Today I was recomanded these batteries
Donīt just think chinese crap OK
manufacturing is very bad for health
and enviroment. So You donīt want it to happen in Your back yard.
Just using this web page to show the actual progress of the tech.
The positive points are known. High energy density,You can fully discharge more life cycles and less weight. No toxic explosive gases. Saves a lot of space, low maintanace.
Obviously all of those are very atractive advantages.
On the other side there are safety
issues. They can heat up, explode and controlled charging
is required. A more complicated BMS system takes care of that....but when it come to agressive marine
enviroment there is an aditional source for risk.
Now trying to be objective as far as danger
there are also technologies on board that I would categorize the same.
So how big are the risks ?
For instance on this particular web page they recomand allmost all applications less marine
.....yes a small beach hopper.They show big public transportation applications, but they donīt show a nice yacht
They talk about high safety
and qualify to UN38.3/MSDS、RoHS、CE、TUV、UL .....lotīs of prestige companies are associated
Also prices are coming down but as of yet in boats the good old deep cycle battery
still seems to be dominant.
Yes, lots of people talk about but in their boats they have half a ton of Deep Cycle batteries........
