[Electric Boats] Re: Could you evaluate my project?

 

It was the technician I spoke to, that recommended the Gel-batteries based on the following:

- They cannot leak acid
- They can be discharged more then FLA
- They do not suffer the same way as AGM's if they are not FULLY (many hours) recharged
- In his experience (he has done this in many many years) life-time is better on Gel
- They are not that more expensive (here in Denmark about the same as AGM's)
- In my boat it would be an advantage that they can be mounted at a slight angle (lockers below settees)

That was the GEL arguments :-)
I haven't made a decision yet, still evaluating pros and cons.

He also mentioned this alternative (LifePo4) build as a system with 12 volt "bricks" but still Prismatic cells.
It might take some complexity out and weight down.
It does however not solve the issue that LifePo4's should not stand at full charge....

Nothing is black and white :-/ :-)
