Ensure all your wires are secured properly and there is no chance of a short circuit. Improperly installed wiring and accessories would be the biggest danger of it being in the cabin. While installing lithium in our boat I could not get past this, so I put them in the lazarette. Didn't want...

Talking about future expansion. If you have room you will likely expand, having power is addictive. You say 100/20 for a 24 volt system but you said you have a 12 volt system on your boat. For a 12 volt system You will need double the amperage the calculator is saying for 24 volts.

Even the Victron controllers do not like being up near max. If you have room for more panels go for the 100/50. You wont regret it. I started with 200w, went to 400w and now am at 690w. Ended up buying three different controllers.

Mariner Blue, Hard panels seem to be the best. I have had four 100 watt Renogy panels on my boat for the past seven years. They have worked great and put out 400w to this day. Upgrading to two 345 bifacials this year for more power and building a hard top for it. An arch is one of the best...

You realize that you are doubling your usable power with 400ah of lithium, correct? Two separate batteries let you disconnect one of them in case of failure and still have power. We have a C&C 34, great performance but how did your 35 handle off shore for weeks at a time?

645 watts of solar fits on a C&C 34. It uses up my entire bimini top, but what else am I going to use that for? Don't see much problem with a larger bank. You can always use more power if you want to cycle your batteries.

Thanks Steve! Great resource.

Thanks for the thread. This helped me out quite a bit. Ended up buying two LG345 bifacial panels form CED Greentech and it was only an hour drive. Ended up being cheaper as there was no shipping. Staff was super friendly and helpful.

Agreed. Avoid at all cost! I had to open a PayPal case before they would refund money. Even after they agreed to!!!

Not exactly. This was supposed to be the "Smart 100AH battery"

They agreed to refund my money and said it would take 48 hours to process it, that was 10 days ago. Still no refund. Had to escalate with PayPal. They did send a return label for the wrong battery and arranged shipping. I would avoid this company.

A little fish may be an understatement.

Where are you using this boat? Lake, river or ocean? Where you use it makes a huge difference. It is highly unlikely you are going to motor 2 hours at full power. Most new trolling motors have warnings about using them at high power levels for long periods of time anyway. The motor can be...

Yesterday. They told me a few hours ago that they would ship out the right one first thing Monday. We will see. Good luck, I hope you get the right battery.

Consider yourself fortunate to have "missed" the "sale". I bought one of their "Renogy 100ah Smart Lifepo4 Batteries" They sent me this:

Sorry I didn't see this earlier. My dad has a 24volt MinnKota Ultetra Riptide 80, put together a 190 ah LifePO4 and it was a huge overkill on his 17 Boston Whaler. He is fishing in salt water with a very strong current. It took him 10 trips fishing for at least 3-4 hours in current to bring the...

Yes you can build your own battery, but it does not mean it is a good idea. Too big of a risk. As you know you can't walk or swim home from 8000 feet. Go with the Concorde battery and get a battery maintainer. If you can't afford to change a $260 battery every couple years you should get out...

I do not have the exact height as the batteries are installed in my boat, but used this 8" wide piece of aluminum from McMaster. 3' piece was big enough for 2 packs (4 plates). https://www.mcmaster.com/catalog/126/3888 P/N 8975K443

If you want to buy aluminum everything than that is fine, it is just unnecessary. This whole galvanic corrosion thread is WAY overdone. The problem with a 7 page thread about galvanic corrosion is that it discourages people from building packs because they start to think "Geez another thing to...

If you have all like materials then by all means use like materials. As long as the bus bars can handle the draw and it wont take much at 27 amps.

Unless you are in a very high humidity environment this whole thread is way over board in my opinion. Use stainless studs, keep it clean and maintain the connections at least annually. Pull the bus bars off once a year for inspection/cleaning and if it does it for you smear a little Noalox on...

Last night I saw Will was doing a live stream and figured he would post it later as he normally does. It isn’t showing up on YouTube. Just curious what is going on and the break in videos.

Interesting. One question comes to mind, why would you use a propane generator? You already have the infrastructure to install a diesel one, fuel is much more easily available and it is also considered safer by a majority of the marine industry.

There seems to be worry about galvanic corrosion here that is not likely warranted. Has anyone even seen any corrosion on any of the aluminum studded cells? If so I would like to see the pictures. If you keep you cells in a box in a half way decent environment your going to be just fine. For a...

This will be much easier: DampRid 4 lbs. Fragrance Free Hi-Capacity Moisture Absorber

12 Volt Flexible Monocrystalline Solar Panel All kinds of options here.

I just leave my regular panels on, no issues. A good solar controller will take care of it. 400W of Renogy 100W panels with a Victron 100/30

Yes, it is a bad joke. No solar panel either.

Check this out I might get two!!! Only $345!!! Many happy buyers!!! EZ SolarThe Survivor 2000/4000 Watt Deluxe Solar Generator/Power For Disasters

Those balmar temp sensors like to fail so its a good idea to keep a spare one around.

Hi Chuck The thing in the middle of the U channel is a threaded rod. On the outside of the U channel is 5/8 clear vinyl tubing for chafe protection. Yes I did build it and ordered most parts from McMaster-Carr. I'm putting a list of the parts together for another thread and should have it up...

I built up this pack and dropped it into a Todd Universal Marine Battery box. It is about 1" taller, wider and longer than a group 31 battery box. Heavy duty and fairly reasonably priced. Todd Universal Battery Box

Sorry I did not. The picture kind of explains everything. I'll list all the parts if that helps you out.
