Well, I donīt come here to argue. So I wanna keep this short.
[QUOTE=alansmith;2762349]Warrior, why would you say "we all have our opinions"....and then attack someone's opinion? John happens to be one of the guys who has a pretty sharp intellect and has contributed tons of information to fellow org members over the years i have been on here.
I am aware of that. The more I am disappointed.
Sorry I donīt know how to judge by the number of contributions. I go by the quality of content. I come to the forum for years almost everyday. However I donīt write that much. Thatīs what I do when I have nothing to say.

[QUOTE= but from an old guy... Hmmmm ?ŋ?
Where did that one come from ? Now You got me confused.
[QUOTE= it is not what you say...it is how you say it.
I agree, that was a pretty sharp and intelligent vocabulary on Johnīs behalf.
I started this thread to find others with ! interest ! in the topic..
I hope I am in the right place.
[QUOTE= Never a need to denigrate another's opinion. Debate and debasing are two different things.
Yeah, tell me about it.
[QUOTE=One method is sustainable as expanding the conversation and developing the discussion. The other is not sustainable because it creates bad feelings and marginalizes people's character.
I share Your point of view.
The EV market and energy storage are the main drivers of the battery industrie. However we should not get confused by the name of the company EV
POWER. Since years the are the only company in the EU that has stock worth mentioning to my knowledge. When I go to there website I donīt get the impression they are focused on the EV market. They even offer a 200 amp sailboat package.When I look at their product line I see them focused as the prime outlet of the mayor Chinese Lithium battery manufacturers in the EU.
Without any doubt GWL
POWER is one of those players, even so lately there brand is not that present in our latitudes. There are many
boats around the world that have their batteries on board on private iniciative or installed by specialized companies and till now I am not aware of any complaints. Also many others used their products in all kinds of applications.
That gives me reason enough to have a closer look when they come up with a new product, and even more so when those two names show up on the same spec sheet. Going through there description I canīt find any specific recommendation as to application like traction or energy storage that we are used to. However with LTO they focus on safety, much higher charge and discharge rates, by far superior life cycles and a much wider temp range specially on the low side. One thing is for sure in my opinion. The EV market in today s world is not the only one anymore with needs for fast charging and higher discharge rates and when it comes to our
marine application itīs a wild mix anyhow.
" one EV vendor selling another is no cause for excitement."
Well yes, that is boring.
But when a company like GWL POWER puts such impressive numbers on their spec sheet together with their mayor outlet in the EU market that is exciting. I would say itīs fair to asume they will back up what they promise on their spec sheet. At least till now I have no reasons to doubt their reputation.
This is not MAYBE ONE DAY. This is right now.
Yeah, I hope I am in the right place ?
So another thing that goes through my mind is the fact that most likely with with 30 amp standard
shore power and the
current charging methods on board I will never reach such a critical charge rate. Most likely with a proper sized battery bank I will also never get to a 10C discharge rate. As a result my batteries will never get hot and that will eliminate the need of the temp
sensor to watch my hard earned dollars 24 hours everyday. Well, I mention that because those temp sensors do fail.
I would like to have some comments of the experts on this topic.
Furthermore , now there is this new temp range that goes down to -55šC.
Well, till now I heard some pioneer hobbyists do all kinds of experiments with
electric heater pads,
insulation and what not to deal with the issues but it seems to me we are just adding on more and new sources of possible headaches. My pulse is always rising when I dream of all the possible sceneries in combination with stormy
winter nights way below freezing and the boat sitting in some marina while I am away a few hundred miles for some months. Yeah great, the last time I was there I remember the
weather was still warm but now itīs cold. I hope the thermostat of the
heater pad is working as promised or it will drain the batteries down below max DOD and then I have no
bilge pump.
Well there are not only pioneer hobbyists. There are also people like me with a wild imagination. I have been in the back shed but I find myself always coming back with empty hands or more complicated solutions due to technical limits of the technology.
Well. of course there are the Drop In solutions, supposedly suitable for the installations in
boats. I always look at them with a grain of
salt, specially when I see too many over priced black boxes. I have seen too many inside and today I understand that even the most advanced inventers have to buy components in the big pond.
Hahaha, wouldnīt it be just easier and less complicated if there is a better battery in the first place ?
The one from yesterday is not
Hopefully the one of tomorrow is better.
