Is the future Lithium-ion batteries 4 Boats instead of conventional batteries?

[ralexa6808]

The article doesn't talk about marine batteries but I would think it's something that is not very far off into the future.

Quote from the article that prompted this posting:
"A typical lithium-ion battery can store 150 watt-hours of electricity in 1 kilogram of battery, representing more than double the capacity of nickel batteries."

The 8D's I have are pretty heavy, and if I could shed a bunch of weight and still have the power / storage needed, looks like a win/win.

Anyone have any knowledge or thoughts about these batteries?

Update / edit: Did a search and found this article....guess they are already here...but the cost is crazy compared to AGM's, still you won't need to change them out....ever.

7 times more expensive. Maybe in the future when the supply and demand forces the cost to go down will it be worth the change.

They also require special care with charging, monitoring, etc...

We have a Sea Bob underwater scooter sitting here on the boat that the previous owner left uncharged for a few months. Battery pack is dead and can't be revived. Cost to replace the battery is over $5000.

I don't see the benefits of that technology for boats. Cars, toys like that scooter, or any application where you have no space or weight capacity for traditional batteries yes... but not on a 50 or 100k lbs boat

LiFePo is being used in boats and solar all over the world.

Yes it cost more BUT when used in a high cycle environment pays for itself easily.

1) cycle life of up to 5000 charge / discharge cycles compared to a few hundred for flooded lead acid and agm.

2) charge efficiency at over 90 % better then flooded lead acid or agm. Less time and power needed to charge them. Low loss during charging.

3) can be left partially charged and will not damage batteries.

4) discharge 80% not 50% per cycle so more power per amp hour.

5) lighter weight than lead technologies.


The ones i sell and install have built in electronics and charge controllers at a level of individual cells. They also have a network connection to allow me to check and confirm battery health.

Rarely will one go completely dead. It happens but not often at all. I've not had one go bad in the 5 years I've worked with them.

Cells don't just go bad or boil out.

By the way $5,000 buys a lot of batteries. Enough for an inverter bank.

There is a fairly commonly known hack for bringing "dead" LiPo cells back to life. Connect the pack to a 12v dumb charger for a few minutes, the object is to bring the voltage above the "death" threshold so they can be charged by the regular charger.
NOte: there is a risk of fire, so try this OUTSIDE away from anything you want to keep and stand way back!

Know the battery chemistry before playing games.


Lithium is only one part of it. There's a bunch of different chemistry and each has its properties.

LiFePo will not burn.


Here's a link that may help keep people on track here.

When LiPO came out on for Remote control toys, it changed the game. Electric helicopters and drones!

Lots of energy stored in these batteries when fully charged. Think of them like a tank full of gasoline...because that's what they will do if shorted or damaged.

I wonder how the installers will handle the heat. I have lithium batteries in my BMW i3 (all electric) and they have a separate cooling/heating system just for the batteries.
