
this chip measures only current and voltage, so you get only the power FROM the battery, if you want also to
measure the INPUT to the battery you will need another chip connected the other side around!

take an look to this swiss guy: https://www.youtube.com/watch?v=cG8moauf...reasSpiess

maybe better use an Hall Type sensor.

but try it and happy boating

The ina219 measures  both ways so oit will measure power going into the battery and out, but only current as it's connected to 0v.
