Battery died, should I go LiFePo?

Anyone have any experience with those types of batteries in the sv1000?

The life batteries are good. Very lightweight (around 3kg less) and good CCA. The bad thing with them is that they have limited capacity meaning that if you ever have charging issues(not unlikely with the SV) you will probably have problems to drive your way home. i was looking at the shido batteries ( http://www.shido-batteries.com) they have good reviews and are relatively cheap. They are made in japan i think. I am waiting for my Bosch pb battery to die to try it to my bike. Other good brand is the shorai. One note, you might experience problems on really cold weather with this type of batteries. You have to warm them up to work.

I've had a Shorai LFS14L2 in my SV1000 for a few years now (I have a custom subframe with limited space), no problems. If it's cold enough (bike outside in low 40s or below) it might crank a little slow the first time, but the battery will warm up and you can crank it for a LONG time before you kill it (probably a solid minute, but don't do that all at once - you'll kill the starter).

All of the LiFeP04 batteries I am familiar with have improved capacity, with equal to or greater Amp Hour ratings as long as you use the one specified for your bike. If you use a super tiny one, this might be correct.

This is the only draw back I have seen with all my bikes that have them. My winter commuter bike is a bit of a pain in the ass to start when it is 16F out, but always starts. I have had really long life out of my Shorais so far. Over 5 years now and working awesome.

Well, i had a look here http://www.shido-batteries.com/html/...ons/index.html and it clearly says that the capacity is less. I am not sure about the shorai, are they 12ah?

The equivalent Shorai battery for an SV1000 is rated at 21A hours. Even most of the smaller cased batteries with less output are equal to or over 12A hour rating. Spec battery for the SV1000 is a LFX21A6-BS12

You are right! Almost the double capacity for these shorai batteries! Shido battery seems of really small capacity.

Interesting! Do these batteries need/want to be on a tender like the lead-acid ones do?

Nope. They can hold charge for nearly a year when unhooked.

Think I'll try one then. Price difference wasn't that much compared to a gel battery

That is very cool! I'm still running the original battery which is going on 6 years now, so a fresh one is going to be on the schedule here soon. Might have to invest in some new technology.

Not quite. 21AhEq, not 21Ah. It'll start an engine similarly to a 21Ah battery.

A small drain, like an alarm, and my understanding is that it's about 1/3 the capacity of a 21Ah lead acid battery.

LiFePO4 batteries have very low internal resistance, so they can put out a LOT of current, but they don't have that high of a capacity when it comes to small loads.

This is always a good place to mention that having the ability to shut off your headlights, as well as monitor your charging voltage can extend your range should the charging system fail and leave you running total loss on the battery.

Rob: I put a Shorai LiFe battery in my SV-1000 two years ago. I am sold on this conversion. Lost 8# and really fires the starter! No problems in 40 degree weather, but some report problems in colder weather. Solution is to turn on ignition and don't try to start for 10-15 seconds. Warms up battery and then it's fine. Only hearsay, however.
