Weight relationship fore to aft

Amazing isn't it. That many mAh in such a small package. My old-school brain doesn't want to trust something that small.

I wonder what our boat systems will look like in 20 years?
 
I am sure I have cured my Starboard lean when next to the dock...(common with the 22' ) but, I have not have a chance to test it in the water....I am doing other projects...things like carpeting the trailer bunks and fixing chips and scrapes in the gel coat... Today I am going to try to find some boat jacks to lift the boat up off the trailer so I can do the bunks....don't want to put the boat in the water and get the bunks wet...for me working on the boat is part of the enjoyment of owning a boat..

I recently retired from a luxury coach manufacturer. The house batteries we used were six Group 8D AGM's weighing close to a 1000 lbs. The 600hp Cummins also used two 8D's for starting. A lithium Ion battery manufacture was able to replace the six 8d's with one battery that weighed less than 1/2 what one 8D weighed, but with more amp hours than the six combined. The two 8D start batteries were replaced with a lawn mower size battery. Pretty amazing stuff but then again look what Tesla/Volt/Prius are doing with Lithium Ion.

Excellent points. A battery for the Prius hybrid is suppose to last about 10 years (according to the salesman). I haven't had a Li-ion battery for one of my cordless tools go bad yet, and one is now four years old. I think it's just a matter of time til we can fit two Li-ion batteries in one battery holder.
 
Beer in the bow is a practical and fun way to remedy a too portly stern.
But, excess imbibing may cause the original problem.

Aye.
Grandpa used to say, "A Gentleman never has more than 3 martinis
before dinner."
Grandma used to say, "Beer. Puts amps in my battery!"
 
Foggy, I think your Grandpa and I could have beeen real good friends, and your Grandma knows what she's talking about
 
I will say that adding a second battery to my starboard lazarette was an interesting endeavor. I had my kicker on the same side and moved it port, so the boat is more balanced now (slightly heavy on the battery side), but with more weight in the stern (and the kicker farther aft than it was) the boat does handle and behave differently. Most notably, if 2 or 3 adults want to ride in the cockpit instead of the cabin it can be tough to get on step when fully loaded.

I would actually like to put my batteries under my sink, and have a couple items that run straight to the battery intersect there. It's way down my list right now, but it did make a difference. Overall I'm happy with where everything is set up, and I think if I buy lighter batteries when the time comes (and maybe a lighter kicker too) I'll be perfectly happy.
 
Well, thanks much for all the input. I installed the second battery under the sink. That puts both batteries on the starboard side. Then I installed the kicker to port. The combo seemed to work well. The boat doesn't list. It is a bit stern heavy IMO, even after using 30 gallons of fuel, but as stated the trim tabs handle the balance. We enjoyed the boat on multiple outings during summer in and around Icy Strait and Glacier Bay, Alaska, where we live during summer. Love being able to get out on multi day trips.
