Lightweight Battery

Hi Folks
Has anybody changed to a alternate battery type and what was the outcome? Are they any good and worth the extra cost?

Thoughts please.

I have a Shido LiPo on my 1200R after going through 2 standard lead acids

Standard battery - 160 cold crank amps / about 3.5kg
Shido LiPo - 330 cold cranking amps / 1kg

Holds charge perfectly when not using the bike, spins it up really well. Liked it so much put the same on Mrs Pedro’s KTM

Got the 12R battery for £105, the KTM battery was a bargain at half price, for £55
Needed to buy a lithium capable charger, Noco Genius, about £50

I use Shorai only 1 failure but that was because I ran it over otherwise faultless in the last five years

Well ..... Misjudged a yump in the road which compressed the rear wheel so far that the tyre tore out the under tray which is where the battery was living, it then somehow found its way to the road under the back wheel and exploded into many pieces
Had to push the bike 3 or 4 miles home... was quicker than waiting for recovery
Anyhow battery didn't work after that hence the 1 failure

Is the short answer

I'm always misjudging yumps too, bloody nuisance. Kind of a similar story was a friend who wanted to move a half finished project across town so rode it only for the front mudguard to come adrift & rotate under the front wheel meaning he was then ridding with a front skid! Not recommended but only really damaged his pride.
Have also fitted Lithium battery & suitable reg no problems. Bitza

I try not to judge the yumps, they are what they are, it's not their fault.. You must expect them to turn nasty if you misjudge them.

Surprised to hear you are running a LiPo Ped. A Lithium Polymer battery is a different animal to a Lithium Ion completely. Interesting to learn that they seem to be accepted for use on motor vehicles though, I might investigate.

I have quite a few LiPo batteries, very energy dense, very high discharge rates but very charge sensitive.
The 'exotic' bike and car batteries do have regulators and charge balance controllers built in so that they don't explode the first time your regulator dumps a few more volts than intended into them.
The old damaged ones have given much fun as they aren't that safe to transport (I store them in a high temperature fire proof bag in a steel box) so I just kill them by puching a little hole into them. Sometimes you just get a jet of fumes come out, other the fumes ignite into a very realistic imitation of a blow torch just at a slightly higher temperature.
Great fun

I have had a Shorai LFX18A1-BS12 for the last few months. Very light and much improved starting performance. I use the bike most days or run the engine every week if there is a prolonged spell of bad weather so have not really needed a charger, but just for a test I have used my ordinary charger to top it up a couple of times. During this very cold snap I have followed the advice of warming it up a bit by having the headlight on for a few minutes before trying to start the bike. Seems to help. The Shorai does not have any on board cell balancing or charge protection, which is a pity because it is not cheap. The dedicated charger and leads which will balance the cells is another £90 so I live in hope of a second hand one turning up. Between the battery and exhaust I have saved about 6 or 7 Kgs.
