lithium battries - suitable ones for a AS

I see people discussing lithium batteries can some please post links to ones that can be used as either 6v or 12v replacements. as well, can they be charged with the PD 4655v or Parallax 8355 that people have been recommending any other help would be appreciated

You can search for threads on this, there have been some recent ones so even if you just go to Electric and scroll down you should find them. Bottom line is there is no inexpensive way to do this. Your charger is not right for Lithium batteries, although PD is talking about a lithium capable replacement maybe this year. The "replacement" lithium batteries are an expensive compromise. If you want to go lithium, you need to pay to do it right or you are throwing money away. Guys like Lewster are doing proper lithium installs, PM him with specific questions. If you do not want to spend the money to get the most out of a lithium upgrade, just buy AGM's and move on.

You might look at these offering, they have the same look as a lead acid battery. I don't know about the manufactures, but the links will take you to a couple of 12DC 100Ah lithium ion battery. Note the $1,000 price tag.

ISBrodsky says it exactly right. This will be an expensive but worthwhile upgrade if you're trying to save weight and space. But MUCH more expensive than your current setup and going to AGM's.

Lewster is the guy to talk to if you want to upgrade, and he does great work.

You are close to us. In Malibu with sport 16. Where do you go for work on your AS? Where would you do Lithium?

Hi

Battle Born will happily sell you "drop in" lithium batteries that will run in place of your existing lead acid batteries. They are roughly group 27 size so check your battery box to be sure.

That said, you are spending about $2,000 on a pair of them. That's not exactly cheap. They will give you >=2X the usable amp hours of what you have now so that makes it *slightly* easier to justify.

Converter wise, you can get a "lithium specific" converter from any of several outfits. They are in the "about $200" range. Simply put ... not much compared to the rest of the money you are putting out. You can use the converter you have, things will go a bit better with a lithium specific unit. Past that, there nothing you *have* to change out / need to change out.

The 8355 or 4655V converters are not compatible with Lithium however the new 4655VL is. It has a jumper for lithium setting. It fits the Parallax 7355 or 8355.

Hi

I agree 100% with your statement in terms of the older converters not being *ideal* for lithiums ( = I would not use one ). However the fine folks at Battle Born seem to be recommending very similar converters.

I'm still not quite sure why you would *not* go for a new(er) converter if you are spending a pile of money on the batteries. They certainly work better with a proper converter. Switching one out is a pretty trivial task.

Now, yes, you can go a bit insane on various "upgrades" when doing lithiums. A lot of us do indeed do that. It can get very confusing because we toss in all the other this and that in our projects. The bottom line is still that you can do it with very modest changes.

we replace the As battery with the battle Born Lion

https://battlebornbatteries.com/shop...cycle-battery/

we also replaced the converter with a victron converter/inverter 3k model

If you are not ready to go to an inverter/charger, Progressive Dynamics also has a 9100L series converter made specifically for lithium batteries. Output is a constant 14.6 VDC.

I have the progressive dynamics lithium converter coupled with 2 battle born batteries. It works very very well. Lithium is an amazing upgrade. Apart from the converter. I have 720 watts on the roof and my batteries are charged by lunch time on a sunny day. I like the idea of keeping the converter and the inverter separate. Then if one day, one decides to fail, I can still charge my batteries.

For LiFePO4 batteries, the PD 9100L series and the Boondockers ending in CL do work with older Airstreams having a deck mount type converter. Parallax 7355 for example and the old Univots that were deck mounted including Litton, Newmark, Triad-Utrad.

My 2018 International Serenity has a deck mounted converter, the WFCO 9855. The PD 9100L should work just fine when I upgrade to lithiums later this year.

Hi

If you *are* going with a combo of a fixed voltage converter / charger *and* a solar charger .... Set shore power converter / charger to 13.6V rather than 14.something volts. Let the solar do the absorption part of the rock and roll. There's not a lot of energy going into a lithium system in the 13.6 to 14.6V range. Getting there with solar should work just fine.

Indeed having two devices force the batteries into absorption is probably not what you really want to do. They simply don't need it very often. Letting one device or the other handle the task should get it done plenty often enough.

There are a lot of details about the "why" in other threads here. That includes direct input from Battle Born. It's probably better that people dig into that if they want more information. Re-quoting everything here will inevitably leave something out.

One of the nice things about at least some of these converters is that you can set the voltage with a screwdriver (or an app, or a computer program). There's nothing magic about 14.6. They are just as happy putting out a constant 13.6 or 13.2 ....

Bob. Do you know the location of the information you're talking about. I had a search through some battle born posts,, but could not find it.

This is the info battle born provides in their setup guide
Bulk/Absorption
For your Bulk/Absorption stage, the ideal voltage is between 14.2v-14.6v. This range will allow
the battery to fully charge any higher then this and the built in BMS will send the battery into a
protect mode.

Hi
The info is deep in one of the "here's my solar build" threads. Simple answer is hat lithiums work different than lead acid's. When you go up above 14V you are running the cell balancing part of the algorithm. You don't need to do that very often ( once a month maybe). The rest of the time, anything above 13.4 keeps the batteries fully charged. Below that point (like 13.2) you get into the discharge cycle in a fairly big way. At 13.2, my Battle Born's were down around 70% capacity.
