Question Replacing house batteries

[newmarokie]

Neal,
What kind of aircraft do you have? With all the "yellow tag" stuff and approvals, was the LiFePo battery replacement a logbook concern?

Experimental so I can do anything I want. Carbon Cub FX-3. But the EarthX batteries are certified as well.

People need to stop associating LiFePO4 with solar, there is NO connection. My airplane has LiFePO4 because it's a better battery, lasts at least twice as long, therefore more cost effective, charges much faster, on and on.


There is more labor involved in the first switch to LiFePO4 as you have to seal the battery bay and you have to be temperature aware.

You not only save weight but once your battery bay is "renovated" you now gain a ton of storage too.

I am aware there is no connection with solar, but most that I have seen go Lithium with solar panels for off grid camping. I just want to loose some weight on the drivers side of the coach and have power without having to worry about going below 60% SOC. I think I'm sold on LiFePO4, but just what is involved with sealing the battery bay? How have those who have lithium done this? I'm sure I could figure it out, but best to learn from those who have.

Here was my conversion….

Move to Lithium

So as I get ready for my Lithium project, I began to think about the best way to wire them. I will have 8 100ah GC2 sized battleborns. I know many of you use the wiring method on the left (see below). I have seen articles that say the diagram on the right pulls power from the batteries...

Go to the last page for the steps on enclosing it.
Hope it helps

Thx Rich, I'll check it out

I’m not sure if you really half to seal it unless you’re going to use the Rv in extreme temps or the battery compartment is vulnerable to debris. I did do mine with thin metal sheets I could bend by hand and self tapping sheet metal screws.

Good point, I'm not sure where the "seal the bay" comes from, I don't think it's required other than for temps. But you can take the opportunity to make it a great bay for storage, etc. as I gained a lot of storage space in mine. You could get creative and build a battery box, etc. I believe and that would work which is what ended up happening with mine simply to enclose them as they don't need to be vented like AGM/FLA require.

Agree. In my prior rig I installed BattleBorn as drop in replacements and didn't seal where they were located. I didn't intend on using the rig in extreme weather and the internal bms built into each of the batteries would have protected them anyways if I had tried. If they come with an internal bms and/or heater built in (or you install a battery heating pad) I also don't see a "requirement" or need to seal the bay. Even an external bms should have a temp sensor to protect trying to charge them in extreme cold.

This is a really tempting battery. 2 of these would replace the 8 I have now due under 2k
