Gordon West recommends these batteries

The lesson from the Icarus story is not about human failing.
It is a lesson about the limitations of wax as an adhesive.
If you have an engineering problem solve it.

Re: Gordon West recommends these batteries

My biggest worry about those is that Lithium Ion batteries *can* explode with disastrous consequence.

The OP posted a link to Lithium Iron Phosphate batteries (LiFePO4) - quite a bit different than the Lithium Ion batteries.

Re: Gordon West recommends these batteries

LiFePo4 ARE a type of Lithium Ion battery. I have personally experienced LiFePo4 batteries going into meltdown mode. If it had been on my boat would have melted right through the fiberglass.

Re: Gordon West recommends these batteries

I understand LiFEPO batteries are substantially safer than LI Ion batteries found in many rechargeable devices. I think LiFEPO batteries could quickly overtake AGMs as mainstream. I’m going to consider them at my next battery replacement, which is now several years out. Any battery can be subject to explosion, if not charged or treated properly. At least some manufacturers are putting circuitry in the battery itself to cut them off from destructive chargers, etc.

There are serious advantages to these newer cells in weight, useable energy capacity per size, and most importantly in efficient charge profile.

Tell us the details and cause, ideally verifiable sources, insurance report or the like.

Have yet to hear one credible account, between lots of ignorant fear mongering and thousands of incident free installations.

Re: Gordon West recommends these batteries

I have 3.4v prismatic cells and didnt install a BMS.
I think people often over complicate using these batteries.
It seems much simpler..to me..than the other systems. There is no voodoo. I think some people market..solutions for percieved voodoo/unknowns

At the 6 month mark i recorded a difference of .001 volts on one 1 of the 8 cells. They are healthy and self balance....no need for BMS assistance.

Ive never bumped the upper and lower ends of capacity...maybe being too conservative...dunno.

People could easily promote and play up dangers of the other commonly used battery systems...but that would be old voodoo...

Re: Gordon West recommends these batteries

No LifePo4 batteries are yet certified for aircraft use, at least in the USA. That should tell you something.
Give your LifePo4 batteries a hard knock on the side and watch what happens.
Are they safe? Depends on how careful you are with your install. Having seen firsthand how they can meltdown, I will stick to other tech in my boat.
Just offering another perspective. I also the type who will not put propane on my boat.

Re: Gordon West recommends these batteries

I hope Mainesail chimes in on this thread. Some months back I found some LifePo4 batteries priced at a too good to be true level. According to him, they were. He's been using, testing and installing LifePo4 batteries in boats for some years now.
