I've had good luck with ebay over the years, and the rare time I've had a problem, PayPal quickly refunds my money, and I don't have to deal with my bank.
I do buy on Amazon on occasion though.
But, that looks like the best lithium battery I've seen, price vs warranty and CCA.
That will be the one I order as of now.
I'm just going to wait until I Need it, vs having it sit on a charger waiting on me, or other parts.
Thanks for all the info, I appreciate it.
I don't throw shade on E-Bay at all. I still prefer them for some things. Like anything used or out of production they are great for. And yes to the PayPal.
Amazon seems to be where they offer the best prices on new things. And with a Prime account everything ships 2 day and free.
The battery purchase was the last one seller had in inventory. He has been previously selling it for $119.
Which even at that, it's a lot of battery. My concerns for Lithium batteries all seem to be getting resolved. Now you can't over charge them. The amp hours are way more useable than 2 years ago and are about twice what the equivalent lead acid is in the same space. The BMS shuts them off at danger temps.
The only thing my electrical brain is still rolling around is:
The LIon BMS does it's job to protect the battery. However when it activates it essentially opens the positive to negative circuit to open. There is no longer a path to ground.
An alternator doesn't know what it's charging. Lead acids never remove a load from the alternator. It just sends excess energy out to ground.
A LIon opens the load. Which to me seems like the alternator voltage regulator will run away in voltage until the diodes blow in the alternator. So in my mind, in theory, it seems like alternators are at some risk here if the LIon BMS triggers.
I'm not sure the likelihood of this in reality. They are still new to the motorcycle space, and they may have built in the electrical work around. The fact that I need a charger that is specific to the battery is what makes me ponder how our dinosaur alternators will manage this new stuff.
