    LiFePO Batteries ???

    Back at the boat . . . looks like rain in the forecast for the next few days. I got the component panel wired up . . . just got to give it the once over quality control inspection ( fancy words for checking to see if I wired it up correctly :ROFLMAO: ) . . I got to get the red caps for the...

    Looking at buying a 2006 Bayliner Cierra 2455 that has seen better days at auction with an eye to restore it. Not sure what to look for.

    As stated, looks to be a 1988 and the engine/outdrive are obsolete as the company OMC went out of business 25 years ago. I would expect that the boat will need a new transom, engine mount stringers and perhaps the forward bulkhead. Bayliners of that era were real bottom of the barrel in terms...

    LiFePO Batteries ???

    More progress . . . I am back home, away from the boat for a day or so. . . . but I did make good progress on the wiring yesterday and this AM. . . It is fairly tedious, since I am doing both crimping and soldering and then heat shrink at the ends. I just got to remember where everything goes...

    Small and light boat for 5+ people?

    Perhaps the well-loaded aluminum boats that you see are actually over loaded. :unsure: Rigid Inflatable Boats (RIB) of about 12 feet in length have the capacity in the range that you are speaking of.

    LiFePO Batteries ???

    A bunch of my stuff arrived today, so I was able to get the components mounted to the PVC board. Some of the components are more straight than others . . . :ROFLMAO: . . Now just to wire it all up. :unsure:

    LiFePO Batteries ???

    Progress update . . . Waiting for parts/supplies to arrive. I did stop at West Marine yesterday for a couple of things, but the pricing is a bit scary vs. what I can do online. Anyway, I've got my battery box layout roughed out. The 2 engine batteries on the outside and the 2 house batteries...

    Fuel tank repair

    Many/most welding shops won't repair a used fuel tank, and for good reason as Matt mentioned. If the tank is 0.125" thick aluminum (check the certification label), then it is probably done. Even if it were 0.019" or more thick aluminum, I'm not sure I'd want to have it repaired . . . The area...

    LiFePO Batteries ???

    Yup, a dirty mess. More progress . . . slowly but surely. I prepped the lead that will go from the alternator isolator to the DC-DC charger. Keeping with the theme of the wiring, I added a label to the wire. . . Here is the wire installed . . . . . I'll be cutting/prepping the other end to...

    LiFePO Batteries ???

    One thing that I need to do is isolate the ProNautic 1230 from that accessory (now the house) battery bank, which will be the LFP4 batteries. In addition I have to re-route the third branch of the 2-Alternator/3 Battery isolator. Finding these leads have take a few hours. The charger lead was...

    LiFePO Batteries ???

    I'm not concerned about the charging current . . . the batteries will take more than the system can give it, and the recommended charging is in the spec. range of the other system components.

    LiFePO Batteries ???

    Executive Decision . . . :LOL: I was going to try to locate the LFP4 batteries more forward in the boat to get as much weight as possible out of the stern . . . BUT . . . The bulkheads and conduit passage ways are such that it is going to be a PITA to do so. After at least 2 minutes of...

    LiFePO Batteries ???

    The maximum continuous charge current is 100 amps. Which I recall checking as I looked into these batteries. So, in the extreme situation the Xantrex would charge at twice the recommended, but only 40% of the maximum continuous rating. They should be fine. I believe I can create a custom...

    LiFePO Batteries ???

    The Xantrex can/does put out 80 Amps for charging. But to your point I'll take a look at the batteries and the Xantrex to see about the limitation you mentioned.

    LiFePO Batteries ???

    Yes, I will be fine. :)

    LiFePO Batteries ???

    Progress Update . . . I got the battery shelf in the engine bay cleaned out of the battery boxes and took a look at the remaining wiring. Each wire (cable) is labeled as to its purpose/connection (Thank you Cruisers Yacht :D ). Also, much of my electrical 'stuff' arrived today, so I've...

    LiFePO Batteries ???

    Since it is raining and I'm bored . . . I'm seeing if I can bring any life back into a couple of these batteries. One battery was sitting at about 10volts and the others (6 of them) are sitting at around 5.4 volts. I've got a charger that does repair/(reconditioning) . . . essentially it...

    LiFePO Batteries ???

    In other news. . . I have found that the port engine still has a persistent coolant leak. Each year I try to fix it, but over the winter it looses about a gallon of coolant. Probably some cross-over assembly maintenance is in my future, as I believe that is where it is leaking.

    LiFePO Batteries ???

    and @airshot Yes, I believe the benefits of LiFePO4 have been discussed in this thread and elsewhere. I've ordered two 100Ah LiTime LiFEPO4 batteries with cold temperature charging protection to replace the five AGM batteries that served as the house battery bank. They should arrive...

    LiFePO Batteries ???

    Not yet . . . got to take the battery boxes out first. :LOL:

    LiFePO Batteries ???

    Despite the pouring rain, I was able to get the 7 (seven) batteries out of the boat. . . . . I believe one of the house batteries was internally shorted out, so I couldn't run the maintenance charge over the winter, as both the charger and inverter would peg at their maximum amps (80 amps...
