LiFePO4 drop in's are they really a drop in?

Interesting. If I try these it’ll be a Trojan.

Considerin the initial cost of the batteries versus a conventional flooded cell or AGM, I'll stick with them. I can buy a boatload of conventioanl batteries for what one costs.

Not sure what that comment has to do with the article.
I personally am very happy with LIFePO4’s, especially their ability to hold voltage at high draw, which I is something I could not achieve with wet cells.

To OP, thanks for the article, interesting read!

Hi Little Bill,

Thanks for posting that!

He is pretty informative, no screwing when on the water cobbing an electrical system.

If you really delve in LifePo4 do a search on the forum there, it's more towards prismatic cell battery builds than dropins though.

I agree with mainsail. Drop-ins are not ready yet. Got to get rid of lead-acid mentality.

Another one to check out, not as technical but worth the time reading

We have a 200amp 4 cell prismatic battery in the RV with only cell based voltage metering. It's been in there and fully operational for the past 4 years purchased it after first reading the MainSail mentioned article. One of the best if not the best improvements to the RV over the years.

Picked up two of the 100amp "drop-in" batteries (mentioned in my link) 3 months ago from Drew for the fishing boat. They are also prismatic cells plus internal BMS and Bluetooth. They are preforming GREAT.

As a reference, the place I bought my LIFePO4's from (drop ins) sold them to me for $725 Canadian per 100AH unit (I initially bought 4 and just bought 1 more). If you want the link, PM me.

Battleborn batteries are a little pricey but they do have a very good technical section with specific settings for my Magnum charger/inverter and a good warrentee. I have been thinking about putting some of those in my coach but just haven't come up with the money yet.

This is a question and not a comment...

Doesn't a manufacturer specify exact use and maintenance instructions for their product?

How far off-spec or how different are the prospective vehicle's charging system voltages from the battery manufacturer's voltage specifications?

My lifeline's terminals are not compatible with the original factory battery cables. Lugs would have to be installed.

Merely some nit-picking notes... :)
