Anyone know about these lithium batteries?

I need a new battery on the Husky anyways & it looks like this will shave ~3-4lbs out of the bike.

I googled it and found a mention that these might be available cheaper at hobby shops? Does that mean it's an RC car battery or something? Any pointers? Would that have standard terminals like a regular bike battery?

Very interesting. Thanks for posting this.

While it sounds like a great idea, is it worth your $$$ to spend 3x as much as a regular battery for 5 lbs? It says it will last longer but who really knows.

Anyway, in the long run you are better off loosing 5 lbs on a diet, unless you are racing and then yes it is totally worth it. In the mean time its cool.

3x as much? A regular Yuasa runs ~80 bucks, this is $40 more.

Yuasa wants around $160 for a battery for my bike. That is why I'm not getting a Yuasa. I wouldn't get one of these either because I should loose 5lbs (or more). Until that happens I don't need a battery to do it for me.

A few things I would be wary of is it looks like the wires are higher gauge than what I normally see coming out of a battery. The battery may be lighter, but it still needs to deliver the same power to crank the bike over (I'm guessing your Husky is electric start). These batteries may not be designed with the application in mind for which they are being sold. With that in mind, these batteries also don't typically like rapid discharging (starting a bike) so it might not last as long. Last thing, if you start looking for another battery source do not look at Lithium Polymer (LiPo). They occasionally get all explodey on people.

we use lipo batteries in rc racing yes. they are great for that because we can run them all night at the track. multiple charges in one day. regular nicd or nimh batt could really only be ran once a night.
lipos are expensive, require a different charger (don't know how it would work with an alternator/ elec system of a vehicle) and they have a tendency to fire up. (as in, catch on fire) we have to charge them in a fire safe bag at the track.
for r/c use they are great, have great power potential and low weight.

I don't think Sean has 5lbs to lose.

The last few batteries I bought were from auto zone. I've bought a few and never had any problems with them except for one that wouldn't hold a charge after I left the key on and drained it, even then the parts store replaced it for free because it was less than a week old.

Well that made things clear as mud, thanks!
