    Bad Lifepo cell or BMS bad

    I do have another dilemma, I now have 2 sets of 12v at 280ah, using the 120 Overkill Solar. I did the top balancing and all was okay. This operated about 2 weeks. I had not disconnected my charging alternator, and started that engine but only for about 20 sec., it's a small 65amp alt. . Since...

    Hey to all, I am new here and looking for help! I live on a boat for the past17 yrs., in that, I've gone through a few batteries (lead-acid).

    yes my friend, this is a custom cat. The problem I always have is the haul out, for the wells are normaly to fit a boat that is 24' beam max.to be a wide well for haulout. I normally go to St. Kitts there well is 33' wide. There are a few places, but need to find them. In the States is a bit...

    I agree, if you have it ...use it Well that's why I'm here, to learn what I don't know. All you people have beem kind to someone who knows very little of this type. So when you say to match the charger, which mine is 60amp at 120volt. And my solar I have 2 Morning star MPPT 45, that are always...

    Ok, so the most draw at one time is how you size the BMS, in my case that should be less than 100amp max..Any other high draw I would use my gen set. Correct?

    Hello, thanks for your input. The inverter is a Cobra 2500w 12v. Most of the boat is set up for 12v operation, that includes boath refer. systems. (14cuft refer., and 5 cuft freezer) combined they draw 12.3amp. @ 45 to 50% cycle so in a 24 hr time = 147ah. thats my largest load! Smaller loads...

    Thanks for the return, so when sizing the BMS, the battery amp hr is not as important (100ah to 400h) for the BMS i've seen are mostly mark for 100ah. Because I've looked for a system that will match the 280 - 300ah. Or may-be I'm missing what your saying. I understand the schematic, it's...

    Hello, is ture, the mimi's are more eff., but you still need much power. I think you would need to do some checking for 220v and depending on the size (BTU) check the total amp draw and size your solar and batteries as such. Don't forget, the start up amps are greater than run amp. these systems...

    Hey to all, I am new here and looking for help! I live on a boat for the past17 yrs., in that, I've gone through a few batteries (lead-acid).

    Ok, so it's close to time in replacing my battery bank on the boat. I'm now looking at the lithium type. My system is 12 volt and having 660amp house. The boat is wired at 12 v and not willing to change. So, I'd like to get 8 200a cells or may-be go with 150a cells. for a total about 400 to...
