whatever wrote:can i confirm something mentioned earlier, you can put an on/off switch on the negative wire to cell log to cut all power to it?
anyone done this?
That's the way I've been doing for more then a year with no problems. Some say there is still a slight power draw but it's very small if any.
yeah, I have a main on-off switch running to a relay that will interrupt the cell-log negative (turning it off).
I did some real-world testing w/ cell-level voltage readings, and my 20Ah pack would take something like 60 days to drain when left "off" and at about 65%-charge (storage charge).
And I think w/ everything left "on" it would take something like 6 days to drain. But I also have an alarm that would be triggered at LVC... so if you hear the alarm you know you screwed up and left the thing "on". I don't know what the exact #'s were since I did the calculation a while ago, but I do know I found no problem w/ that method of "turning off" the cell-logs.
