There are a couple of features that make the Victron more accurate than many of the cheap-o monitors:

For lithium, an important feature is automatic syncing - you can program into the Victron what your fully charged voltage and tail current is, thus when you know the battery is full, the monitor automatically syncs SOC to 100%. This compensates for integral errors, which are always an issue with Ah meters/coulomb counters.


The AiLi does this.

The AiLi I bought would only auto reset to 0% SOC when the battery goes below a certain voltage threshold. This is neither logical or useful.

AiLi Manual - see page 5

The snark and derision is unnecessary.

Actually you're setting your zero capacity voltage point rather than the full, but it's for the same purpose and of course your capacity.

“ The snark and derision is unnecessary.”??...Snark, How so ?? (apparently only when I use your same words??)..I really don’t get it - I guess I forgot to check the box for a ‘sensitivities waiver’...[emoticon]

3 tons, in the High NV Desert, where sensitivities are not a currency

Ignoring the bickering, resetting at zero SOC isn't useful. Most folks rarely run their battery down to 0% SOC as it greatly shortens the life (lead) or risks a BMS shutdown (lithium), and in general you want some reserve capacity (both). So in practice this does not actually do anything.

Well, for the record Sir I never once knocked your AiLi meter, and even stated that I was not familiar with it...But then (per your demand for ‘evidence’...) it was presumed to be incumbent on me to prove that Victron was any different that your Chinese made meter (huh??)...No doubt the Chinese have the ability to make good stuff, but owning a Victron, why should I care about comparing to a particular brand labeled AiLi, or any other brand??...There’s no need whatsoever to justify what works for you, in fact, having read the AiLi instruction link you’ve just provided, it says it’s suitable for Lithium so I take AiLi at their word, but you’d previously stated that it was strictly a coulomb counter, but that the error rate was only negligible - fair enough, but understand that I have no interest in disparaging the brand of your’s or anyone’s meter choice du jour..I did say for the broader audience that my former LinkLite had proven not compatible with LiFePO4, of which (for reasons unknown) you chose to casually dismiss as just a defective meter (Not!)...Seems (per your past pointed accusations) that you sought to call me out for ‘hidden reasons’, but it’s far better to just stick with tech matters, which is why we’re all here - JMHO

I didn't even know about the zero setting since I used the 100% setting when the battery was full and it works fine.
