The List

LiFePO4 battery bank

The [current] List for our refit has kicked off with a huge Defender order! Special thanks to our friend Judi who helped us in getting the best deals during their annual sale with a volume discount.

The Dolphin 460 is a 2005 built boat with most of her equipment original. When we made the purchase, we knew that most things would need replacing after 13 years, so we saw it as a clean-slate to outfit the boat with exactly what gear we preferred.

We have experience with refits over the years… some forced by nature, and others due to hitting that cycle of preventative replacements needed every 10 years or so. Salt water and sun are extremely destructive, so regular refits are part of a life’s plan for boat living.

Our first few projects were kicked off after moving out and optimizing the Manta for new buyers. We took the LiFePO4 batteries over to the Dolphin and added another set of cells (4 x 3.2V cells). The custom way we use LiFePO4 batteries without an automatic battery management/balancing system is not something we wanted to pass on to someone cold.

First, the 4 new cells were top balanced in parallel to 3.65V. Next, the old cells were top-balanced again. Finally, all 12, 3.2V cells top balanced together and then combined in a 3P4S configuration to make one, large 12.6V battery (540 Ah nominal).

A huge bonus was removing six Trojan L16H's from the Dolphin at 125lbs each. These were quite a challenge to remove from the settee with the two of us; the weight and size difference of cells is significant. It was great to lose 750lbs and gain some space back (…more gin).

A few projects that have been knocked off over the last month include:

  • Install Morningstar MMPT solar controller

  • Replace (3) temperature controllers for AC/Heater

  • Install carbon filter in-line for fresh water

  • Replace outdoor speakers, add Amp and rewire entire Fusion stereo system (cussing involved!)

  • Replace courtesy lights

  • Install brushes and seals to slider door and window to keep the bugs out!

  • Re-plumb, rewire and install port toilet

  • Install Oceanair shades (2) saloon

  • Flip and rethread trampolines

  • Rewire shore power cable

  • Remove sump pump and install Whale shower pump

  • Install drawer sliders in galley
