LIon Batteries

Has anyone tried the Shorai Lithium battery?

I really want to give it a go but this scares me

Shorai Batteries require a charging system output of 13.1 Volts or higher at idle, and must not exceed 15.2 volts at maximum output.

They should work in the Vulcan. However a good AGM battery is a lot cheaper and should last 6-7 years.
The shorai batteries also don't care much for cold temps, so if plan on doing any riding before spring you might have some issues with starting.

What are the benefits over the AGM batteries? From what I understand the lithium is very good but does have limitations as KM stated and the price for lithium is pretty expensive. Not sure you will be getting very much for the higher expense and limitations (charging requirements and temps.)

and always remember, "Ride until you rot!"
**Really not sure if the Big "C" is back right now
but having to face the fact that this is a lifetime routine
going forward. Five operations done and it still continues.

I have one it works great
pros
charges from completely dead to full in 3 mins with jumper cables
has so much power it starts more easily in cold or extreme conditions
lasts much longer
easier on stator
lighter (by a lot)

cons
expensive
power is immense but not high amp hour


I kept mine on a battery float charger (150mA) for the coldest part of the winter jan-feb but it started right up without it, even in the 30s, and it started a few times in the 15-25 deg range, although it had just come off the trickle, it still was frozen and needed a minute of cranking to start and it powered through just fine. one time I left the lights on for 20 mins and it was stone dead but I got a jump and it started and recharged in minutes and unlike a lead acid that discharge did no damage, id say its worth it

it should last much longer than 20 mins with the lights on... something amiss there I think. either longer than 20 mins, or more draw than the lights/ign on.

I work in the industry and have to say I personally would stay away from them. Way more warrantied than not. Not to say some weren't user error but for the price of these things you would expect they are magic. Simple fact is they are not. Warranties are difficult and cold actually works against them. In lower temps per manufacturer it's recommended to crank a few times to warm the battery. Some have had success but it's really hit and miss.

it's battery time for me.

I've been looking around for a new battery and come across these, "Lithium batteries". as for the price.....I can find them for around $50 more, than what a AGM battery is going for right now.

as for weight? the AGM is around 12#, the Lithium is less than 2#!

if it goes vroom or boom, I LIKE IT!

Nothing wrong with saving weight, but it's not like the Vulcan is a featherweight to start with. I can see buying one for your big buck sportbike, but the weight factor won't make much difference on the 750.
Unfortunately I don't know enough people that have used these for more than 6 years to get a fair assessment of how well they perform.
I'm sticking with AGM's for now....

Lithiums often last less time than their AGM counterparts, and do not handle extreme weather as well.

The AGM made by YUASA is still $60 at Walmart.
