Achim, many thanks for your reply. It seems to me that LFP cells are much easier to source in Europe than here, at least the brand and kind I want. I have decided to DIY with a system built from cells and a separate BMS.

Hi, I am in Europe. I have no specific LFP cells but the whole system is from Victron. That means I have solar panels from the brand Solara (Power M), the LiFePo from Victron, the MPPT regulators from Victron, etc. The system was designed and set up by preVent-germany.com (Mr. Stengel) a specialist in Solar systems. I am still amazed of how well it works and how much energy it generates. It is really plug and play without any worry about electricity ever again. I have not managed to get below 60 % with electrical heater, water maker, autopilot, fridge, etc.. Apart from sailing the LiFePo and solar system ist the best thing about the boat. :-)
Cheers,
Achim

Tri,
Where are you located in the world? I'm in the US and having trouble sourcing LFP cells. Also, could you share your plans as to your system and the battery brand you are going with? Thanks. Joe
