Sodium Ion batteries
McCabe-Thiele (Ted):
Sodium-ion battery, that's a new one to me.
Developed for electric cars as they are lighter & cheaper than Lithium says Mr Google.
Be interesting to know if the need a special charger?
neat street:
Very interesting, what information do you have on charging?? can you use a mainting charger during winter? thanks for sharing.
Orcade-Ian:
To answer Bryan's very valid concern, apparently the info included from the German manufacture outlines that they are very tolerant to variations in charge current but the voltage should be kept below 15v. No mention of maintenance type chargers though. They can be left discharged and still pick up as normal, unlike lead acid. They can also withstand lower temperatures and be rapidly charged. I am fortunate that I have a stabilised power supply and can vary current and voltage, so will probably use that when needed. There is also a small button on the top, with 3 blue lights indicating charge level. As I say, early days yet but so far, very impressed for less than a Motobatt. Not sure yet if they will produce a whole range to fit different vehicle/applications.
Ted, I think Google may not be correct, the charge density is so small, it would need every EV car to have a lorry load of batteries with it! For us 2 wheel petrol heads I'm hoping it's a way forward.

Forgot to add: you can check it out at 'bikerstoolbox' web site and no, I have no connection with them!

I can't believe just how good this battery appears to be! True, at 3AH its not going to be any good if you leave all the lights on with the engine stopped but not many folk do that anyway. 300 CCA can only be drawn for a very short period (on paper 1/100th of an hour but less in practice). How long do we normally hold the starter button for?
As I say, very light in weight and no lead or cadmium - only sea-water as electrolyte. They will never compete with Lithium Ion batteries for EVs for charge density but seem fine for our usage.
I'll keep it on the Genny for a while (nothing to draw current when off) and then swap to one of the bikes - probably my 550 if all is well. Seems just too good to be true - bound to have an unforseen drawback but I like testing emerging tech.

They would probably run out of charge very quickly if a bike was reluctant to start.
Orcade-Ian:
Yes, you're right Gareth - that would certainly be a problem for a reluctant starting bike but the way it flings this Genny over when compared even with a higher amp-hour Motobatt, encourages me to try it on my 550 next. I will report back after I've tried it a few times. Wonder if the much higher CCA would help a bit with reluctant ones - providing all other settings and adjustments are correct of course - it certainly ain't going to cure blocked pilot jets!
