    Vinyl Plank Flooring Installation Decision ???

    If the flooring wasn't enough 'fun', I am also installing backsplash tile. This is where the new oven will go. . . Prior to the tile was the range hood, which needed duct work to the outside. That slowed me down for a day or 2. I am at a point where I am assigning boat preparation duties to...

    LiFePO Batteries ???

    It's raining so the solar charging is a bust for the rest of the day. I hooked up the AC power and ran the inverter charging. It went into bulk mode for a few minutes (20 amps), then went into absorption mode . . . was pulling 1-2 amps. I'll see how things look in the AM.

    LiFePO Batteries ???

    Quick update . . . Yesterday, I let the new battery come down to a resting voltage, which it did after a while. 13.24 volts. Checking it again in the AM it was 13.22 volts. So, about 70% charge per the voltage chart. I decided to give it a few more % of charge and hooked the charger up for...

    LiFePO Batteries ???

    I'd like to put my boat under cover for the winter, but it stands a little over 12 ft high on the trailer. Maybe something to think about in the future. . I checked on the batteries after charging for about 2.5 hours (@ 20 amps) (13.48 volts). I'll have to see what the 'at rest' voltage...

    LiFePO Batteries ???

    My concern is that while the batteries are installed in the boat, it is supplying power (and small amounts of current) to the various systems throughout the boat. Mostly the inverter, but there is other stuff like CO detector and stereo keep-alive. So, even though there is some loss within the...

    LiFePO Batteries ???

    I’m not sure if all LFP batteries are the same, but . . . The cold protection in my batteries stops charging @ 32F, but the discharging keeps going until about 4F. So, with my boat, which has a lot of parasitic loads, the batteries run down.

    LiFePO Batteries ???

    Quick update . . . The defective battery is on its way back to LiTime and a new (presumably 3rd) battery should arrive later this week. The solar charging system that I made/installed last year is doing its thing.

    Should I buy a boat without a survey?

    What is wrong with this picture? $40K for a 20+ year old sailboat with a salvage title. Seems a little bit steep (OK, a lot steep) I suppose you are going to play a guessing game with us . . . So, my guess is that it is a Dragonfly. Would you care to tell us the length?

    LiFePO Batteries ???

    @cyclops222 . . . I have SLA batteries for the engines. The other loads are run on the LiFePO4 batteries. The main wiring feeds are 00 gauge.

    What kind of damage from an I/O in salt water for 2-3 years?

    As stated . . . (Bayliner) + (1991) + (I/O 2-3 years in salt water) = the concerns You would not only want to verify the condition of the outdrive, but also the condition of the boat's structure. You mentioned that you did not want to get into a structural restoration project, just purely...

    Vinyl Plank Flooring Installation Decision ???

    The refrige is in. . . . The new duct work for the range hood is proving to be a challenge . . . not much space up in the ceiling and wires in the way . . . :cautious:

    LiFePO Batteries ???

    I ordered another battery . . . Same as the others. Not sure how long the replacement will take and I did not want to start off the season with just 1 100 Ah battery for the 'house' loads. When I get the replacement, I'll work it in as a third battery, so I'll have 300 Ah of capacity on the...

    What kind of damage from an I/O in salt water for 2-3 years?

    Well, we don't know how new the boat is, or the brand of the engine/outdrive. . . which may help. As for the outdrive . . . I get about 3-4 months out of a set of anodes, then they are ready for the scrap bucket. You mentioned that the boat has been in the water for several years...

    LiFePO Batteries ???

    Yes, the battery appears to be dead. (I've tried a bunch of things) I'm thinking that the BMS did not protect the battery (cells) to the extent that it should have. The other battery (it's twin hooked in parallel) came to life with just a quick touch of the trickle charger. and was sitting at...

    LiFePO Batteries ???

    I've got the one sleeping battery sitting in the sun to see if a little more temperature will help wake it up. Otherwise, it my be going back to LiTime . . . :unsure:

    LiFePO Batteries ???

    Quick update . . . I had some trouble waking up the batteries . . . not sure if it is the charger or the battery. Anyway, I connected a trickle charger to the batteries . . . one woke right up and the other is still sleeping. Anyway . . . I got the Xantrex charging the good/awake battery...
