Changing from BBMS to DC to DC charger

[Stoïque]

When I bought my boat, it had a sealed lead acid starter battery and 4, wet cell 6 volt golf cart batteries wired in parallel for the house bank.

I decided to add four 100ah LiPo4 batteries and use a battery bank manager system (BBMS) invented by Clark Willix of Clark’s Adventure YouTube channel.

I wish I had found this forum before I did all that work and spent $$$, as I have had nothing but problems. So, I have decided to take the entire BBMS system out and go with a DC-to-DC charger.

Is there a comprehensive tutorial or any other resource I can use on how to integrate a DC-to-DC charger into my system?

There are a number of people who claim that using a solar MPPT Controller works better than a DC->DC Charger.

I have no direct experience with either, but it's something I'm going to researching.

Your comments about the BBMS will be interesting to many.

I recently went through an SLA to LiFePO4 conversion on my boat, replacing the house battery bank with lithium. Here is a link to my thread . . .https://diysolarforum.com/threads/design-of-agm-lifepo4-solar-system-for-my-boat.78139/

I also considered the BBMS for a short time, but opted for the approach of a DC-DC charger, along with a solar controller.
