Your analogies are some of the funniest things on YouTube. Wiped off e-bike battery beside a bag of outdated flares, almost lost my beer over that one.

Tim,<br>Hands down, this one belongs in the PS Top 10, Must-See, or Greatest Hits playlist. So immensely helpful, and timely. You are spot on about the manic panic and all too many sources of incomplete information. Way to go, PS!

Excellente synthèse as usual. Illustrée par quelques représentations hilarantes (as usual). Loved this "wiped off e-bike battery beside a bag of outdated flares"... Will E Coyote like.....

People worry about lithium on a boat, yet leave a phone on charge all night on their bedside table. Smart phone is lithium ion.<br>Lithium ion and lithium phosphate are completely different things.<br>Your Propane is more dangerous then lithium lifep04.

Really well done video, Tim. The idea of Seamanship and risk assessment is spot on!

The behavior of the LiFePO4 cells in the event of a malfunction is often overlooked. The pressure relief valve opens, releasing hot gases that contain many explosive (high hydrogen content) and toxic substances. These gases need a safe way to escape. And just to be clear: This can happen even without any user error, for example, due to a manufacturing defect in the cell.<br><br>In many DIY boat installations, these batteries are stored directly under beds or in tight wooden boxes. There is no proper ventilation and no heat-resistant path for the gases to escape. Additionally, the ventilation system should prevent moisture from entering the battery compartment.<br><br>Although many retrofit installations ignore these considerations, surprisingly few incidents occur with LiFePO4 batteries on boats, which speaks to the safety of this technology. And the article is absolutely right: Security is not just one component. It is a concept that covers the entire system.

I honestly can't decide whether I watch your videos because of how informative they are or for the dry analogies you throw in 😂

Great advice for sailors! Thanks for what you do! <3

Very, very good video Tim. You hit the major issue on the head, installing LiFePo4 is a system upgrade not just a battery replacement. So called "drop-in LiFePo4 batteries" simply don't exist. If you don't know what you are doing there are a few good sources of information on the Internet, but vet your sources carefully. Keep the good stuff coming.
