Battery monitor

[sailaboutvic]

Suggestion please for a battery monitor that will give me a readout of charge and discharge in a timeline so I be able to see what the batteries are do at any time .
When I say readout I mean in a graft so I can see at any time what's happening , maybe some thing I can plug into a Laptop to give me a 24 hour timeline .
Battleries 300ah lead Acid sealed , solar charger MPPT , victron charger
Cheers

HI VIC,
Have a look at this. I fitted one when we left Aegina it has been brilliant. It tells me the SOC at a glance.

My CruzPro VAH65 Battery Monitor outputs V, I and Ah remaining in NMEA0183 format. I don't use this feature, but I suppose it could be logged and displayed on a PC if you're clever.
Other monitors might do similar. I don't know of one with built- in recording.

About the nearest thing I know of would be the Simarine Pico - https://www.simarine.net/product/pico-battery-monitor/

Exactly what I have, only I also have a victron mppt solar and I now have the bt dongle plugged to it instead...

Good monitor, but it doesn't do what Vic wants it to do.

The monitor combined with the Bluetooth dongle is supposed to give historical data

The Victron solar controller gives some useful history, but the history on the monitor is pitiful, useless.

Do I take it then with the lack of suggestion, the nothing on the market that will do what I want ?

Nearest off the shelf i've seen is the one PVB linked to in post #6

GHA has something running on a Pi that does what you want, not sure how easy it'd be for you to set up.

A possible (but somewhat complex) alternative.
