Let's press PAUSE on the Galley renovation, as earlier this week, we received a VERY special delivery!
When we started this journey, we had Lead Acid batteries. After 3 years and failing countless of times, it was finally time for Uma to have a new lithium iron Phosphate heart

Really interested in this, I'm considering doing the same but there is so much conflicting information. Can you give us full disclosure, are you being sponsored. I have full confidence that you will be truthful, I just know how hard it is to mention the negatives in that situation.

@SailingUma 6 лет назад

It is a sponsorship... We dont consider that to be a negative! They are a great company, and we only try to work with the trust worthy ones out there. But going lithium was in our plan since day 1, so if its wasnt with a collaboration, we would have found another way to get there.

@whereswaldo1191 6 лет назад

@@SailingUma No problem, you'd be mad not to, didn't mean any offence, I've heard so many positive and negative comments about lithium that I have no idea what's what and it will be good to watch some real world results rather than listen to armchair computer warriors in there mums basement. I just wanted to understand where you were coming from.

@SailingUma 6 лет назад

Glad to hear it. We're excited to get out and test them too. Full disclosure, we never collaborate with companies that come with stipulation. It's one of the reasons it takes us so long to upgrade things sometimes. But many companies want you to say certain things, or title your video certain ways. But we always turn them down. We always choose companies that let us go our own way. It's a good way to weed out cheap from quality. If a product is good, and the company trusts it's own stuff, than they know it and we know it and then you know it. We turn down SOOoO many offers that come with scripts or talking points or other stipulations, but those just feel dishonest to us. Hope that makes sense.

@bobrose7900 5 лет назад

As soon as I saw those batteries I thought... COST! We are looking at an older boat to buy and the issue of battery condition has been raised more than once. A small new diesel engine can be had and fitted for 8k, sail drive optional over and above. The boat has been chosen for sailing performance - the engine is for backup only. What surprises me is the consumption of many of the, no so large, motor boats- 1 gallon a mile is common. Deep pockets or a total aversion to sails and the environment (whoops, another can of worms), Regardless, an absolutely fascinating blog and so well presented, and a terrific response from your audience. What an informed bunch they are! It's taken me ages to read a just a small proportion. Lots to digest for the future, but, regrettably, no panacea it seems. Well done!

@toddabrahamsson1797 4 года назад

I have done a lot of research on lithium. You are the first person I have seen installing lithium in a sailboat who seems to really understand the product ! I await your testing of your systems and the new lithium install. I think you will be very impressed as to how long the lithium last under load. Now you need to show the viewers your solar charging and explain it’s capacity. Great job !

Dan, I hope that between new batteries, new sink, new toilet, plywood plates everywhere, a lot of fiberglass plates being added, UMA will still be able to keep herself afloat. Please watch your waterline carefully. You don't want her to sit too deep in the water, especially in rough seas. That being said, your skill set is just AMAZING!!!!! Love you both.

@SailingUma 6 лет назад

Not much changed in the weight. She's actually sitting higher on the water than before and she's better balanced.

@russellosborne8795 4 года назад

A bit late now but I have just found you. You have a hell of a lot of current potential in those batteries . Speaking from experience with telco 48V systems, if you work on the terminals again wrap your spanners in insulation tape. If you short the spanner to the steering cable you will need a new wire and spanner, plus flash burns. - Seen it happen.

@abuskirk08 6 лет назад

I have watched all your videos from step 1! You both do such a great job on your channel. I really enjoy your DIY steps and explanations the most. Keep up the great work Dan and Kika, and Thanks for all the great knowledge and entertainment.

@michaelbrown2443 4 года назад

Battle Born Batteries have been great for us. With an inboard, when you're out of fuel, you're out. With solar and regen, the electric motor range becomes unlimited, just not all in one long session.

@thegarbone 6 лет назад

I hate to be one of those guys on the RU-vid but I work with battery strings pretty much every day. Get a torque wrench for all those battery connections. Torque them to spec so you do not get a repeat of what happened the last time a connector came loose. I would suggest taking the jacket off an old wire an putting it over the steering cables and taping it in place. Had a coworker installing a string of batteries with non insulated tools, one light touch of a socket wrench to ground later he had to go to the hospital with 3rd degree burns on 3 fingers. Even a double wrap of vinyl tape is better than no coating on the tools. I would make the trays more of a basket to allow for air circulation and possibly put boots over the exposed posts, hate to see the steering cable part, short two terminals and start a fire. You guys are doing good work, keep it up and stay safe.

@stargatepioneer 6 лет назад

I started watching your channel in January 2018 largely because I was intrigued with your electric motor conversion, DIY projects and the fact that two college grads could go sailing with almost nothing in the bank. I think it is very fitting that I caught up to "real time" with this video and the full electric conversion to the Lithium Iron Phosphate battery bank. I'm excited to learn their motoring performance as you cruise over on the other side of the pond. Good job Dan! You have definitely inspired this old guy with your energy, enthusiasm, and environmental thinking. Keep up the great work you two and have fun in the UK!

@PaulAdamsWatchman 3 года назад

Funny, not too long ago you had Captain Brian from Delis sail with you. The batteries and accompanying equipment are all the same make. I get the feeling he played a major influence in what and how. He is BRILLIANT with that stuff. You did REALLY WELL in installation and EXPLANATION. 😉

@SailingUma 3 года назад

We actually didn't even know he had similar batteries until after we installed ours. It's funny, when sailors get together, the last thing we talk about is sailing.

At 11:48 RE Interference on your radio: Study how to reduce that via using CHOKEs and winding your wires together (vs running them straight) etc... Google: How to reduce radio interference on a boat. Also, now you have more batteries to charge so they may charge quicker but take a lot longer if they charge fully at all. Even 5 hrs of motoring in a storm or emergency like a dismasting etc is not much so I hope you have a great generator and plenty of fuel for it. I know you must as you two are really doing a bang up job at all of this! Great & informative videos as always!

@onthebeaches 6 лет назад

Dan...great stuff as always. As far as the noise interference on your VHF, it may behoove you to put some snap-on Ferrite core RF chokes on those cables. They are fairly reasonable and do wonders in a super quick fashion.Also a wise choice to move your cables to the other side if not to much of an inconvenience. However, I'd try the Ferrites before doing the extra work Other tips and tricks are to keep you cables as separate as possible so they're not bleeding over into each other. I'm sure if you ask our good friend Google about reducing marine electronic noise, he/she will have a lot of suggestions! I'm excited to see if your math works out as I have my own theories about your numbers. PEACE OUT! Ü

@derekfreeman6888 6 лет назад

Love the upgrade to Uma!!! This will help you out in so many ways besides your electric motor. Delos also added Lithium battery banks without people knocking them on the cost. Uma do your thing and enjoy. Again, Just Catamarans are the bomb for their continued support of Uma and crew. ps...you could use heat shrink on that cable above the batteries to eliminate grounding out if applicable.

@findingsimon 6 лет назад

You guys were a huge inspiration for me going electric on my build and I'm happy to see ya get some real range extending lithium. I started with lithium but I wasn't as smart as you and went with used NMC Lithium Ion and it's a freaking handful. 218 batteries and each needs balancing, monitoring and cooling. Lifepo4 is so much simpler. And less explosive.

@CAv-lp2qk 6 лет назад

Great to see you going Li with new shore power charger and inverter too. Going to make such a difference!! How did you retain them all to the hull in the end?

@williambunting803 5 лет назад

That is really cool. I want to put lithium batteries on our Southerly boat (4 kilowatt hours) but was told it wasn’t the best option. Not convinced by the knockers so I’m watching closely. I was designing a 39ft Bristol Channel Cutter, but cut the corner and bought a 16 year old boat instead. But in that design I had planned a hybrid drive with a smaller diesel aft under the rear cockpit floor with its output shaft pointing fwd into a v drive box and with a 6 or 8kw motor mounted on the fwd end of the v drive. My expectation was to be able to electric power for half an hour to get out of berths and off anchorages to sail, regeneratively recharge under sail or solar, while saying that any diesel used would be biodiesel as far as possible. Well now I am fully conventional so have to find a way back to the original plan. Great to see your work and I love your interior.

@STONEDARTphotos 6 лет назад

I have a ten gal. tank, at five knots this is over thirty hours of endurance. The amount you spent on batteries alone over the last three years buys a lot of fuel. I do have lithium batteries and an induction stove top but for propulsion I am keeping the engine. Your installation of the batteries and components looks first rate.

@SailingUma 6 лет назад

Yeah, we always say that if you have a working diesel, keep it. But for us, we got such a good deal on the boat because it didn't have a working motor. Our original set up cost less than $1k including the solar. We spent another $1k on replacing batteries (our mistake). Still less than even a refurbished diesel. If you want top of the line electric with Lithium bank, it cost about as much as a new diesel motor ($10-20k). The only issue is you're stuck with a 30-50nm range per charge. For us, it's not an issue, since we can sail pretty much everywhere anyway.

@bunnita123 3 года назад

If your really annoyed about EMC interference on your radio. You can switch your wiring of your solar setup for EMC shielded cable. It has a metal mesh around the the wires that keep emc inside the cable. Like the metal mesh in the window of a microwave.

cover your wrenches and screw drivers either with electrical tape or non conducting heat shrink. that should take away the fear of shorting out your batteries in case you accidentally come into contact with something else metal. Rubber gloves are a good idea. I’m a electrical engineer who works in power plants and I must say that you have done some pretty good research and planning! Additional I'm writing this about 2 years after you posted this video(1st time I'm watching this) so you may already know.

@davidhagler6157 6 лет назад

I picked up on the same amount (just for the batteries). Maybe I am old school, but it seems like a lot of cost and effort for only about 4 hours of motoring. I appreciate trying to minimize the use of fuel, however, it seems like with the current technology there is still a lot you have to give up when you opt to not use diesel as an auxiliary power source. I enjoy the channel and appreciate the work you put in to the boat. I also am interested in the arrangement with Just Catamaran. The use of their A/C, car and shop have been a big benefit to you and would not be available to the average 'DIY' person trying to outfit a boat. Congrats.

@SailingUma 6 лет назад

For us, it's not really about fuel costs and money. There are many reason we chose to go electric, and we wouldn't go back. Clean, quite, simple, no maintenance, no smell, no vibration, less weight, better for docking and anchoring. On a personal note I like working with clean electrical and really don't like working with oily petrol motors. It also forces us to be more in tune with the ocean and elements and become better sailors. For us there really are no cons for going electric and almost all cons for diesel. But that's just us. Others have their own preferences and that's ok too.

@RealityIsTheNow 6 лет назад

Sailing Uma TO BE CLEAR: Nobody is questioning the decision to go electric...I'm questioning the logic of dropping 12 thousand dollars on batteries. Yes, they are better for your application than a flooded battery bank, but are they really 10 times better? Doubtful. This looks to me like an extremely expensive case of early adopter's tax. In 10 years, when they're ten times cheaper, I'll be interested. But hey, it's your boat, your money. Thanks for the video. :)

@edbourgoine5022 6 лет назад

One other note (now that you already have it wired up :) ) Get a couple pieces of garden hose and slit them along the length.. place that over the steering cables when working on the bat wiring and you won't have to worry about a wrench shorting out.

@ChrisBeardsley 6 лет назад

@harleyclark2508 5 лет назад

I am installing an electric drive in my Tartan 34 and am using the LIFEPO4 100 ah prismatics in a 16s configuration . My biggest issue is wiring the BMS, so the choice you made to have the BMS integrated into the battery saved you some headaches. Looking forward to hearing about your experiences with the new system. I have been following you from the start. Great work!

@SailingUma 5 лет назад

Yes, that's one of the main reasons we went with these over others. The integration of the BMS and electronics makes installing them easier than normal lead acid.

@mikev4820 6 лет назад

Hello, great videos. I may be stating the obvious but...I noticed when you were tightening that last positive lead (and you were wearing gloves because of a slight short between your cable and hand) you came close to touching the cable with the wrench. Whenever I have had to put the positive lead on last (usually it's best to follow the old rule "negative off first and on last") I wrapped my wrench or any metal tool with electrical tape. Any slip without it and the results are like a Canada Day evening celebration! I speak from experience :( Your attention to detail and overall skills are a real pleasure to watch. Thanks
