Hi
Has anybody had any experience or thoughts about these lithium ion batteries?
Cheers Rohan

Not sure about the car battery but your post got me thinking about an electrically powered e30...

It would be an interesting conversion.100% torque at 1 rpm!!

I imagine once electrics are common sourcing the internals from a wreck will make this a possibility...

Still, acceleration with no roar from the engine bay?

Maybe thats for a younger generation....  ;)

You mean something like this? http://www.evdrive.com/design-technology/evdrive-train-architecture/modular-evdrive-trains/

Another company that could do the job for you. http://evwest.com/catalog/

I was looking into a hybrid by mounting an electric motor with gear reduction to the crank in place of the A/C compressor. Just waiting for the industry to mature.

Hi guys

Thanks for the replies, but I'm just talking about removing the lead acid battery and putting in a lithium ion battery. But I have heard that they don't like power fluctuations and can catch fire.

I mean who gives a sh*t if your phone catches on fire, I'd probably rush out and buy marsh mellows!
It would make my day, no more annoying calls from oxygen thiefs!

But if I install one in my e30, i would not be happy with a battery fire! :'(
Yes I suffer from e30osis :D

Thanks Rohan

A buddy of mine has a jumper pack with a Lithium battery, it's a nice piece of work. I've heard of far more Lithium battery failures than fires on my biker boards. The type of cells used in these batteries are probably not Li-ion, but LiFePo. You can get more power out of the older types of Li-ion, but they can fail in a very bad way. These starter batteries also have several fail-safes to prevent critical overcharging and shorting.

They're very popular for bikes, especially the Shorai and Ballistic. They're also cheap considering how much weight you can drop. That's a nice benefit with a car but critical on a sport bike.

Be sure you have a decent warranty. The auto-type starting batteries are compatible with most recent chargers and can be jump started from another car. Lithium is a bit needy - it does not deal well with neglect. I'd definitely recommend a trickle or solar charger as well. The $12 HF solar unit works well enough for me.
