Shorai battery for KTM990/LC8

It's not that big of a difference but of course it's difficult to transfer that heat to the battery internals and it may take some time like you said.

Okay now some experiences and closure to my shorai story.

If you could switch the heating on 1 hour before starting it might help slightly. Less than that and it didn't make any noticeable difference.

But now my shorai has made its last starts. After a night of -5 C it could not start at 0 C. After few tries it slowly died completely. Voltage is still good, 13,3 V but it can't even turn the bike on. I mean when I turn the key, bike might blink dash lights and then just shut down.

Now with new lead acid battery it starts like it was "under a palm tree" at sub-zero temperatures.

There is a very good thread on these batteries in the F800 forum by our own battery expert JoelWiseman.. Long story short, if an RR charges at less than 14.4 volts = big problem. If it charges at more than that, then less of a problem, but still there is one.

Most excellent said thread

I have a 3 month Ballistic EVO 18 cell and last Sunday after a 32 degree F night I had to let the bike site with lights and heated grips on for 3 60 second counts a with a 30 second rest in between before it would crank over. Have a new Ricks voltage regulator cranking out 14.9 v from idol to 5000 rpm. I might run it for the summer then it is going and a Deka lead acid is back in the bike. It is a pain trying to heat the battery up in the cool or cold days.

Hi!

Can anyone measure the size of the BMS connector on a Shorai?
I'm planning to make a cable and the battery is behind sw crashbar. If someone can reach the battery any better than me, than I don't have to take my bike to pieces :)

Thanks

That's what they call a 4S (JST-XH male) connector and you could find the wire extension at any RC store. I got mine here, but you'd need to make a wire extension with 2 female ends (out of 2 male-female wire extensions) in order to connect to any balancing recharger or monitoring voltmeter. I'm not sure if you can find wire extensions with female-female connectors, but you surely can find the connectors and cables separately in the same RC stores (like this).

My Shorai Died after a year of service
I charged it & it was still dead.

I replaced it with a East Penn Deka AGM Battery

Longevity is what I'm seeking

GDit. I'm just heading to the garage to install my new expensive Shorai... I guess we'll see.

Mine just died after 14 months.Not Happy !

I have killed 2 Shoria batteries in my 450exc. Both replaced for free. I bought one for my 950. With the issues I have had I will never install it on the 950. I do cary it as a spare in my tail bag along with custom jumper cables.

Glad I saw this thread, my battery is due and I was going to buy one of these... phew.

Mine is dead too! I'm very aggravated about it. Is the weight loss worth it?

You tell us what you decide to do

I'm just at a year on mine in the SE. I guess I'll find out this winter (NJ) how it does.

Curious if you guys are using the Shorai battery charger? The nice thing about the Shorai charger is that it individually balances and charges each cell. First battery failed in about six months -- on a regular trickle charger. New battery has been rock solid for 18 months on the BMS01 charger/monitor.
