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.

When i was racing karts our spanner man would do his nut if you didn't have a Yuasa fitted.

The only Lithium batteries you could use where the branded Rotax ones at a cost of £200 squids.. But they just disnt pack the same punch as the Yuasa.

Yeah I do, in fact I've got about 15kWh of lithium batteries on my bike... Twisted Evil

Some total loss race bikes use a capacitor to store energy already. They were around when I converted mine to total loss in 2007.

Odd choice for total loss.

Makes more sense for running a charging system - you have low energy density, but high power density, so you can get a big kick easily (starting), but it'll drain it quickly - so fine if the bike starts and then charges.

Most bike lithium batteries are lifepo4 - a 4s is very similar to 6s pb in voltages and they're less explodey too.

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

Not the case.

Otherwise you'd have to disable the charging circuit in the bike and run total loss.

You need to not use a charger which runs a desulfication program I believe - that gives short bursts of high voltage.
A normal basic charger or a smart charger that doesn't do this will be fine.

You can get a a flexible hobby charger for £20 for a mains powered one or £10 or so that will run off a 12v source if you do want a special charger.
And these chargers are useful to have anyway - they give you lots of information and will charge lead acid, ni-mh (rechargeable AA etc) as well as 3 different types of lithium.

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.

How amazingly?

Starts your bike when required? Powers the lights?

Fucking amazing, my lead acid cheap as chips does that amazing stuff as well Razz

Amazing that I know someone with the same battery they have left there bike sitting in a garage for 3 years. Went over for a visit and it started up first time. The bike was covered in thick dust and had stuff piled around it with thick dust.

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.
