Victron MultiPlus-II 48/3000 low voltage cut-out with LiTime ComFlex 48V


Are those the only two widgets available? Good to see min/max voltages. That's very helpful. Not all report this.

I have these:

You would think "battery consumed amphours" would be what I want, but I don't actually get any data there.

If you don't have this option, or it yields no data like mine, you might be able to create a custom widget or compute it from a data download.
 
So apparently the LiTime BMS does not consider "low draw" very well.. So here's what happens if you're letting batteries idle with minor load (<1 amp). Note, we go from about 85% SOC to 42% and then the whole thing shuts down.

I'll likely be moving to a Victron shunt, but the Litime BMS is designed for moderate or better loads. Totally inaccurate otherwise.

No one has ever said their system was worse off by installing a victron smart shunt.

The 300a (m8) is only $70, absolute killer deal and can track as low as .01A (but is better at .1a or more).
