Leds on Iota Battery Charger

Greetings,

I have installed a 55 amp Iota Battery Charger on my boat with the IQ4 controller. It has been on the trailer for the last year being painted and the batteries were deeply discharged. I plugged the battery charger in over the weekend for a couple of hours. When I unplugged the charger the led on the charger continued to blink. Is this normal? I am assuming that the charger is reading the voltage from the batteries and giving an indication of the charging regime that is applicable (bulk, float, etc.).

Do you think this process consumes much battery power. I have wired the charger directly to the batteries so there is not currently a way to disconnect it.

Your thoughts would be appreciated.

You are correct about the blinking. The blinking will stop and go to steady ON when the charging cycle has come down to float level. The led is not going to run your battery down if you charge the battery every month or so. Nice charger, I have same one and am pleased. I strongly encourage you to let the charger run its full cycle at least once a month to keep battery up to full charge. Iota chargers take more than a couple hours to go thru all 3 stages.

It's normal and, no, it doesn't consume much battery power.

When you say "I wired the charger directly to the batteries", I hope you have a proper size fuse or breaker installed near the battery. A 70A Maxi fuse or an 80A ANL fuse would be appropriate for that charger.

Btrayfors,

I have a 10 inch power wire between the Iota charger and an always-on power bus to which the bilge pump is also connected. The always on bus is connected to the hot side of the battery 1 terminal of the 2 way battery switch. Based on advice I have received from this forum I no longer use a second battery bank.

The charger power wire wire is not fused today. The bilge pump power line is fused as part of the bilge pump switch. It is my intention to add a fuse at the battery for the battery cable to the battery switch, would this adequately protect the charger wiring as well, give that it is just a couple of feet upstream from the battery?

Yes, that should do it, assuming you size it right. The 70A or 80A fuse size should be more than enough for your bilge pump and "always on" appliances, unless you've got something humongous attached (like a starter motor).

It goes everything correctly. 70A or 80A fuse should be more than sufficient to open the bilge pump and Equipment forever, unless you have something connected to a humongous.
