What Dr. Bob said - lithium ion (Li) batteries are the ones involved in the fires, not lithium iron phosphate (LiFePO4). It is incorrect to generalize that all "lithium" batteries are dangerous and would risk denial of insurance coverage. LITHIUM IRON PHOSPHATE VS. LITHIUM-ION: DIFFERENCES AND...

What is the brand and model of your AC to DC 14.5 charger? The screen seems like a good feature but if I EVER get my LiFePO4 activated (which is by the initial charge, which at the moment I seem unable to do), that same data will show up on my Renogy phone app via bluetooth from the battery itself.

Anyway, back to the Renogy DC-DC charger and LiFePO4 battery. The DC-DC charger is the 40 amp version. I hooked it all up to bench test. I am confident all the connections are correct (i.e., the positive and negative are clearly marked for the input to and output from the charger, and I triple...

That charger being a stand alone "shore power" charger would only be used in my driveway or garage plugged into an extension cord. In the salty marine environment, the charging will come from the alternator to starting battery then to the lithium battery through the DC-DC charger and from the...

This (20 amp AC to DC charger for lithium batteries) looks like a good solution to shore power charging of LiFePO4 batteries, seems better to me that a work-around with the battery to battery (DC-DC) charger and the problem of the D+ ignition connection requirement for the Renogy DC-DC charger...

When we go to Eagle Harbor, we just anchor, why use a mooring ball when you can anchor? It is also difficult to land there except at full high tide - way too mucky otherwise.

Here is my revised block diagram which I THINK is the way Bob explained it. Bob and Boris, do you agree? Two things are missing: the locations and amperages of fuses, and (what was puzzling me reading the manual of the DC-DC charger but dawned on me reading Boris's post about the "motor...

Block Diqgrqm of Lithium Battery Charging System Revised

Excellent! That is what sold us. We tried one at a CBGT. We can step over the gunwale to get in or out standing up. We have 5,328 miles experience on the Great Loop, and we speak from experience! Also Baxter-approved! Corretion - 5,428 miles!

The best dinghy we ever had was the Alaska Series by Gary King. Very tough material, inflatable floor, and the Bearclaw bottom could be dragged over rocks, barnacles, or whatever. We had a 2 hp Merc, and it also rowed extremely well. But it weighed 50 some pounds and got too heavy for me to...

+1 on AquaMap not only for Florida but for ANYWHERE. We navigated the entire Great Loop, 5,428 miles, with an iPad on a RAM mount hanging down from my radio rack attached to the bottom of the chart shelf. We started with Garmin Blue Chart, now discontinued, and we ended up AquaMap, which is...

Thanks, Boris - all great sources! No need to mark up my original diagram, I will be doing an entirely new one, and look forward to your and Bob's comments. What would the symbol for a BMS be?

If I have correctly understood Bob's post, ALL the normal charging sources (alternator, solar, and on-board Guest or other shore power charger) go directly to the FLA starting battery. The VSR is now out of the picture. The FLA starting battery is kind of a buffer for all charging sources. The...

Fascinating, love these pics! Patty and I have stayed at the Skamania Lodge in Stevenson, a very nice place. I confess I had never heard of Beacon Rock, so I Google it! The odds of my hiking up it are less than slim to none! As are the odds of our cruising the Columbia! Beacon Rock Wikipedia entry

And I should add that the total cost of the battery and DC to DC charger directly from Renogy was $683, or about the same amount as two AGM batteries - I know this because I just put two AGM batteries in my truck camper before I got tuned in to lithium batteries. Honey found a $36 coupon that...

Renogy 12V 100Ah Lithium Iron Phosphate Battery w/ Bluetooth and 12V 40A DC to DC On-Board Battery Charger ordered and confirmed! On to LFS for required buss bars, breakers, and fuses!

Thanks! Let me take the last question first! The windlass is powered from the starting battery, and we only use it when the engine is running. It was factory wired, as it was part of the 2005 factory Seattle Boat Show package. It has worked for the 17 years we have owned the boat. Not sure where...

Thanks, Boris, I certainly don't want to fry anything! That is why I posted my questions here first! Here is the battery I am looking at - it has a BMS and bluetooth - and it just went up by $20 overnight. Same questions for you as for Bob. How does my diagram change, i.e. what gets connected...

Thanks, Bob. How would what you are saying change my block diagram? Can both the alternator and the Guest both go into input of the DC to DC charge (my main question)? Sounds like changing out the Guest would be a good idea, but to start I probably will just just keep the Guest. I think I don't...
