Re: What to do with LiFePO4 batteries when the boat is layed up?

Be sure to check with your insurance company before changing your battery technology. You may find yourself with a voided policy if you file a claim. Some insurance companies now have very strict policies regarding lithium upgrades.

LifePO4 are a new technology for cars … it was too expensive . I am changing my battery bank for 4x200 A / 24v Mastervolt LifePO4 batteries.

I’m reading an article in the Wall Street Journal this morning about Lithium Iron Phosphate batteries become the prevailing battery technology for electric cars in China.  The article includes the following quote of Elon Musk: “I’d personally slightly opt for the iron pack, as it wants to be charged to 100% whereas nickel prefers ~90%.”  So is there really no concern about charging LiFePO4 batteries to 100% or is Elon talking about a different technology?
