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

I figured this might be interesting to those interested in drop-in replacement LIFEPO4 or the standalone cells themselves., based on the article below does not appear that is truly the case.

Its a long read and aimed toward boats, but he has a ton of experience and data to back up. if your interested in LiFePO4, i think its definitely worth the read.

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