That’s what I’m doing. and I’m going to swap a couple of the loads around in the panel.

Looking for a few ideas on how I should wire my inverter into my boats electrical system. The boat is powered from two 120V 30 A shore connectors that’s typically Line 1 and Line 2. Away from the dock, it’s powered by a 7.3kw 120V generator, and the transfer switches join L1 and L2 together in...

They group them together because there is still the possibility (however slight it may be) of thermal runaway with LFP4, and the way you protect against it is similar Enough to other lithium batteries.

They are grouped together.

Installing a couple of lifepo4 batteries inside the main cabin, where I sleep. Are there any special ventilation requirements that I need to consider?

Its too bad these requirements can’t be shared with those of us not in the boat building or repair industry.

Do you have a link to the case?

I’ll take both if you still have them

Underwriters Labs gives you free access to their safety standards,

It’s ironic considering the second sentence in this letter from the ABYC president. https://diysolarforum.com/threads/letter-from-abyc-president-re-lifepo4-safety-on-boats.48022/

I tried searching “ABYC A-31 PDF” And it looks like I have to be a certified technician to get access to the standard.

Is there a way to access ABYC standards as a DIYer?

Where do you see the mounting information? The manual that I’m looking at only Mentions mounting to a wall, and doesn’t discuss floor mounting. It also says to put the battery in a separate compartment? Can I not put both of these in the same location? I was trying to fit them both under the...

Could you give me some feedback on this setup. I currently have a boat with shore power and a generator. Shore power comes in as split phase with 30A on each phase. Each phase is switched individually. So, when I unplug or turn off the shore phase, one phase will drop out before the other...

I’m looking at using one of these to power the AC in my boat, but I don’t have a lot of space to mount this and the necessary batteries. ive looked over the installation manual and I don’t see anything about mounting orientation, so I’m curious if they can be mounted horizontally instead of...

is there a reason why the lead acid banks are generally higher capacity than the lifepo4 banks? Could you safely do 600Ah of lifepo4 with 200Ah of lead acid?

I would likely build my own batteries, but I agree with you that a 12V system would be simple and easier to implement. But also, I wouldn't charge these batteries directly from my alternator(s). I would use a 12V - ##V converter just to limit the charge current. So I could charge 12 or 24...

First goal would be to be able to power the AC (120V, 14A) for a day trip. Maybe 4-6 hours on the boat, and a 70% duty cycle. Secondary goal would be able to run the AC overnight. Maybe able to heat water and take a shower, although I would be okay if that required turning off the AC while...

If you were going to build a pack to power an inverter to supplement your generator, which voltage would you pick and why? current voltages on the boat are 120v and 12v. The boat is not currently set up with a house bank.

Seems like a great idea to solicit a person to build batteries so that you can pass the litigation off to someone else when a pack takes out a $4M yacht.

I am tempted to stay at 12v, since that could then be used for the rest of my 12v systems, and it would be easier to charge the inverter batteries with the engines. I also already have one 12v, 280ah pack built. It has been built for about three months, but hasn’t been used. I suppose I could...

I‘m working through an example of adding an inverter to my boat to run the ac overnight. Currently. I’m using a generator,but would like to avoid the constant hum of the Genset running overnight. Most nights the ac runs about 50% of the time and pulls about 11A . I would like to power this...

Coming back to this, I‘m leaning towards building a L.A. / LFP hybrid system using the Cyrix combiner from Victron. I can use this in combination with a Victron VE.Bus BMS to disconnect the the LFP battery out of the existing system. Then I would just need a way to disconnect my 25A charger...

What about using a battery combiner that’s intended to mix lead and lithium: https://www.solar-electric.com/victron-energy-cyrix-li-ct-12-24v-230a.html

Just curious, if you connected The LFP batteries to the L.A. batteries with a high current diode between them, to stop the LA from back feeding into the LFP, what negatives would that introduce?

Can you share how many people you think have tried this in their boats?

I want to setup a solar charging station for my golf cart. It runs off of 51.2v, 90Ah Lifepo4 batteries. I have purchased four 100W panels and a victron mppt 100/15 charger. At first I was thinking I would mount the panels to the roof of the golf cart, but we drive the thing on the road and I...

do you mind sharing what vessel you are mounting the solar panels on? I want to mount some panels on my Sundancer, but finding a spot to mount them where they don’t get in the way of the fun is challenging.

I’m asking because I’m considering it. Have you posted any details on your setup?

With that large of a pack why not run the windlass on it?

You tie the LFP bank directly to the FLA In parallel

How many of us actually do that? In my use case, I might do this 300 times over a 10 year period. ”might” being the key word. In my case, I am more interested in keeping them from shifting and putting pressure on the terminals than I Am cycling these batteries out of life.

what constitutes a “cycle”? If a battery is partially depleted to 60%, recharged back to 80%, is that a cycle? What about down to 75% and recharged back to 80%”

Where’s the manual for the Eve cells?

Holy crap. You just opened up my BMS options tremendously. I already have a solenoid with a switch in the dash. I can rewire that to go through the BMS easy enough.
