Hello,
I'm using the Xantrex LinkLite as a battery monitor in a project, link below:
http://www.xantrex.com/power-products/power-accessories/linklite-battery-monitor.aspx
Got everything working fine but for some reason it seems to be drawing way too high of a passive current draw. The datasheet says 7ma passive draw, but when I left it on over the weekend it went from 100% to 90.5% in 3 days. That is with a 35Ah battery. So it thinks (not sure if I believe it really did) drained about 3 amps in 72 hours. Well that doesn't seem like it makes sense. That would make the passive draw 41.6 mA?
The monitor has always said it was draining at -0.1A when simply attached to the battery and nothing else. I assumed it was just saying that because it was accounting for itself and telling me it was draining some amount, but now I'm wondering if it thinks its draining over -0.05A and rounding it to -0.1A for some reason?
Anyone have any ideas?
The main issue is that this is going to be installed on a system where I won't have control over, but a customer/user. I found out the hard way that I have to keep power on to this guy even when the main switch is turned off because when this battery monitor looses power and comes back it needs to re-sync itself which requires either it being recharged or pushing a manual button to tell it its full charge. I was hoping the passive draw of this thing would be small enough the system could go months without monitoring, but at this rate the battery won't last much more than a month or so before the passive draw kills it.
