    You are right, to ease you mind all the differences regarding the capacity capability c-rate etc... are well known to me. I am not really known to my spell corrections so please excuse me 8) If you go to my lifepo4 pdf you will see a comparison between cylindrical cells and prismatic cells...

    Here they are: *just one note, all of the cell prices are incl tax and removal supplements if i would have bought these they total price you see would go down with about 25% (this depends of each cell). Only the Lifepo4 costs are what they as they are stated.

    Electric 22 feet speedboat from 1957

    Well yes... you are totally right, the hours are not worth the costs. I have done some comparising between all the different battery systems that i can use for my ''little'' project. The outcome is that i have change my mind on the 18650 project, instead i will go for Lifepo4. In about 2 weeks i...

    Electric 22 feet speedboat from 1957

    I disagree with you on that one, it is the intention to keep the boat as original as possible. When going for an inboard the weight will become problematic, i will need an prop and rudder going through the hull which the hull really is not made for (overlapping mahogany planks of 5 mm thick...

    Electric 22 feet speedboat from 1957

    The controller can handle max 550A at 118V battery voltage but i will never reach the 550 amps. at least i hope so! the motor will be 22kw nominal so that would mean with a pack voltage of 100v a draw of 220 amps resulting in 3,7 amps per cell. which is a little over 1c. i think that when...
