Currently we only have the control panel lights, (13.0V, 12.5V. 12.0V, 11.5V, <11.5V) to show the leisure battery condition. I don’t want anything fancy, it would be good to know how much energy is going in, from vehicle alternator and solar panel, and how much is coming out. Considering two of these, one to measure charge, one to measure discharge.

Simple and inexpensive, you can get 2 for £23 on ebay. At the start of a trip I would ensure batteries are fully charged on EHU, reset the ‘energy’ reading on both meters and then keep an eye on the readings to make sure they are balanced, ideally more going in than coming out. Can convert the Wh reading to Ah, using formulae (Wh)/(V) =(Ah) to calculate battery Ah remaining from original, although there will be some inaccuracy due to voltage change from 12 to 13 volts as battery discharges.
Even simpler would be a more precise voltmeter to measure the battery voltage to get the state of charge as below. Measured with a small constant load, e.g. a light on.
Thoughts from our resident experts appreciated.
thanks
