Lithium Batteries

[Motorhate]

Anybody use one in their bike? I'm probably going to have to replace mine at some point soon and have been reading up on Lithium batteries and how they're lighter, last longer and just have more cranking power. Is it all hype or are they really worth the extra expense?

I didn't even know you could get Lithium batteries for vehicles.
Do they have circuitry built in, smart charging?
Something else with future potential is capacitors, should last much longer than conventional batteries in theory.

Lithium sound good in certain circumstances but good old lead acid from a reputable manufacturer (Yuasa/Motobatt etc) still seems the best all round choice.

Lithium batteries are very light in weight as compare the standard batteries plus they provides excellent performance.

Been running a LiFePO4 for around 9 months no issues, much lighter than the lead acid equivalent. Cranks harder. Wouldn't fit anything else now, my LFE addiction is terminal, positive experience has me converted.

Yep, had a Lithium Batt in my old R1. The bike seemed to eat batteries like sweeties, once i switched to lithium that stopped.

Please bear in mind that you need a special lithium battery charger if you want to charge it away from the bike. otherwise damage

Mine never needed charging off the bike, even having after the bike sat for 9 months on the drive way in all weathers.

The batteries themselves have low AH ratings, so be aware if you slap on loads of heated gear or whatnot. My one was 4ah, the equivalent model for lead acid is simply to check it has the terminals in the right place and fits the battery holder.

They don't self discharge like lead acid/ni-mh etc. In fact most damage is caused by over discharge past safe voltages (saved by lv circuitry in most commercially available batteries) and storing the batteries fully charged. Around 75% is ideal.

From racing high end electric rc cars we were fiddling with lithium polymer/lithium ion and lithium manganese packs for years. We have EFRA approved hard case armoured lipos the size of phones that can output over 200 amps sustained quite comfortably. And they cost absolutely fuck all. Infact all of these 'mini starting packs' that will cold start a dead transit are just one of these packs with a screen glued to it and a pcb.

Why cars/bikes are still fitted with conventional batteries is a bizarre anachronism to me.
