Everything is a super-cell

I can smell the smell .... 😊

Balancing with 2 amps 800ah cells will take a while

Recomend you rewire and go for48v

Sounds like too much heat to have the fuel in the stove with the fire. Successful versions I have seen slowly drip fuel into a burn chamber from a small tube that goes to the fuel container outside of the stove.

Just to say, the preset voltages are more made for lead acid if uses lithium it is primarily designed to be controlled by a BMS output some of your logs appear to be a little big I would recommend changing them out of the proper size for the boat used only because it could create an issue if it becomes loose

Thank you for sharing your knowledge.

Hey Thomas, glad I have come across your videos. Just acquired a historic 1912 46ft Raised Deck Motor Launch Yacht. And I need to do some of this on the teak also. So helpful and look forward to see how it's coming. Sure thankful for our S. Ca weather...Cheers Capt Ron on Yacht Vessel Edna...

Hello! I’ve been removing all the teak edging to waterproof the boat as you did. What did you do at the corners? They seem pretty beefy, Are they structural? Any tips?

Great video, strangely exciting from beginning to end. The sound of the tanks popping had me jumping in my seat 😂

Your monitor looks very similar to my BatGo monitor I have but my voltages are way off. I use my DC volt meter to see where im at. I only use my BatGo monitor to balance my LIFPO4 cells, and it does a fairly good job at that. BTW Ive gven up on indvidual cells and decided to go with LIFPO4 batteries with their own BMS/ Balancer in them.

A lifepo4 when stored, is stored at something like 40% SOC, since your is not stored but in use chare at 70%, should a good spot. Remove the crappy voltage monitOr, add a bms...😄

Lifepo4 do not release gaz, if they do they got an abnormal internal pressure caused by overharge, voltage...amp....the valve is a security valve, a cell leaking is not reliable. A 4s like your should be charged at something like 4x3.45v. Inspect each valve (the blue oval thing) if they have not budge. If not inspect, of any leak. Add a bms....!

I dont think you should have any off gassing with lithium i wonder if a cell has over charged causing it to off gas or it's the charger making the smell... glad the battery bank tested out well we are at 3.5 years on our diy bank and it's been great.

those bg-8s need calibration, they aren't the most accurate out of the box

Each 3.2v cell should be connected to a BMS balancing lead. If I understand, you have connected 5 cells in parallel with a single balancing lead for the group. If so, variability in the 5 cells may not be managed reliably. A more conventional approach is to group 4 cells together and use a BMS for that group. You would then have 5 parallel groups of 4 for 12.8 V nominal. I could misunderstand or I could be wrong or both. If your system has worked without problems for a long time and you manually check from time to time, you should stick with it. However, I am concerned with the charging smell. The should not happen in normal charge - discharge operations.

We have the exact same batteries wired exactly the same as yours... th-cam.com/video/2uYENzaDBY4/w-d-xo.html We've had no problems ballancing with the SBMS0

Assuming from the dark image that's an ISDt Battery Go, those are easy to calibrate. Just go into system information. When there hold the middle button down until it beeps and do that two more times and you should get the calibration unlock screen, just copy the code as you see it to unlock.. Should easily be able to get it within 2mv.

Sounds like lithium clusters

I wouldn't recommend hooking up your battery that way. You are hiding problems with the cells. It should be arranged as 5 batteries of 4 cells in parallel. You should have a cell monitor on each of the 5 batteries. I'm guessing you do have cells that are out of whack. LiFePO4 batteries don't share power very quickly especially when charging. Old cells will get out of balance. Your BMS should have a balancer but I'd recommend for old cells an active balancer. With 5 cells in series no balancer is going to be able to help. There is just too much capacity for either the BMS passive balancer or an active balancer to do any meaningful balance. I have a 24v system with 960Ah of capacity. It is divided into 4 separate batteries. Each has a BMS and an active balancer. Unfortunately they aren't the greatest cells but the active balancer keeps them in sync.

Nice job, thanks

Still leak free a year later? Just bought a Formosa 41 and need to do this!

good idea :)

Great job thanks. i wonder would a "multifunctional garden cleaning shovel blade" be a more sturdy scraper. Cheers

Next weekend, I'll be starting a 4.108 for my first time. Have had the boat for 2 months preparing. Wish me luck. Any tips? (Fresh oil, fresh ful, good battery, new alternator, new starter, strainer working, impeller on site for after compression tests.)

The problem to use the drive or not is the intake in shallow water like sand in the intake!

You are doing great my man!

Fowling along sweet working good...

The stuffing box story reminds me of the guy who went through a bag of carrots when he knocked off a sea-cock while offshore.

You don’t need to put it in gear, you can certainly run it in neutral to flush it out. You probably do more damage by putting a load on a cold engine than flushing it in idle. Just my opinion!

Try a defrost cycle

be careful lol

I love the classic design of the Formosas. If you ever want to sell your boat ... In about 3 years I'm looking for a boat of this size for my retirement. 😁 Greetings from Germany

I doubt it is a transformer, sounds like a couple of capacitors that dried out !

I have a 4-108. The oil pump is on a hose that I can pull out into the cabin while pumping into a container. Also find yourself a silicone container used in cooking to place under the oil filter to catch the oil that escapes when removing the filter. It’s recommended to pre fill the filter before placing it on the bracket, but it’s not really necessary. When you start the engine after the change, advance the throttle about half way. Start the engine and it only takes the a second or two for the oil pressure gauge to respond. Also you should put a quart of Lucas oil in with every change. According to the manual the engine takes 4.7 quarts after an oil change, so adding 4 quarts of oil and a quart of Lucas oil fills it slightly more. But doesn’t hurt the engine.

Great story and advice ~ thanks for sharing !

You could try the drip design and have a line up top go down into it. Google "High Output Waste Oil Burner DIY".

Have you researched waste oil drip stoves? I use one in my pigpen and it runs for 8 hours on 4-5 gallons. Something that small could run for quite a while on a gallon. Most liquid fuels should work

Maybe a 4 or 5 inch Silicone cake pan would work better. They are pliable, so can be folded to fit in the port hole, and can tolerate high temperatures. Checked on line: "Silicone 5 Inch Cake Pan Round, Set of 4" for $12. "Silicone 4 Inch Cake Pan Round, Set of 4" for $10.

Fire insurance coverage has left the building (boat).lol

Curious if you'd tried burning coal with the wood?

What about the 6 hour alcohol cans? Denatured alcohol. Just need some ventilation.

Foils gonna burn.lol

Great information. Please redo the video. Please edit out 3/4 of the run time. Add lighting, please. Please don't block our view with your hands. This would be a perfect 4 or 5-minute video. Thank you.

Very cool !

A lot of good information thank you.

Good prepper item, Crisco.

My belt loops would get caught all the time. I ended up turning the latch 90 degrees, pointing down.
