Zanshin I Battery Monitor

Link10 Battery Monitor The Link 10 battery monitor was one of the most important devices aboard and I used it several times daily to see the state of charge (as can be seen by the wear and tear on the "Select&qout; button. Here it shows that 151.1 Amp Hours have been removed from the batteries.

After installing all those extra batteries and beefing up the recharging capabilities of the system as well as the big inverter so that I can make my beloved espresso, the final component that I needed was some way of actually monitoring the state of charge, the remaining amp-hours in the battery bank as well as seeing what the current consumption is.

The Link 10 is a small and deceptively simple looking device which is hooked up to the battery using a large shunt directly at the battery. This allows one to measure all of the electricity going into the batteries during charging (or via the wind generator) and the power drain coming out. It measures the actual voltage and uses internal logic to compute the real state of charge in the battery bank; this isn't as straightforward as it would seem, just take a look at Peukert's Law to get an idea of what this can entail.

I had convinced Barry that he needed a battery monitor for Solitaire when he was equipping her and he purchased the last available BVI unit. I was going to wait until St. Martin to get the more advanced model, the Link20, which can monitor 2 battery banks simultaneously, but Barry decided that he didn't really need to know all that much about the state of his batteries and I bought his Link 10 (at a discount since it was now a used model). As is always the case on boats, what seemed to be an easy and straightforward installation ended up taking most of 2 days to complete but once I finally had the system installed and all the fuses replaced I was surprised at how accurate and useful this little device really is. I can recommend it highly to anyone with a DC powered electrical system.

The picture above shows the Link10 in in “Amp Hours Used” mode, showing that I have used 151.1 Amp hours from the fully charged state of the batteries. This is after 3 days with just a short 2 mile motoring stretch to recharge. The rest has come from the wind generator and I think that the consumption is more than fair considering that I have the fridge running, the inverter in use for the notebook as well as for coffee, and other minor drains. I will need to replace my bedroom fan with a Hella to further reduce drain, as I think that running the fan at night as well as using a conventional anchor light instead of an LED one are also major constant drain sources.
