Lithium-ion ATV battery

[bruceba]

Went to the local battery shop to get a replacement battery for the quad. I've dealt there for more than 25 years and when I get ready to leave the owner whom I had been chatting with asked me to demo a new battery for several months. He showed me a lithium-ion battery saying he wants it put through the paces such as cold starts and excess winch usage. No charge just abuse it and form an opinion. Right up my alley with all the snow I've moved lately the quad and winch for the blade has been going steady.

I looked at getting a pair of those to put into my car long with an ultracapacitor setup. Just never got there, and wound up at crappy tire.

Any idea on the price of one of those?

That's not a bad price for the battery. I don't know of to many that have the proper charger for the lithium betteries.

Cold weather performance from rechargeable lithium batteries has typically been very dismal. Hopefully they have figured this out. I really can't see any benefit that would put weight the negatives that I know from these batteries. They do normally have more power behind them than a NiMh battery would but about the same as a lead acid. I don't see weight being a factor to go to these batteries either as most machines have a ton of power and the few extra pounds shouldn't hurt.

I'm interested to see the results for sure.

I will openly admit that I have absolutely no knowledge of Lithium-ion batteries for vehicles, so this is all new to me.

I know that if I buy a good quality lead-acid bat (and take proper care of it) I can get about 7 years use out of it, on average. The ad linked in post #1 claims these new Lithium-ion bats have five (5) times the cycle life of a lead-acid bat. Does this mean we can expect a these Lithium-ion bats to last ~ 35 years?!

Just askin,

Mac

The cold seems to be a factor with the Li ion batteries. However, it's said to be a lot less of an issue with a LIFePO3 battery. I'm very interested to hear the results of starting with this battery in the cold.

The cold was the reason that I was thinking of adding an ultracapacitor 'battery' in the mix. I hooked one into my car in -40 when the lead acid battery would hardly turn the car over, and it started the car like it was +20 outside with a warm engine. Unfortunately, the draw from the security system overnight killed it. It only took a few minutes to charge however...

I also had the battery go on the swather. I was bored, and hooked it in while dad went to the city to get another battery. It would start that 4 cyl cummins like it was nothing all the way down to the bottom of the red zone on the volt meter. I did that by starting the swather and immediately shutting it off till it was having trouble starting. Then I ran the swather till it was charged again. 2:45 aprox. I didn't run a stopwatch, but watched the times on my phone. Boy, did that alternator scream while it was charging. One knew when it was done...
