    How would you set the charging parameters for LiFePO4 DC-DC charger?

    Thanks again Mikefitz, I'll be getting the boat on the water tomorrow and will get to try the system for the first time in a real situation where I can run the diesel. I think I understood your idea by the way, but did you mean the "no absorbtion (boost)" floating voltage? My first...

    How would you set the charging parameters for LiFePO4 DC-DC charger?

    Thank you, Hi, it may be more than that, because my consumption is about 70-100A per day and the capacity is max 560A, but I don't want to charge to full. Except sometimes, if I know I need all A. I am sometimes at anchor for several days, I can also charge the batteries with a diesel...

    How would you set the charging parameters for LiFePO4 DC-DC charger?

    How would you set the charging parameters for LiFePO4 DC-DC charger? I use on the go being at sea at about 15-20A per hour, and I'm wondering what to set for boost, float and start charging values. My goal would be max SOC 85% when I drop anchor. SRNE 50A dc-dc/mppt standard values for Li...

    New system lasting less than an hour.

    This information can be found in the instructions for use of the Eco Worthy lifepo on page 6 , in addition they recommend doing a balancing every 2-3 months or so, breaking the chest connection and fully charging the batteries one at a time. If you didn't do this, your batteries can't give out...

    New system lasting less than an hour.

    Hi, when you first connected the batteries in parallel, did you charge both batteries to full and check that they were at the same V with a max difference of 0.1V when the batteries were sitting in for 1 day before connecting them in parallel. You said you didn't have a suitable charger, so I...

    Looking for a 12V 400ah LFP that won't break my wallet

    I just bought two 280A so I haven't had any experience, but I'm looking for information about Eco Worthy and tests in Germany, you tube, amazon etc. These seem to be mostly good in terms of quality, including of course disappointments (amazon) in tests 100A batteries have done well. It should...

    How would you connect the wires, Can you help?

    Thank you Mike for taking the trouble to analyze my situation. I am quite sure that the graph corresponds to reality (only solar control house battery). I'll take better sharp photos and information next time I go boating. Here are a few shots. I have a Blue sea electrical panel with fuse...

    Looking for a 12V 400ah LFP that won't break my wallet

    If you compare the values BSM A of these batteries, peak current A and time, maximum charge, etc. I think the Eco Worthy 280A offers a lot of value for money, if I need more A, buy two and plug in parallel Eco Worthy 280A, bsm 250A, peak current 850A/10s, standard charger 140A and max...
