  • Battery Test

    Posted by Art on June 20, 2020 at 10:11 am

    Turned on the refer yesterday morning, Later in the day I loaded with frozen meat from house, I loaded refer with 3 gallons of water some beer and some other goodies. This morning at 7:00 am I went into bus refer up to temp battery switch on, water pump switch on, took this screen shot of Victron monitor readings.Un plugged bus, I will watch it through the day and see how it goes. Last time we dry camped at beach, with 22 year old Whirlool refer old Freedom inverters and a few led’s, Now with 1 year old Whirlpool refer-Magnum 2812 inverters and all led’s I think I set the Magnum inverter’s cut out at 12v does that sound about right??

    Auto gen start should be 12 volts . Inverter cut out is usually 10.5 to 11 volts

    are you sure your BMV settings are configured correctly, and its gone through a few cycles ? is this the first time you’ve used the SOC bmv ? because there is no way its 13.16 at 100% and 97% at 12.61. . i mean there might be if your tail current setting just happens to land at 12.63 or somehing. . which would be pretty rare because lithiums are 13.5v and AGM are 12.8

    13.16 was still plugged in. Now after 8 hours 12.58v 94% And remember we are not in the bus, It’s parked inside Refer is on nothing else, refer is cold ice box O degrees refer 28 degrees not mush else using power. Trying to simulate bed time. Usually 1st thing or 2nd thing run gen for 1 1/2 hours or so and same before bed, Like I said before with old refer and inverters next morning the old inverter shut off from lack of power.

    End of test 5:45 pm 10 hrs 15 min 93% 12.55 volts just plugged it back in.

    looking at the used amp hours on Victron it makes since starts 4 hours -42.6AH 8 hours -88.3AH 10.25 hours -110AH I noticed when compressor was running the time remaining was less, When compressor shut off the time remaining went up. Interesting new refer and inverters made a big difference.
