thanks Catchalot ..interesting stuff indeed. Battery development is the new frontier in research that will change our lives incredibly. 

Still can’t wait for a very fast, free to run light electric boat...can’t be far off... oh and affordableConfused

Good idea...


This development will be good for getting the cost down but the batteries will weigh more than Li-ion (Na weighs 3x Li) and offer the same energy density limitations so not very good for a non displacement boat. Better for trucks and buses and perhaps cars.

As an aside also the talk about fast charging is a bit of dilemma as faster charging is associated with lower battery life.  That’s why your iPhone tries to work out what time you normally wake up and trickle charge as much as possible while you sleep.

Lithium polymer batteries offer great weight to capacity, but they are inherently unstable (bursting in to flange)and deteriorate when left in a fully charged state for any length of time. Hence those tiny jump start packs never last..

Just read your post,

For fun.... is it only women who burst into flange.
Are ordinary batteries insufficient for bedroom aids.
As most partners arrive early is this jump pack able to be worn without interference.
What group does the never last refer too.

Looks interesting as long as you are happy with displacement speeds and day boating only (range 100NM at 9kn)
