Another Q on Victron (battery monitor)

[MapisM]

Does anyone know WHICH capacity number does the Victron battery monitor (BMV-700) expects to be feeded with?
The manual just explains how to set the capacity of the battery bank in Ah, but doesn't specify whether it's expecting the 5 or the 20-Hr rate.
Or anything else for that matter, though I suppose it's either the 5 or 20 which are the most commonly used...
Thanks in advance!

I used 20 hour rate for my 2 x 260Ah 6V Trojans.

Many thanks. T-145 batteries, I suppose?
I also considered them, but couldn't justify a 60% price difference for a 15% higher capacity vs. the 225Ah T-105, so that's what I went for.
Besides, I also suppose that you have them connected in series, and you used 260Ah as a setting, which is what you've got at 12V, right?
And last but not least, if you don't mind me asking, did you use the 20-Hr rate because you found it specified somewhere, or just because you guessed that the most commonly used number was bound to be the right one?

Yep T-145, agreed there was a set up in price but with no generator I wanted as much Ah as I could physically fit in.

I calculated the loads and they were close to the 20-Hr discharge rate, so it seemed the logical one to use. Not sure if my logic is correct though.

Manual is on the boat in Spain, but I recall that is does state somewhere in there to use the 20 hr rate.

My current one is monitoring 2 x 230 amp hour batteries and working well.

Interesting, I'm pretty sure that in my downloaded PDF manual it isn't specified
Funny that they made a different printed version... Is also yours a BMV-700?
