Lithium ion batteries

[Bribass]

Hello everyone
I am thinking about investing in some lithium ion batteries for my boat. I was hoping to gain some information and knowledge about them before I go spending the money. What are your thoughts? Are different brands better than others? How many volts and amps do I want? Also can I use a lithium battery for my old mercury outboard? I am also just looking for general knowledge, thoughts, and reviews. Any ideas and knowledge helps. Thanks!

Personally, I wouldn't do it. You would have to buy a dual purpose LiFePO4 and then you have to get a DC to DC converter to properly charge it otherwise you will burn out the alternator.

If you are talking about getting some lithium batteries for a trolling motor set up, that's another story...you still have to get a proper way to charge them.

BTW...I love lithium batteries. I use them for my travel trailer. I actually made my own.

Don’t they have a longer lifespan and also charge lasts longer? For my trolling motor could I just put it on a trickle charger? I don’t believe it’s hooked up to charge off a alternator.

LifePo4 batteries are designed for long steady draws, such as a trolling motor, or running lights, radio, accessories of every type. The hard quick draw of a starter is not ideal for the overall health of these batteries so it is not recomended. Powering inverters in travel trailers is an excellent use for these batteries. They do REQUIRE a specific type of charger designed for Lipo batteries, using a regular LA type charge could cause an explosion or fire. My particular LifePo4 battery runs my trolling motor about two/ three times longer than my old group 31 dual batteries and the Lipo does charge more quickly. Do your research before purchase, they are great batteries and only pennies more costly than lead acid deep cycle batteries, but you need to buy that special charger. If they suit your needs, you will love them!
