End absorb phase based on cumulative AH from shunt

Hi all,

Please forgive me if this question is already answered somewhere, so far I haven't found it.

It is possible in the current firmware to stop charging and go to float based on the cumulative AH that have returned/charged the battery? Is this possible with DVCC? I realize this would not be a perfect solution and would need to have a charge efficiency calculation applied but I'm just wondering if it's possible. This would be perfect for LiFePo4 situations where there is no CANbus communication with the CCGX/Venus GX.

I'm not currently a Victron user however I'm definitely considering for some future projects, especially if this is possible.

Thanks!

Hi,

Question: Why would you want to do that?

Because from what I know, the AH in and AH out is not a 100% exact science, using a BMV you get it very close to correct.

And batteries will keep on accepting amps, till they are full, which may be more or less than the calculated AH in/out.
